MoS2 nanoflower-decorated reduced graphene oxide paper for high-performance hydrogen evolution reaction

Abstract

A facile, one-pot solvothermal method is developed to synthesize MoS2 nanoflowers (MoS2NFs) coated on reduced graphene oxide (rGO) paper. The resulting MoS2NF/rGO paper serves as a freestanding, flexible and durable working electrode for hydrogen evolution reaction (HER), exhibiting an overpotential lowered to −0.19 V with a Tafel slope of ∼95 mV per decade.
