【摘要】：明确催化剂的活性位本质和构建多相催化的结构和反应性能之间的准确关系是催化基础研究的重点,表面科学研究基于丰富的表征测试手段能够较好地在分子原子水平测定表面结构以明确催化剂活性位本质,并通过高压原位反应池测定相关催化反应性能,获得较可靠的催化剂构效关系。本文简要总结了近年来本人参与的几个模型催化研究例子,包括贵金属表面上CO和烷烃催化氧化的活性表面、纳米Au膜的制备和CO氧化的催化活性位、VO_x/Pt(111)上丙烷氧化的协同作用、Au Pd合金上醋酸乙烯酯合成Au的助催化作用、模型氧化物上纳米Pt的庚烷脱氢环化制甲苯的粒径关系等,以及相关模型催化研究技术的进展。
[Abstract]:Determining the nature of the active site of the catalyst and building an accurate relationship between the structure and the reaction performance of the heterogeneous catalyst are the key points of the basic research on catalysis.Surface science research based on abundant characterization methods can better determine the surface structure at the molecular atomic level in order to determine the nature of the active site of the catalyst and determine the catalytic properties of the catalyst by high pressure in situ reaction cell.A reliable structure-activity relationship was obtained.In this paper, we briefly summarize several examples of model catalysis studies I have participated in in recent years, including the catalytic oxidation of CO and alkanes on noble metal surfaces.The synergistic effect of propane oxidation on the catalytic active site of CO oxidation is the synergistic effect of ethylene acetate on au PD alloy on the synthesis of au, and the relationship between the particle size of nano-Pt and heptane dehydrogenation to toluene on the model oxide, and so on.And the research progress of model catalysis.
