We report the transfer of H-atoms from a reduced polyoxovanadate alkoxide [ⁿOct₄N][V₆O₆(OH₂)(OMe)₁₂] via concerted proton–electron transfer. Oxygen reduction is compared between bridging and terminal O–H bonds revealing similar mechanisms, providing new insight to design criteria for metal-oxide electrocatalysts that faciliate oxygen reduction by concerted-proton electron transfer.

多氧钒酸盐-醇盐簇上的 V(III) 水合物通过质子耦合电子转移还原 O2

我们报道了通过协同质子-电子转移从还原的多氧钒酸醇盐 [ ⁿ Oct ₄ N][V ₆ O ₆ (OH ₂ )(OMe) ₁₂ ]转移氢原子。比较桥接键和末端 O-H 键之间的氧还原，揭示了相似的机制，为通过协同质子电子转移促进氧还原的金属氧化物电催化剂的设计标准提供了新的见解。
