Electrochemical water splitting, which converts directly electrical energy into chemical energy, has attracted extensive attention worldwide as a crucial strategy of energy storage and conversion. In theory, oxygen evolution reaction (OER) is a vital factor in controlling water splitting efficiency due to its sluggish kinetics. Accordingly, a facile solvothermal approach was utilized to synthesize hollow Ni0.85Se porous materials embedded by carbon materials (Ni0.85Se/C), serving as catalysts of OER. In contrast to the unsupported Ni0.85Se and RuO2, the obtained Ni0.85Se/C catalyst has better electrochemical performances owing to the addition of carbon and the presence of hollow structure. In addition, the decent durability of Ni0.85Se/C provides the possibility for the practical use.
