用于丙烯环氧化反应的金催化剂

摘要

Direct gaseous-phase epoxidation of propylene over nanogold catalysts in the co-presence of H2 and O2 is the major research point for the application of gold catalysts. The influence of the support, nanogold particles, and synergistic effect between the supports and nanogold particles on the catalytic performance of gold catalysts for propylene epoxidation was reviewed. The technical problems and research direction of propylene epoxidation in vapor phase in the future were put forward.%以氢气和氧气混合气为氧源的丙烯环氧化反应是金催化剂应用研究的主要反应.综述了金催化剂在丙烯环氧化反应中的载体材料影响、金纳米粒子作用以及金纳米粒子与载体之间的协同作用对催化性能的影响,提出气相直接氧化丙烯生产环氧丙烷尚待解决的技术问题和相应的研究新亮点.
