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 at 1.427 V vs. RHE, as well as remarkable operational stability, representing the best yet reported noble metal-free urea electrolyser.
我们报道了负载在泡沫镍上的FeOOH，它能够实现高效的尿素氧化反应（UOR）电催化，并且可以通过水解反应轻松制备。我们开发的用于UOR的催化剂作为阳极，在相对于可逆氢电极（RHE）为1.427 V的电压下可提供200 mA cm的电流密度，以及出色的运行稳定性，是目前报道的性能最佳的无贵金属尿素电解槽。
