Highly Active Photocatalyst of Cu(2)O/TiO(2) Octahedron for Hydrogen Generation

[Image: see text] Heterojunction catalysts are attracting attention in the field of photocatalytic hydrogen generation for their effective light utilization and charge separation personalities. In this work, we report a simple and low-cost two-step solvothermal method for synthesizing Cu(2)O/TiO(2) heterojunction catalysts with an octahedral morphology and a mean particle size of about 30 nm. It is found that the introduction of Cu(2)O astonishingly enhances the photocatalytic performance of TiO(2). Under the condition of methanol acting as a sacrificial agent, the heterojunction with 0.19% Cu species shows an optimal hydrogen generation rate of 24.83 mmol g(–1) h(–1), which is nearly 3 orders of magnitude higher than that of the pristine TiO(2) catalyst.
