Renewable Hydrogen

Nickel-molybdenum alloy nanoparticles as low-cost and earth abundant electrocatalysts for water splitting

Background

Increasing energy demands paired with growing environmental concerns are challenging the current paradigms of power sources and production. Renewable hydrogen is being explored as an energy carrier and chemical reagent to supplement and wean the usage of fossil fuels. Current methods to produce hydrogen include electrochemical water splitting using renewable electricity or direct water splitting via photocatalysis. However, many of the current electro- and photocatalysts for water splitting incorporate costly platinum group metals (PGM) for the hydrogen evolution reaction (HER) as the primary or secondary catalysts. Researchers at VCU have developed an alternative to PGM electrocatalysts using earth-abundant low-cost elements.
