Among a variety of characterization techniques, multi-wavelength Raman spectroscopy, combining resonance Raman and non-resonance Raman with different excitation wavelengths, has recently emerged as a particularly powerful tool in not only identifying but also quantifying the structure of supported metal oxide clusters. In this review, we make use of two supported vanadia systems, VOx<\/i><\/sub>/SiO2<\/sub> and VOx<\/i><\/sub>/CeO2<\/sub>, as examples to showcase how one can employ this technique to investigate the heterogeneous structure of active oxide clusters and to understand the complex interaction between the oxide clusters and the support. The qualitative and quantitative structural information gained from the multi-wavelength Raman spectroscopy can be utilized to provide fundamental insights for designing more efficient supported metal oxide catalysts.","articleNo":"20141001","authorCnList":["吴自力"],"authorEnList":["Zili Wu"],"authorList":["吴自力"],"authors":"吴自力","authorsCn":"吴自力","authorsEn":"Zili Wu","categoryName":"综述","categoryNameCn":"综述","categoryNameEn":"Review","citation":"吴自力. 负载氧化钒催化剂的多波长拉曼光谱研究：结构识别和定量. 催化学报, 2014, 35(10): 1591-1608. doi: 10.1016/S1872-2067(14)60082-6.","citationCn":"吴自力. 负载氧化钒催化剂的多波长拉曼光谱研究：结构识别和定量. 催化学报, 2014, 35(10): 1591-1608. doi: 10.1016/S1872-2067(14)60082-6.","citationEn":"吴自力.

In this review, we focus on the influence of the heterojunction on the performance of semiconductor photocatalysts, including TiO2<\/sub>-based, ZnO-based, and Ag-based semiconductor photocatalysts. We also investigate fabrication methods for heterojunctions and attempt to understand the mechanisms behind photocatalysis.

The current understanding and enlightenment from foundation and development of ammonia synthesis catalyst are reviewed, and its future and facing new challenge remained today are expected. Catalytic ammonia synthesis technology has played a central role in the development of the chemical industry during the 20th century. During 100 years, ammonia synthesis catalyst has come through diversified seedtime such as Fe3<\/sub>O4<\/sub>-based iron catalysts, Fe1-x<\/i><\/sub>O-based iron catalysts, ruthenium-based catalysts, and discovery of a Co-Mo-N system. Often new techniques, methods, and theories of catalysis have initially been developed and applied in connection with studies of this system. Similarly, new discoveries in the field of ammonia synthesis have been extended to other fields of catalysis. There is no other practically relevant reaction that leads to such a close interconnection between theory, model catalysis, and experiment as the high-pressure synthesis of ammonia. Catalytic synthesis ammonia reaction is yet a perfect model system for academic research in the field of heterogeneous catalysis. Understanding the mechanism and the translation of the knowledge into technical perfection has become a fundamental criterion for scientific development in catalysis research. The never-ending story has not ended yet. In addition to questions about the elementary steps of the reaction and the importance of the real structure and subnitrides for the catalyst efficiency, as well as the wide-open question about new catalyst materials, there are also different challenges thrown down by theory for the experimentalist in the prediction of a biomimetic ammonia-synthesis path at room temperature and atmospheric pressure including electrocatalysis, photocatalysis and biomimetic nitrogen fixation.","articleNo":"20141003","authorCnList":["刘化章"],"authorEnList":["Huazhang Liu"],"authorList":["刘化章"],"authors":"刘化章","authorsCn":"刘化章","authorsEn":"Huazhang Liu","categoryName":"综述","categoryNameCn":"综述","categoryNameEn":"Review","citation":"刘化章. 氨合成催化剂100年：实践、启迪和挑战. 催化学报, 2014, 35(10): 1619-1640. doi: 10.1016/S1872-2067(14)60118-2.","citationCn":"刘化章. 氨合成催化剂100年：实践、启迪和挑战. 催化学报, 2014, 35(10): 1619-1640. doi: 10.1016/S1872-2067(14)60118-2.","citationEn":"刘化章.

The results showed that the enzyme loading and initial activity of the immobilized PGA decreased with increasing amounts of epoxy groups. These observations were due to a decrease in the pore size of the mesoporous silica as well as an increase in the hydrophobicity of the silica surface. However, an appropriate amount of epoxy groups on the CIMS support was found to improve the operational stability of the immobilized PGA. This improvement was the result of increased interactions between the epoxy functionalized CIMS support and the PGA.","articleNo":"20141012","authorCnList":["詹望成"," 吕勇军"," 杨玲"," 郭杨龙"," 王艳芹"," 郭耘"," 卢冠忠"],"authorEnList":["Wangcheng Zhan"," Yongjun Lü"," Ling Yang"," Yanglong Guo"," Yanqin Wang"," Yun Guo"," Guanzhong Lu"],"authorList":["詹望成"," 吕勇军"," 杨玲"," 郭杨龙"," 王艳芹"," 郭耘"," 卢冠忠"],"authors":"詹望成, 吕勇军, 杨玲, 郭杨龙, 王艳芹, 郭耘, 卢冠忠","authorsCn":"詹望成, 吕勇军, 杨玲, 郭杨龙, 王艳芹, 郭耘, 卢冠忠","authorsEn":"Wangcheng Zhan, Yongjun Lü, Ling Yang, Yanglong Guo, Yanqin Wang, Yun Guo, Guanzhong Lu","categoryName":"论文","categoryNameCn":"论文","categoryNameEn":"Article","citation":"詹望成, 吕勇军, 杨玲, 郭杨龙, 王艳芹, 郭耘, 卢冠忠. 乙烯基Ia3d介孔硅分子筛的环氧化及其固定化青霉素酰化酶. 催化学报, 2014, 35(10): 1709-1715. doi: 10.1016/S1872-2067(14)60156-X.","citationCn":"詹望成, 吕勇军, 杨玲, 郭杨龙, 王艳芹, 郭耘, 卢冠忠. 乙烯基Ia3d介孔硅分子筛的环氧化及其固定化青霉素酰化酶. 催化学报, 2014, 35(10): 1709-1715. doi: 10.1016/S1872-2067(14)60156-X.","citationEn":"詹望成, 吕勇军, 杨玲, 郭杨龙, 王艳芹, 郭耘, 卢冠忠.

The effects of elemental substitution in the LaCoO3<\/sub> perovskite were studied, and the catalytic performance and primary stability of the hydrogen production from SRE were investigated. In the highly substituted samples, only the Ce-doped sample was isolated as the pure perovskite phase. The presence of a Co3<\/sub>O4<\/sub> phase in the Ca-doped or Sr-doped samples was beneficial for the reduction of the active Co component, while Sr-doped or Ce-doped samples showed good activity and stability. The sample incorporating Sr demonstrated better catalytic performance than those of other samples.","articleNo":"20141018","authorCnList":["马飞"," 丁振武"," 储伟"," 郝世雄"," 齐涛"],"authorEnList":["Fei Ma"," Zhenwu Ding"," Wei Chu"," Shixiong Hao"," Tao Qi"],"authorList":["马飞"," 丁振武"," 储伟"," 郝世雄"," 齐涛"],"authors":"马飞, 丁振武, 储伟, 郝世雄, 齐涛","authorsCn":"马飞, 丁振武, 储伟, 郝世雄, 齐涛","authorsEn":"Fei Ma, Zhenwu Ding, Wei Chu, Shixiong Hao, Tao Qi","categoryName":"论文","categoryNameCn":"论文","categoryNameEn":"Article","citation":"马飞, 丁振武, 储伟, 郝世雄, 齐涛.
