Cobalt and iron phosphates with modulated compositions and phases as efficient electrocatalysts for alkaline seawater oxidation
Chandni Das, Poulomi Roy
Abstract
An electrocatalyst which is suitable for use in both fresh water and real seawater electrolysis is very uncommon. In this work, we have developed a series of iron-tuned cobalt phosphates and cobalt-tuned iron phosphate solid solutions as electrocatalysts exhibiting excellent OER activities not only in freshwater but also in alkaline real seawater with a faradaic efficiency of 95%.
