Solar-driven reduction of CO2 into renewable carbon forms is considered as an alternative approach to address global warming and the energy crisis but suffers from low efficiency photocatalysts. Herein, a direct Z-Scheme SnS2 /sulfur-bridged covalent triazine frameworks (S-CTFs) photocatalyst (denoted /S-CTFs) was developed, which could efficiently adsorb owing -philic feature S-CTFs promote separation photoinduced electron-hole pairs. Under visible-light irradiation, /S-CTFs exhibited excellent performance for photoreduction, yielding CO CH4 with evolution rates 123.6 43.4 μmol g-1 h-1 , respectively, much better than most catalysts reported date. This inorganic/organic hybrid structure visible-light-driven photoreduction provides new insights designing photocatalysts high solar-to-fuel conversion.
