WebLayered cobalt hydroxides are cost-efficient electrocatalysts for oxygen evolution reaction (OER) in the field of energy conversion. Herein, we developed a facile synthesis method of 3d transition-metal-doped α-Co(OH)2 nanomaterials mediated with ammonia in water–methanol at room temperature. The doping of Cu2+ and Ni2+ leads to flower-like … WebHerein, a superior OER catalyst of Fe substituted α-Co (OH) 2 (α-Co 1−m Fe m (OH) 2) has been synthesized by taking advantage of the large layered structure and good conductivity of α-Co (OH) 2, in conjunction with the rich redox properties and abundance of Fe.
