Conclusion
In summary, we combined co-catalyst modification and morphological modification to synthesized a new Mn0.05Cd0.98S/NiSe2composite catalyst by a facile method. The cubic NiSe2could provide extensive surface for Mn0.05Cd0.95S nanoparticles anchoring, effectively preventing the occurrence of Mn0.05Cd0.98S nanoparticle agglomeration. Secondly, the modification of NiSe2 co-catalyst further improves the light absorption intensity and electrochemical performance of MCS, thereby improving hydrogen production activity. In result, the Mn0.05Cd0.98S/NiSe2composite catalyst proved an excellent hydrogen producing activity. The maximum hydrogen production of 713.78 μmol is procured over Mn0.05Cd0.98S/NiSe2-10 wt% composite, which is 7.5 times than that of the pure Mn0.05Cd0.95S. In this work, we designed a series of novel 0D/3D nanohybrids of Mn0.05Cd0.95S/NiSe2photocatalysts, which could beneficial for practical applications.
