Constructing core-shell phosphorus doped MnCoO@ZIS for efficient photocatalytic hydrogen production from water splitting.

Rational construction of core@shell heterostructured photocatalysts is the key to realize efficient hydrogen production from water splitting attributing to the accelerated photoinduced charges separation/transfer and enhanced light absorption ability. In this work, two-dimensional (2D) ZnInS (ZIS) nanosheets were in-situ grown on phosphorus doped MnCoO (P-MnCoO) nanospheres to construct P-MnCoO@ZIS heterostructured photocatalysts for efficient photocatalytic hydrogen production. The optimized 6 wt% P-MnCoO@ZIS composite presents remarkable photocatalytic hydrogen evolution rate of 4197 µmol g h (8 times of single ZIS) along with excellent cycling stability, which is comparable to most previous reported ZnInS-based or even noble-metal involved catalysts.
