Borate Buffer as a Key Player in Cu‐Based Homogeneous Electrocatalytic Water Oxidation
Guilin Ruan, Natalia Fridman, Galia Maayan
Abstract
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 −1 . 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.
