Improved mass transport imparts stability and durability in nickel catalysts for urea oxidation

In this issue of Chem Catalysis, J. Zhang et al. report on chromiumdoped nickel hydroxides electrocatalysts that exceed the performances of current state-of-the-art materials in the electro-oxidation of urea in alkaline media and provide a microscopic understanding of their exceptional stability and durability in industrially relevant conditions.
