Hydroxyl-enriched highly crystalline TiO2 suspensible photocatalyst: facile synthesis and superior H2-generation activity

Abstract

A hydroxyl-enriched highly crystalline TiO₂ suspensible photocatalyst was synthesized via a facile ethanol-controlled hydrolysis and following an in situ crystallization method. In the absence of any cocatalysts, the resultant photocatalyst displayed a clearly higher H₂-evolution rate (622 μmol h⁻¹ g⁻¹) than the well-known commercial P25 TiO₂ (190 μmol h⁻¹ g⁻¹).
