摘要：
In this paper, we report a procedure using soft/hard dual templates to produce gamma-alumina with hierarchically ordered mesopores and macropores (HOMA). Polystyrene spheres colloidal crystals and block copolymer are sequentially used as templates for ordered macropores and mesopores, respectively. Both macropores and mesopores are ordered pores. The wall of cage-like 500 nm macropores is composed of ordered mesopores of 3.6 nm, and the walls of mesopores are composed of gamma-alumina. When loaded with Pt nanoparticles for CO oxidation, Pt/HOMA catalyst shows excellent catalytic properties. (C) 2010 Elsevier Inc. All rights reserved.
