摘要
Abstract Hydrogen production from photocatalysis via the usage of multicomponent photocatalysts represents a promising pathway for carbon peaking and carbon neutrality, owing to their structural advantages in dealing with the three crucial processes in photocatalysis, namely, light harvesting, charge transfer, and surface redox reactions. We demonstrate the fabrication of a MOF‐based multicomponent photocatalyst, denoted as semiconductor/MOF/cocatalyst, by a one‐pot electrochemical synthetic route. The as‐fabricated multicomponent photocatalyst has a clean interface among the components, leading to close connections that contribute to high‐quality heterojunction and facilitate photogenerated charge transfer and separation, thereby the efficient hydrogen evolution. The hydrogen production rate of the resultant ZrO 2 /Zr‐MOF/Pt is 1327 μmol ⋅ g −1 ⋅ h −1 , which is much higher than that of ZrO 2 /Zr‐MOF (15 μmol ⋅ g −1 ⋅ h −1 ) and pure Zr‐MOF (10.1 μmol ⋅ g −1 ⋅ h −1 ), as well as the photodeposited‐Pt products ZrO 2 /Zr‐MOF/Pt PD (287 μmol ⋅ g −1 ⋅ h −1 ) and Zr‐MOF/Pt PD (192 μmol ⋅ g −1 ⋅ h −1 ) obtained by the step‐wise synthetic approach. The work gives a good inspiration for the rational design and construction of MOF‐based multicomponent photocatalysts through the one‐pot electrosynthesis.
