Urea Electrooxidation In article number 2303300, Yan Qing, Yiqiang Wu, and co‐workers develop an ultrafine homologous Ni2P–Co2P heterostructure via a topological transformation strategy. The Co incorporation reduces the generation potential of the surface reconstructive active species and optimizes the absorption/desorption energy of the intermediates, achieving a superior urea electrooxidation activity, promising for use in simultaneous urea‐enriched wastewater treatment and energ...
