Ni(OH)2 Derived from NiS2 Induced by Reflux Playing Three Roles for Hydrogen/Oxygen Evolution Reaction

文献摘要：

Developing efficient and promising non-noble catalysts for oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)is vital but still a huge challenge for the clean energy system.Herein,we have integrated the active components for OER(Ni(OH)2)and HER(NiS2 and Ni(OH)2)into Ni(OH)2@NiS2 heterostructures by a facile reflux method.The in-situ formed Ni(OH)2 thin layer is coated on the surface of hollow NiS2 nanosphere.The uniform Ni(OH)2@NiS2 hollow sphere pro-cesses enlarge the electrochemically active specific surface area and en-hance the intrinsic activity compared to NiS2 precursor,which affords a current density of 10 mA cm-2 at the overpotential of 309 mV and 100 mA cm-2 at 359 mV for OER.Meanwhile,Ni(OH)2@NiS2 can reach 10 mA cm-2 at 233 mV for HER,superior to pure NiS2.The enhanced performance can be attributed to the synergy between Ni(OH)2 and NiS2.Specifically,Ni(OH)2 has three functions for water splitting:providing active sites for hydrogen adsorption and hydroxyl group desorption and working as real OER active sites.Moreover,Ni(OH)2@NiS2 displays great stability for OER(50 h)and HER(30 h).
