Photoelectrochemical Synthesis of Adipic Acid by Selective Oxidation of Cyclohexanone (Adv. Energy Mater. 11/2025)

Photoelectrochemical Syntheses

In article number 2405052, Ruikang Zhang, Zhenhua Li, Mingfei Shao, and co-workers first reported a photoelectrochemical strategy to achieve the selective oxidation of cyclohexanone to adipic acid using a cooperative Ni(OH)₂/TiO₂ photoanode with H₂O as oxygen source. The new Ni^2+δ─OH* reactive center was in situ generated on a Ni(OH)₂/TiO₂ photoanode under illumination, which significantly facilitates the activation of C_α─H and the subsequent C─C cleavage to produce adipic acid.
