Multi-shelled hollow spheres of cobalt manganese oxides (CMOs) deposited on Ni foam exhibited superior alkaline electrochemical water oxidation activity and surpassed those of bulk CMO and commercial noble metal-based catalysts. A higher amount of cobalt in the spinel structure resulted in the transformation of the tetragonal to the cubic phase with a decrease in the overpotential of oxygen evolution.
沉积在泡沫镍上的钴锰氧化物（CMOs）多壳空心球表现出优异的碱性电化学水氧化活性，超过了块状CMO和商业贵金属基催化剂。尖晶石结构中较高含量的钴导致四方相转变为立方相，同时析氧过电位降低。
