Chemical upcycling of Ni from electroplating wastewater into a well-defined catalyst for electrooxidation of glycerol to formate

exhibited good electrooxidation of glycerol to formate with a selectivity of 96.4%, surpassing a vast majority of previously reported electrocatalysts. Therefore, our findings not only provide an efficient strategy for removing Ni from electroless electroplating wastewater but also advance the upcycling of Ni waste into a functional material for the electrocatalytic synthesis of value-added products.
