説明
<jats:title>Abstract</jats:title><jats:p>Although tremendous effort has been directed to synthesizing advanced TiO<jats:sub>2</jats:sub>, it remains difficult to obtain TiO<jats:sub>2</jats:sub> exhibiting a photocatalytic efficiency higher than that of P25, a benchmark photocatalyst. P25 is composed of anatase, rutile, and amorphous TiO<jats:sub>2</jats:sub> particles, and photoexcited electron transfer and subsequent charge separation at the anatase–rutile particle interfaces explain its high photocatalytic efficiency. Herein, we report on a facile and rational hydrothermal treatment of P25 to selectively convert the amorphous component into crystalline TiO<jats:sub>2</jats:sub>, which is deposited between the original anatase and rutile particles to increase the particle interfaces and thus enhance charge separation. This process produces a new TiO<jats:sub>2</jats:sub> exhibiting a considerably enhanced photocatalytic efficiency. This method of synthesizing this TiO<jats:sub>2</jats:sub>, inspired by a recently burgeoning zeolite design, promises to make TiO<jats:sub>2</jats:sub> applications more feasible and effective.</jats:p>
