catalyst to reduce the overpotential of nickel deposition [32, 33]. To verify the effect of boric acid on current efficiency in the electrolytic membrane reactor, experiments were performed by varying boric... of hydrogen and decreases the evolution of H2 [34]. The nickel borate also acts as a homogeneous catalyst to reduce the overpotential for nickel deposition. The increase of current efficiency leads......
