Abstract

Borate buffer was found to have both structural and functional roles within a low-cost tri-copper electrocatalyst for homogeneous water oxidation that exhibits a high turnover frequency of 310 s . The borate buffer was shown to facilitate the catalytic activity by both bridging the three Cu ions and participating in O-O bond formation. Phosphate and acetate buffers did not show such roles, making borate a unique player in this catalytic system.

摘要

硼酸缓冲剂在一种低成本三铜均相水氧化电催化剂中具有结构和功能作用，其具有 310 s 的高周转频率。硼酸缓冲剂通过桥连三个 Cu 离子和参与 O-O 键形成来促进催化活性。磷酸盐和乙酸盐缓冲剂没有表现出这种作用，使硼酸成为该催化体系中的独特参与者。
