Oxygen evolution from water by use of earth-abundant element-based catalysts is crucial for mass solar fuel production. In this report, a mesoporous cobalt oxide with an ultrahigh surface area (up to 250 m2·g–1) has been fabricated through Mg substitution in the mesoporous Co3O4 spinel, followed by...
