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.
