多相催化加氢反应中H2异裂解离的研究进展
Research progress of H2 heterolysis in heterogeneous catalytic hydrogenation
摘要
Abstract
Heterogeneous catalytic hydrogenation is an important approach for preparation of high-value-added fuels and chemicals,while the processes of H2 heterolysis and chemical properties of generated hydrides(M—Hδ-)are closely related to hydrogenation activity and selectivity.However,the complex surface structure of heterogeneous catalysts,which leads to a diversity of H2 heterolysis process and M—Hδ-chemical properties,poses a great challenge in understanding the regulation of H2 heterolysis and M—Hδ-chemical properties on the mechanism of hydrogenation reactions.The mechanism of H2 heterolysis and the chemical properties of M—Hδ-were reviewed,and the characterization techniques commonly used to detect M—Hδ-were presented and their advantages and disadvantages were analyzed.The internal relationship between H2 heterolysis and the structure of active site of catalysts in different heterogeneous catalytic systems,such as metal-supported catalysts,metal oxide catalysts and anionic hybrid metal catalysts,as well as the optimization of the performance of hydrogenation reaction were discussed,and effective strategies to regulate H2 heterolysis were proposed.Finally,the main challenges in the study of H2 heterolysis and M—Hδ-were summarized and future development directions were outlined.关键词
