Design and synthesis of high-efficiency and low-cost photocatalysts is essential for converting solar energy into clean hydrogen energy. Herein, we report a novel TiO2 nanocrystal photocatalyst confined by ZIF-67-templated porous CoSx, with conductive Ti3C2 boosting the transport efficiency of the charge carriers. TiO2-CoSx and TiO2-Ti3C2-CoSx exhibit a photocatalytic H-2-production activity 2.8 and 5.8 times larger than that of pristine TiO2, respectively, because of the existence of the highly porous MOF-templated CoSx hydrogen evolution reaction cocatalyst and highly conductive Ti3C2. This study will provide a practical reference for the design and preparation of efficient photocatalysts with high transport and utilization efficiency of charge carriers.
