Modified Graphene Supported Ruthenium as an Efficient Electrocatalyst for Hydrogen Evolution Reaction in Alkaline Media

With the large consumption of fossil energy, people began spend attention and energy to find and unearth renewable energy, and electrolytic water hydrogen evolution is an ideal scheme. The key to hydrogen production from electrolytic water is to find an appropriate catalyst. Here, we have developed an efficient and durable catalyst by introducing Ruthenium into porous graphene oxide (Ru@PGO), When the current density is 10 mA cm(-2), the the corresponding overpotential and Tafel slope are 40.2 mV and 89.68 mV dec(-1) respectively, and its stability is very excellent. Through theoretical calculation, it is found that ?G(H)* is low, and reveals the effect of pore structure and oxygen introduction on the catalyst. It provides a feasible scheme for the preparation of new catalyst for hydrogen evolution reaction (HER).{GRAPHICAL ABSTRACT}
