In this article, an exquisite flexible hybrid MoS/graphene free-standing electrocatalyst paper was fabricated by a one-step solvothermal process. The assembled MoS/graphene catalysts exhibit significantly enhanced electrocatalytic activity and cycling stability towards the splitting of water in acidic solution. Furthermore, a strategic balance of abundant active sites at the edge of the S-Mo-S layers with efficient electron transfer in the MoS/graphene hybrid catalyst plays a key role in controlling the electrochemical performance of the MoS nanosheets. Most importantly, the hybrid MoS/graphene nanosheet paper shows excellent flexibility and high electrocatalytic performance under the various bending states. This work demonstrates an opportunity for the development of flexible electrocatalysts, which have potential applications in renewable energy conversion and energy storage systems.
