摘要 :

To improve the removal capacity of NO + O2 effectively, the alkaline earth metal-doped order mesoporous carbon (A-C-FDU-15(0.001) (A = Mg, Ca, Sr and Ba)) and Mg-C-FDU-15(x) (x = 0.001−0.003) samples were prepared, and their physicochemical and NO + O2 adsorption properties were determined by means of various techniques. The results show that the sequence in (NO + O2) adsorption performance was as follows: Mg-C-FDU-15(0.001) (93.2 mg/g) > Ca-C-FDU-15(0.001) (82.2 mg/g) > Sr-C-FDU-15(0.001) (76.1 mg/g) > Ba-C-FDU-15(0.001) (72.9 mg/g) > C-FDU-15 (67.1 mg/g). Among all of the A-C-FDU-15(0.001) samples, Mg-C-FDU-15(0.001) possessed the highest (NO + O2) adsorption capacity (106.2 mg/g). The species of alkaline earth metals and basic sites were important factors determining the adsorption of NO + O2 on the A-C-FDU-15(x) samples, and (NO + O2) adsorption on the samples was mainly chemical adsorption. Combined with the results of (NO + O2)-temperature-programmed desorption ((NO + O2)-TPD) and in situ diffused reflectance infrared Fourier transform spectroscopy (DRIFTS) characterization, we deduced that there were two main pathways of (NO + O2) adsorption: one was first the conversion of NO and O2 to NO2 and then part of NO2 was converted to NO2− and NO3−; and the other was the direct oxidation of NO to NO2− and NO3−. © 2020

摘要 :

研究了不同水热老化温度对钾(K)中毒0.4K-Cu-SAPO-18样品的结构及其NH3-SCR(NH3作为还原剂的选择性还原技术)催化活性的影响.结果表明,K中毒对样品结构影响较小,但明显降低了其NH3-SCR性能,在350℃时,K中毒样品0.4K-Cu-SAPO-18的NO转化率为65.88%,明显低于未中毒Cu-SAPO-18样品的90.85%.水热老化温度明显影响催化剂的结构,减少了活性位点,降低了表面酸性.随着水热老化温度升高,催化剂的AEI结构被破坏,活性物种数量降低,催化活性明显下降.氢气程序升温还原(H2-TPR)结果表明,孤立的Cu2+和Cu+的总量分别从未中毒Cu-SAPO-18样品的66.61和1.32μmol/g变化到K中毒0.4K-Cu-SAPO-18样品的39.52和101.96μmol/g,表明K中毒样品中孤立Cu2+容易转化为Cu2O.K中毒后,样品的弱酸、中强酸、强酸性位点的数量降低,分别从未中毒Cu-SAPO-18样品的0.201,0.103和0.302 mmol/g降低到中毒0.4K-Cu-SAPO-18样品的0.102,0.086和0.071 mmol/g.氨气程序升温脱附(NH3-TPD)和原位红外结果表明,K竞争性地取代了催化剂中孤立的Cu2+和H+,使K中毒0.4K-Cu-SAPO-18样品的活性位和酸性位减少,导致催化活性下降.在低温NH3-SCR反应中,K中毒和未中毒样品均以Eley-Rideal(E-R)和Langmuir-Hinshelwood(L-H)机理进行,而L-H机理占主导地位,但K中毒样品的反应速率明显降低.

摘要 :

The Ni-loaded cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) catalysts (xNi/OMS-2: x = 1, 3, 5, and 10 wt%) were prepared by a pre-incorporation method. Physicochemical properties of the as-synthesized materials were characterized by means of various techniques, and their catalytic activities for CO, ethyl acetate, and toluene oxidation were evaluated.The loading of Ni played an important role in improving physicochemical propertiesof OMS-2. Among all of the samples, 5Ni/OMS-2 exhibited the best catalytic activity, with the T-90 being 155 degrees C for CO oxidation at a space velocity (SV) of 60,000 mL/(g center dot h), 225 degrees C for ethyl acetate oxidation at an SV of 240,000 mL/(g center dot h), and 300 degrees C for toluene oxidation at an SV of 240,000 mL/(g center dot h), which was due to its high Mn3+ content and O-ads concentration, good low-temperature reducibility and lattice oxygen mobility, and strong interaction between the Ni species and the OMS-2 support. In addition, catalytic mechanisms of the oxidation of three pollutants over 5Ni/OMS-2 were also studied. The oxidation of CO, ethyl acetate, and toluene over the catalysts took place first via the activated adsorption, then intermediates formation, and finally complete conversion of the formed intermediates to CO2 and H2O.

摘要 :

The composite of gold nanoparticles-graphene oxide (AuNPs-GO) was prepared and characterized by transmission electron microscope (TEM) and ultraviolet-visible(UV-vis) spectrophotometry, respectively. The composite was modified on the surface of a glassy carbon electrode (GCE). The mercapto-modified and guanine-rich DNA strand (T30695) was self-assembled on to gold nanoparticles on the surface of the electrode via Au-S bond. T30695 could combine with lead ions (Pb2+) to form a stable parallel G-quadruplex. The G-quadruplex further combined with hemin to form DNAzyme with peroxidase activity. On the basis of this, DNAzyme electrochemical sensor Pb2+ detection was prepared. The DNAzyme could catalyze the oxidation reaction of hydrogen peroxidetowardshydroquinone (HQ) to achieve the amplification of electrochemical signal and highly sensitive detection of Pb2+. Under the optimum conditions, the peak current of square-wave voltammetry (SWV) was linearly dependent on the logarithm of Pb2+ concentration ranging from 5. 0 x10(-9) mol/L to 1. 0 x10(-6) mol/L with a detection limit of 1. 0 x10(-9) mol/L (S/N = 3). The recovery of Pb2+ in real water sample was 96% -105%. The sensor possessed good reproducibility, stability and selectivity to Pb2+.

摘要 :

The porous carbon (CKC-X-Y, CKC is the corn kernel-derived carbon; Xis the activation temperature; and Y is the KOH/CKC mass ratio (2, 3, 4, and 5)) adsorbents were prepared from corn kernels by the KOH activation method. Textural property and oxygen functional group amount of the CKC-X-Y sample were influenced by the activator amount and activation temperature. Among the CKC-X-Y samples, the CKC-900-3 sample displayed the highest surface area (1943 m(2)/g) and the largest pore volume (1.10 cm(3)/g), whereas the CKC-900-4 sample possessed the highest amount (45.5 %) of oxygen functional groups. The CKC-900-4 sample exhibited the largest CO2 adsorption capacity (3.63 mmol/g at 25 degrees C) among all of the CKC-X-Y samples. The results indicate that the activated corn-derived porous biochar with a high surface area and a high oxygen functional groups amount possessed a large CO2 uptake. In addition, the CKC-X-Y samples showed high CO2/N-2 selectivity, good recyclability, and easy regeneration behavior. The adsorption of CO2 was physically and chemically adsorbed on the surface of the CKC-X-Y samples, with the physical adsorption being dominant. In which CO2 was mainly chemically adsorbed on the samples with hydroxyl groups.

摘要 :

The Ba-CMK-3(x) (x was the Ba(NO3)2:CMK-3 mass ratio and equals to 5, 10, and 15 wt%) samples were prepared by the incipient impregnation method, which were used for the adsorption of NO + O2 at room temperature. The samples were characterized by the XRD, BET, TEM, TPD, TG, and DRIFTS techniques. The results showed that the CMK-3 and Ba-CMK-3(x) samples possessed an ordered two-dimensional hexagonal mesoporous structure, and Ba was uniformly dispersed on the surface of CMK-3. After Ba doping, the surface areas and pore size distributions of the Ba-CMK-3(x) samples were altered due to the synergistic effect of partial blocking of the channels by Ba and partial etching of the carbon materials by O2 produced from Ba(NO2)3 decomposition at high temperatures. The sequence in NO adsorption capacity was Ba-CMK-3(10) (108.1 ± 0.55 mg/g) > Ba-CMK-3(15) (106.2 ± 0.72 mg/g) > Ba-CMK-3(5) (102.3 ± 1.33 mg/g) > CMK-3(88.8 ± 1.15 mg/g), with the Ba-CMK-3(10) sample showing the best (NO + O2) adsorption performance. We proposed the two main adsorption pathways in the process of NO adsorption: (i) NO reacted with O2 to form NO2, part of NO2 were weakly adsorbed on the surface hydroxyl groups, part of NO2 were adsorbed to form the nitrite and nitrate species, and the left NO2 was disproportionated to the NO, NO2-, and NO3- species; and (ii) NO was directly oxidized to the NO2- species by the oxygen-containing functional groups in carbon, and then some of the NO2- species were transformed to the NO3- species directly or via disproportionation. The regeneration efficiencies of the Ba-CMK-3(x) samples were slightly inferior to that of the CMK-3 sample.

摘要 :

Different Cu contents (x wt%) were supported on the cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) (xCu/OMS-2; x = 1, 5, 15, and 20) via a pre-incorporation method. Physicochemical properties of the OMS-2 and xCu/OMS-2 samples were characterized by means of the XRD, FT-IR, SEM, TG/DTG, ICP-OES, XPS, O-2-TPD, H-2-TPR, and in situ DRIFTS techniques, and their catalytic activities were measured for the oxidation of CO, ethyl acetate, and toluene. The results show that the Cu species were homogeneously dispersed in the tunnel and framework structure of OMS-2. Among all of the samples, 15Cu/OMS-2 sample exhibited the best activities with the T-50% of 65, 165, and 240 degrees C as well as the T-90% of 85, 215, and 290 degrees C for CO, ethyl acetate and toluene oxidation, respectively, which was due to the existence of the Cu species and Mn3+/Mn4+ redox couples, rich oxygen vacancies, good oxygen mobility, low-temperature reducibility, and strong interaction between the Cu species and the OMS-2 support. The reaction mechanisms were also deduced by analyzing the in situ DRIFTS spectra of the 15Cu/OMS-2 sample. The excellent oxygen mobility associated with the electron transfer between Cu species and Mn3+/Mn4+ redox couples might be conducive to the continuous replenishment of active oxygen species and the constantly generated reactant intermediates, thereby increasing the reactant reaction rate.

The Deactivation Mechanism of the Mo-Ce/Zr-PILC Catalyst Induced by Pb for the Selective Catalytic Reduction of NO with NH3 SCIE

摘要 :

As a heavy metal, Pb is one component in coal-fired flue gas and is widely considered to have a strong negative effect on catalyst activity in the selective catalytic reduction of NOx by NH3 (NH3-SCR). In this paper, we investigated the deactivation mechanism of the Mo-Ce/Zr-PILC catalyst induced by Pb in detail. We found that NO conversion over the 3Mo4Ce/Zr-PILC catalyst decreased greatly after the addition of Pb. The more severe deactivation induced by Pb was attributed to low surface area, lower amounts of chemisorbed oxygen species and surface Ce3+, and lower redox ability and surface acidity (especially a low number of Bronsted acid sites). Furthermore, the addition of Pb inhibited the formation of highly active intermediate nitrate species generated on the surface of the catalyst, hence decreasing the NH3-SCR activity.

摘要 :

The poisoning effects of alkali metals (K and Na) and alkaline earth metals (Ca and Mg) on catalytic performance of the 2Nb4Ce/Zr-PILC catalyst for the selective catalytic reduction of NOx with NH3 (NH3-SCR) were investigated, and physicochemical properties of the catalysts were characterized by means of the X-ray diffraction XRD (XRD), Brunner-Emmet-Teller (BET), hydrogen temperature-programmed reduction (H-2-TPR), X-ray Photoelectron Spectroscopy (XPS), ammonia temperature-programmed desorption (NH3-TPD), and in situ diffuse reflectance infrared Fourier transform spectroscopy (in situ DRIFTS) techniques. Doping of M (M = K, Na, Ca, and Mg) deactivated the 2Nb4Ce/Zr-PILC catalyst according to the sequence of 0.8 K > 0.8 Na > 0.8 Ca > 0.8 Mg (M/Ce molar ratio = 0.8). The characterization results showed that the decreases in redox ability, NH3 adsorption, Ce3+/Ce4+ atomic ratio, and amount of the chemisorbed oxygen (O-beta) were the important factors influencing catalytic activities of the alkali metal-and alkaline earth metal-doped samples. Consequently, compared with the Mg- and Ca-doped samples, doping of K caused the 2Nb4Ce/Zr-PILC sample to possess the lowest redox ability, NH3 adsorption, and amount of the O-beta species, which resulted in an obvious deactivation effect.
