Enhancing the reactivity of nickel(<scp>ii</scp>) in hydrogen evolution reactions (HERs) by β-hydrogenation of porphyrinoid ligands

Abstract

with TFA, which is in line with the electrocatalysis and computational results. Thus, such subtle structural changes inducing the distinctive reactivity of Ni(ii) not only test the fundamental understanding of natural Ni tetrapyrroles but also provide a valuable clue to design metal porphyrinoid catalysts.
