Abstract:A flake-like alumina with rough surface and small mesopores has been prepared by a hydrothermal method. Remarkably, such alumina was able to stabilize Au nanoparticles, predominantly similar to 2.2 nm in size, even up to an annealing temperature of 700A degrees C. The catalytic activity was tested using the CO oxidation model reaction where a complete conversion of 1% CO in air at 30A degrees C was obtained.
