Abstract:

Titanium dioxide(TiO2) materials have attracted much attention due to their low cost, high natural abundance, environmental friendliness, good chemical stability and excellent optical properties. Among them, ordered mesoporous TiO2 materials have been widely used in physics, chemistry, materials science due to their high surface area, large pore volume, adjustable pore structure and morphology etc. In this article, we summarize the synthesis of ordered mesoporous TiO2 by reasonably controlling the rate of hydrolysis and crosslinking of titanium precursors. Furthermore, the application of mesoporous TiO2 in the photocatalytic splitting of water to produce hydrogen is also discussed. Finally the challenges in this field are proposed.

Key words: Mesoporous titanium dioxide, Photocatalytic hydrogen production, Soft template, Hard template
