Light-driven hydrogen evolution with a nickel thiosemicarbazone redox catalyst featuring Ni⋯H interactions under basic conditions

Abstract: The photocatalytic hydrogen evolution inspired by the highly evolved, finely tuned molecular photosynthetic systems in nature represents an important process in sustainable solar energy conversion for the near future. By incorporating a phosphine donor within a thiosemicarbazone moiety, a new proton reduction catalyst NiÀthioP, featuring NiÁ Á ÁH interactions was synthesized and structurally characterized. Single crystal structure analysis revealed that the C-S, C-N and N-N bond lengths were all within the nor… Show more

“…[6,[11][12][13][14] Metal complexes based on thiosemicarbazone ligands are now emerging asan ew class of electrocatalyst for HER. [14][15][16][17] These complexes presents ome interesting features that are relevant for electrocatalytic protonreduction:the thiosemicarbazone ligand has already been shown to be redox active, [14,[18][19][20][21] whereas the presence of S-donors and severalNatoms allows for protonation of the ligand and can serve as proton relays. [5,22] Based on these two features, we can define three types of HER reactivity:1 )ligand-assistedm etal-centered reactivity, [14] 2) ligand-centered reactivity, [16] and 3) metal-assisted ligand-centered reactivity.…”

“…The lower overpotential in methanol is consistent with outer-coordination sphere proton shuttling, 32 which facilitates ligand protonation prior to electrochemical reduction, as previously suggested with thiosemicarbazide complexes. 32, 33 The HER TOF of ZnL is substantially higher than other proposed ligand-centered catalysts, suggesting H 2 L itself may also demonstrate catalytic activity.…”
