Abstract
Oxygen Evolution Reaction Article 2200473 by Chao Huang and co-workers demonstrates the preparation of highly dispersive Co(OH)2 nanosheets vertically grown on V2O5 nanoflowers (Co(OH)2/V2O5) at room temperature. The V5+ of V2O5 can oxidize Co2+ of Co(OH)2 into Co3+, resulting in a strong electronic interaction between V and Co favorable to the OER process, delivering a low overpotential of 320 mV at a current density of 10 mA cm−2.
