Few-Layered MoWS Hollow Nanospheres on NiS Nanorod Heterostructure as Robust Electrocatalysts for Overall Water Splitting.

Owing to unique optical, electronic, and catalytic properties, MoS have received increasing interest in electrochemical water splitting. Herein, few-layered MoWS hollow nanospheres-modified NiS heterostructures are prepared through a facile hydrothermal method to further enhance the electrocatalytic performance of MoS. The doping of W element optimizes the electronic structure of MoS@NiS thus improving the conductivity and charge-transfer ability of MoS@NiS.
