In-situ granulation synthesis of Ni/NiO nanosheets as high-performance catalysts for alkaline oxygen evolution reaction

摘要

Herein, the Ni(OH)(2) nanosheets are first synthesized, and followed by a thermal treatment strategy to realize the in-situ granulation of Ni/NiO nanosheets to nanoparticles. Benefitting from the unique structure and composition, the overpotential of the as-prepared Ni/NiO-CC/500 can achieve 0.457 V at 10 mA cm(-2). This work can be a reference for designing of two-dimensional (2D) Ni-based materials as an efficient electrocatalyst in the OER and other oxidation reactions.
