Ni-based bifunctional electrocatalysts for green hydrogen production coupled with urea oxidation

Replacing the anodic reaction in water electrocatalysis with the thermodynamically favorable urea oxidation reaction (UOR) offers the prospect of a more efficient way of producing hydrogen gas and also the purification of urea -polluted wastewater. The lack of efficient and cheap UOR catalysts is the main obstacle to the spread of this catalytic system. Molybdenum and manganese doped nickel hydroxides were synthetized, characterized and evaluated as UOR catalysts. The Nickel hydroxides were then used to obtain nickel Phosphides that were characterized and evaluated as UOR and hydrogen evolution (HER) catalysts.
