The design of 3D artificial leaves with spatially separated active sites for H2 and O2 generation and their application to water splitting†
Abstract
In this study, we report a facile, environmentally friendly sol–gel route for the preparation of 3D TiO2 artificial leaves with spatially separated active sites for H2 and O2 generation. The unique CoOx/TiO2/Pt architecture has multiple merits and exhibits enhanced photocatalytic activity for hydrogen production.
