摘要 ：
In this paper, the preparation of V2O5-MoO3/TiO2-expanded graphite (EG) by different methods was investigated to enhance the H2O resistance in SCR reaction. The catalyst with doping of EG by high shear method showed the best SCR performance. BET, TEM, XPS, H-2-TPR, NH3-TPD and FT-IR were used to analyze the physicochemical characteristics of the prepared catalysts. The results indicated that TiO2 particles were distributed uniformly with EG by high shear method, which enhanced the surface area, increased Bronsted and Lewis acid sites and raised the VO2+ and adsorbed oxygen species on the surface. It was found that even with the addition of H2O (20 %) and SO2 at low temperature, the catalyst doping of EG by high shear method maintained about 90 % NO conversion. In addition, in-situ DRIFT spectra results showed that the NH3-SCR reaction over Cat-1 and Cat-2 followed the E-R and L-H mechanism, and the NH3 and NOx adsorbed species on the surface of Cat-2 possessed higher activity in SCR reaction than Cat-1.

摘要 ：
The process of discovering and developing new materials currently requires considerable effort, time, and expense. Machine learning (ML) algorithms can potentially provide quick and accurate methods for screening new materials. In the present work, the features of the metal organic frameworks (MOFs) as a catalyst for fixing carbon dioxide into cyclic carbonate were extracted to build a data set, which were collected from the experimental results of approximately 100 published papers. Classifiers were trained with the data set with various ML algorithms, including support vector machine (SVM), K-nearest neighbor classification (KNN), decision trees (DT), stochastic gradient descent (SGD), and neural networks (NN), to predict the catalytic performance. The ML models were trained on 80% of the data set and then tested on the remaining 20% to predict the carbon dioxide fixation ability. The trained ML model was extended to explore 1311 hypothetical MOFs, and some structures displayed a strong catalytic ability. Finally, the six best metal ions (Mn, V, Cu, Ni, Zr and Y) and four best ligands (tactmb, tdcbpp, TCPP, H3L) were determined. These six metals and four ligands could be combined into 24 MOFs, which are strongly potential catalysts for carbon dioxide fixation. Using machine learning methods can speed up the screening of materials, and this methodology is promising for application not only to MOFs as catalysts but also in many other materials science projects.

摘要 ：
Rare earth metals are strategic resources with potential applications in optics, metallurgy and catalysis. In recent years, single-atom site catalysts (SASCs) have attracted increasing attention owing to their 100% atom efficiency and unique catalytic performances. Over the past decade, rare earth elements, including rare earth metals and their oxides, have shown great potential in SASCs. However, systematic analyses of data are still handful. In this mini-review, the use of rare earth metals and their oxides in SASCs was summarized and the results are discussed. A particular focus was paid to the synthetic strategies, characterization of rare earth-containing SASCs, and applications as catalysis supports, promoters and active sites. Current issues faced by rare-earth metals and their oxides in SASCs, as well as future prospects were also provided. (C) 2020 Chinese Society of Rare Earths. Published by Elsevier B.V.

摘要 ：
Fe-based catalysts have a great potential to be used for selective catalytic reduction (SCR) of NOx with NH3 reaction due to their low cost, nontoxicity and excellent catalytic activity. The aim of this paper is to investigate Ce doping effect on activity of NH3-SCR over the FeOx/TiO2 catalyst. In-situ diffuse reflectance infrared fourier transform (DRIFT) technology was utilized to verify the adsorbed species on the surface of FeOx/TiO2 and FeOx-CeO2/TiO2 catalysts. With respect to the obtained results, among the four catalysts studied, the FeOx-CeO2/TiO2 with the FeOx/CeO2 ratio of 3/8 shows the best NO conversion more than 98% in the temperature range of 230-350 degrees C. The active centers for NH3 adsorption and activation are assigned to Lewis acid sites over the FeOx-CeO2/TiO2 and monodentate nitrates can act as the key intermediate in the NH3-SCR. Moreover, both of Langmuir-Hinshelwood and Eley-Rideal mechanisms are observed over the FeOx-CeO2/TiO2 catalysts in the SCR.
