Abstract

The synthesis of 3D ordered macroporous (3DOM) Ce0.6Zr0.3Y0.1O2 (CZY) is demonstrated by H. Arandiyan, H. Dai, J. Li, and co-workers on page 2366. The 3DOM CZY has mesoporous walls and a high surface area, and incorporates a high dispersion of platinum nanoparticles. A sample with 1.1 wt% Pt shows supercatalytic activity for methane combustion, which is attributed to its larger surface area, higher oxygen adspecies concentration, better low-temperature reducibility, and the unique 3DOM structure.
