催化剂活性位本质和构效关系的模型催化研究
Toward Understanding the Nature of the Active Sites and Structure-Activity Relationships of Heterogeneous Catalysts by Model Catalysis Studies
摘要
Abstract
Understanding the nature of the active sites and the relationship between the catalyst structure and its performance are fundamental aspects of heterogeneous catalysis. With the development of modern surface science techniques, atomicaly resolved surface structures of heterogeneous catalysts and their properties can be studied with ease. Combined with anin situ high pressure cel, model catalysis studies can provide convincing information about the relationship between the catalyst structure and its performance. In this mini-review, several case studies of model catalysts have been summarized, including those of the active surfaces for CO and alkane oxidation using the Pt group metals as catalysts, the active site of gold nanoparticles for CO oxidation, synergistic effects between VOx and Pt for propane oxidation, promotional effects of Au in Pd-Au catalysts for vinyl acetate synthesis, structure?sensitivity of n?heptane dehydrocyclization on model oxide-supported Pt, as well as several significant improvements of the model catalysis techniques.关键词
