Coordinatively unsaturated bismuth sites accelerate in-situ hydrogen peroxide electrochemical formation for efficient butanone oxime synthesis.

ABSTRACT: Selective electrochemical water oxidation via a 2e^- pathway represents a sustainable H₂O₂ electrosynthesis route. However, the low activity and selectivity due to competing 4e^- oxygen evolution and challenges in separating in-situ-generated H₂O₂ for subsequent reactions. Herein, we develop an unsaturated coordinative bismuth-benzene tricarboxylic acid metal-organic framework using a hetero-linker doping strategy. The catalyst demonstrates enhanced performance in selective H₂O₂ synthesis, achieving a low overpotential of 0.98 V and high selectivity with a Faradaic efficiency of 79.1%. The accumulated ~6.17 wt.% H₂O₂ enables an efficient direct conversion of butanone ammoximation to
