Implementation of non-precious electrocatalysts is key-enabling for water electrolysis to relieve challenges in energy and environmental sustainability. We recently demonstrate an interfacial confinement of Ni-V2O3 in molten salts to enhance the electrocatalytic hydrogen evolution. Self-supporting Ni-V2O3 electrodes consisting of nanostrip-like V2O3 perpendicularly anchored on Ni meshes are constructed via the electrochemical reduction of soluble NaVO3 in molten salts. The synergy between Ni and V2O3 promotes the activation of H2O and combination of H* to form H2. The strategy herein can provide not only the activity improvement of Ni towards electrocatalytic hydrogen evolution but also value-added processing of vanadium slag wastes. The above results are now accepted for publication in Journal of Energy Chemistry as a cover paper.
