Preparation and Photocatalysis of Ordered Mesoporous Mg-Ta Mixed Oxide

Abstract
An ordered mesoporous Mg-Ta mixed oxide (123 m2·g-1 BET surface area, ca. 5.0 nm mesopore size and 3.6 nm wall thickness), which was stable after calcination at 500 °C for 30 h, showed stable and high photo-catalytic activity for overall water decomposition.
