摘要 ：
The sustainable development of tungsten and molybdenum resources requires a new clean and recyclable separation technology. This work proposes a recyclable clean separation technology of tungsten and molybdenum with a porous amine resin. The resin was well prepared by assembling amine groups on trioctylamine (TOA) and the porous resin matrix D301 by the dipping method. Here, pH 7.8, temperature 25 & DEG;C, and reaction time 240 min was used as optimum condition, resulting in the highest sorption capacity 236 mg g(-1), and it has a good cycle performance, exhibiting a retention rate of 90% after five cycles. Experimental spectroscopy combined theoretical calculation confirmed that this sustainable sorption behavior is substantially related to the amine functional groups on the resin. Experimental spectroscopy illustrated that the Cl- ions in the amine resin and the MoS(4)(2-& nbsp;)ions were subjected to ion exchange. Theoretical investigations further confirm that the sorption site is at the N atoms, the sorption behavior is chemical binding with the binding energy -0.055 Ha, and the bonding method is the s orbit of the N atoms in the amine resin hybridized with the s orbit of the S atoms in the amine resin. Owing to such an excellent performance in the selective sorption of molybdenum from the tungstate solution, the amine resin is greatly promising in the tungsten and molybdenum waste recovery field.

摘要 ：
The effects of alloying element Al on microstructure, tensile properties and aqueous corrosion behavior of Cantor alloy are investigated. The results show that the crystal structure of Cantor alloy does not change with the addition of 6 at.% Al, and the alloy still maintains a single FCC structure. The two alloys have typical dendritic morphology and obvious dendritic segregation. The yield strength increases by 24% and reaches 219 MPa without obvious deterioration of ductility through addition of Al. Although both Cantor and Cantor-Al alloys exhibit pitting corrosion in 3.5 wt.% NaCl solution due to non-uniform distribution of elements, addition of Al improves the corrosion resistance of Cantor alloy through formation of protective Al2O3 scale.

摘要 ：
This study examined the possibility of deep significance for the reduction of low-valence tungsten to inhibit disproportionation reactions in various molten alkali chlorides. Electrolysis and electrochemical tests of tungsten carbide were carried out in molten LiCl, LiCl-KCl, NaCl-KCl, NaCl-CsCl, and KCl-CsCl. One finding was that the reduction valence of tungsten ions decreased as the radius of the solvent alkali ion increased. This phenomenon may be viewed from the dissolution of tungsten carbide and the existence and deposition of tungsten ions. The mechanism of tungsten ion reduction and the stable configuration of tungsten ion groups were confirmed via a detailed study of the computational calculation. The increase in the radius of the solvent alkali ion was conducive to the dissolution of tungsten from tungsten carbide in the form of low valence state. Other results also indicated that W(ii) ion groups first deposited on the cathode. They had the advantages of smaller coordination numbers and faster diffusion combined. Morphological and composition analysis results of the products are also presented.

摘要 ：
Tungsten trioxide has attracted extensive attention for photocatalytic applications owing to its unique structure and intrinsic merits; however, the small specific surface area and rapid electron-hole recombination still limit its adsorption and photocatalytic efficiency. Herein, WO3 center dot 0.33H(2)O/g-C3N4 nanocomposite photocatalysts were designed and constructed using a facile low temperature hydrothermal method. The interaction between 1D WO3 center dot 0.33H(2)O nanorods and 2D g-C3N4 nanosheets produces a heterojunction with enhanced adsorption and photocatalytic degradation performance towards methylene blue pollutant. It is found that the synergistic effect of the surface charge and specific surface area significantly enhances the adsorption capacity which can be up to 23 times higher than that of WO3 center dot 0.33H(2)O, and the optimal photocatalytic activity is 3.67 and 1.70 times higher than that of pristine WO3 center dot 0.33H(2)O and g-C3N4, respectively.

摘要 ：
A facile microwave-assisted precipitation method was used to synthesize hierarchical WO3 center dot H2O using urea as the shape control agent. The morphologies of WO3 center dot H2O can be controlled by tuning the concentration of urea. For model dyes of methylene blue (MB), rhodamine B and methyl orange which possess different sizes and charges in solution, WO3 center dot H2O exhibits excellent selective adsorption capacity, especially for MB. The adsorption kinetic and adsorption isotherm could be described by the pseudo-second-order kinetic model and Langmuir adsorption isotherm model, respectively. The experimental results indicate that the maximum uptake capacity of the flower-like WO3 center dot H2O for MB is 478.34 mg g(-1) in neutral pH, which is higher than many literature reports. In addition, the adsorption mechanism of WO3 center dot H2O is proposed. [GRAPHICS] .

摘要 ：
The leaching mechanism of the spent selective catalytic reduction (SCR) catalyst was investigated by density functional theory (DFT) calculations and experiments. Three models, namely V2O5/TiO2, WO3-V2O5/TiO2, and WO3/TiO2, were created to simulate the spent SCR catalyst. Interaction between the surface clusters and the leaching agents of NaOH, H2SO4, HCl and HNO3 was investigated by DFT calculations. The adsorption site was determined through electrostatic potential and adsorption energy. The calculations showed that NaOH tended to be adsorbed on V and W atoms. H2SO4, HCl and HNO3 tended to be adsorbed on specific O atoms. H2SO4 dissociated on all three models, HCl dissociated on V2O5/TiO2 and WO3-V2O5/TiO2, while HNO(3 )dissociated only on V2O5/TiO2. The order of leaching ability among leaching agents was NaOH > H2SO4 > HCl > HNO3. Ex-periments showed that the leaching ratios of V and W in NaOH solution were 82.4% and 54.3%. In acid solution, the leaching ratio of V was 69.0% for H2SO4, 52.5% for HCl, and 42.2% for HNO3, while W was hardly leached out. After acid leaching, the change in the TiO2 lattice parameter was greater than that after alkaline leaching. The experimental results were found to be consistent with the calculations.

摘要 ：
This paper reports a novel method for rapid atomic-level reconstruction of tungsten carbide (WC) using Na2CO3- containing molten salt. Herein, WC was used as consumable anode and Na2CO3 was active species on WC anode and carbon donor. Thermodynamic calculations were used to verify the feasibility of this electrolytic method for reconstructing WC. Experimental results showed that the addition of Na2CO3 significantly enhanced dissolution efficiency of WC. Therefore, more tungsten (W) source was supplied. Electrochemical analysis demonstrated that Na2CO3 also supplied carbon by two-step reduction process, which led to the formation of WC. These experiments confirmed that cathode product was converted from W to WC by the introduction of Na2CO3 additive into molten salt. WC phase started to form at cell voltages above 2.2 V. In initial stage of reaction, carbonate was preferentially reduced in cathode region to form amorphous C. As the reaction proceeded, W ions migrated from anode and began to participate in reduction process, forming W. Finally, W was transformed to WC by carbonization process.
