A hybrid of CdS/HCa2Nb3O10 ultrathin nanosheets with a tough heterointerface was successfully fabricated. Efficient interfacial charge transfer from CdS to HCa2Nb3O10 nanosheets was achieved to realize the enhanced photocatalytic H2 evolution activity.
Photoinduced in situ synthesis of Cu@Cu2O@C nanostructures with efficient interfacial charge transfer, wide spectral response, and effective protection from photocorrosion by carbon coating, which exhibit efficient and stable hydrogen evolution.
