Ultrafast formation of an FeOOH electrocatalyst on Ni for efficient alkaline water and urea oxidation

We report FeOOH supported on Ni foam which enables highly efficient UOR electrocatalysis and can be readily produced through a hydrolysis reaction. Our developed UOR catalyst as the anode can provide a current density of 200 mA cm −2 at 1.427 V vs. RHE, as well as remarkable operational stability, r...

Summary:We report FeOOH supported on Ni foam which enables highly efficient UOR electrocatalysis and can be readily produced through a hydrolysis reaction. Our developed UOR catalyst as the anode can provide a current density of 200 mA cm −2 at 1.427 V vs. RHE, as well as remarkable operational stability, representing the best yet reported noble metal-free urea electrolyser. The developed UOR electrocatalyst as the anode can provide a current density of 200 mA cm −2 at 1.427 V vs. RHE, as well as remarkable operational stability.
