摘要
金(Au)的催化作用已成为催化领域的前沿研究课题。本文综述了近年来采用不同方法制备介孔二氧化硅(MCM-41,MCM-48,SBA-15)负载的纳米Au催化剂及其在CO低温氧化、环己烯加氢和环己烷氧化等反应中的催化作用。讨论了影响纳米Au催化剂活性的相关因素,包括载体的种类、表面性质、Au纳米颗粒的尺寸、分散度以及稳定性等。最后对各种制备纳米Au的方法进行了总结。
Gold catalysis is becoming the frontier research field in catalysis chemistry. The present article intends to review recent progress in the fabrication of Au nanoparticles supported on mesoporous silica （MCM-41, MCM-48, and particularly SBA-15） and their catalytic applications in low-temperature CO oxidation, cyclohexene hydrogenation, and cyclohexane oxidation. The latest knowledge on the factors determining the characteristics and catalytic performance of Au nanoparticles, such as the type and surface property of support, the size, dispersion, location, and stability of Au nanoparticles, has been summarized and the related discussion is given.
