Two-step coupled photoelectrochemical chlorination and oxygenation of C(sp³)-H bonds mediated by chlorine radicals over a modified BiVO₄ photoanode.

ABSTRACT: Photoelectrochemical (PEC) cells are emerging tools for fine chemical synthesis, but often suffer from low solar-to-product conversion efficiency, especially in energy-demanding reactant activation. Herein, we report chlorination and oxygenation of energy-demanding C(sp³)-H bonds using a two-step coupled PEC cell, avoiding the direct generation of high-energy chlorine radicals (Cl˙). The photoanode consists of a BiVO₄ semiconductor modified with TiO₂ and a CoNi₂O _x chlorine evolution reaction (CER) catalyst. Under 1 sun illumination, the BiVO₄/TiO₂/CoNi₂O _x photoanode showed a photocurrent density of 2.9 mA cm^-2 for CER at 0.8 V vs. the reversible hydrogen elec
