The production of hydrogen from water electrolysis calls for an efficient non-precious-metal catalyst to make the process economically viable because of the high cost and the limited supply of the currently used platinum catalysts. For a catalyst to facilitate the hydrogen evolution reaction (HER), it must combine high durability, high catalytic activity, and high surface area.1-3 Here we present such catalysts made from earth-abundant molybdenum and tungsten. One family of them is molybdenum catalysts made with common, humble soybeans,4 which is composed of a catalytic �-Mo2C phase and an acid-proof ?-Mo2N phase, and drives the HER- with low overpotentials, and is highly durable in a corrosive acidic solution. When supported on graphene sheets, the catalyst exhibits very fast charge transfer kinetics, its performance to be similar to that of Pt catalysts. We will discuss new finding on the related catalysts.The work at BNL is funded by the Division of Chemical Sciences, Geosciences, & Biosciences, Office of Basic Energy Sciences of the U.S. Department of Energy through contract DE-AC02-98CH10886.Reference1.
