Twinned zinc cadmium sulfide (ZnxCd1-xS) has been extensively studied to achieve efficient Cr(VI) reduction and H2 production under light irradiation due its inherent homojunctions. However, long-distance migration of charge carriers relatively low CB level inevitably cause photocatalytic ability. Herein, we developed a DMF-involved one-step solvothermal strategy introduce N heteroatoms into Zn0.67Cd0.33S crystals incorporated with dopant-induced S vacancies. Due the synergetic promotion elevated conduction band strong interactants aggregation, recombination behavior was effectively impeded, resulting increased photocurrent density (~2.4 times) electron (~2.8 times), as well higher photo-reducing potential. The optimal NZCS-10 demonstrated superior efficiency 99.06% within 30 min, rendered ca. 5.8- 7.6-fold enhancement for evolution rate alkaline acidic conditions, respectively. This study provided universal gaining highly reductive transition metal sulfides more active sites.
