Inside Back Cover: Enhancing Photocatalytic Hydrogen Production via the Construction of Robust Multivariate Ti‐MOF/COF Composites (Angew. Chem. Int. Ed. 3/2022)

Photocatalytic H2 production (HER) is one of the most promising technologies for converting solar energy to sustainable and renewable energy. In their Research Article (e202114071), Yi-Fan Chen, Shengqian Ma et al. report a covalent-integrated strategy to construct a new type of MTV-Ti-MOF/COF hybrid photocatalyst, which demonstrates excellent HER performance, highlighting the covalent-integrated approach for effective photocatalytic H2 production.
