Chinese scientists have recently achieved the direct synthesis of high-purity benzaldehyde chemicals from the selective electrooxidation of benzyl alcohol. The organic-solid-water (OSW) three-phase reaction system has shown particular advantages in reducing ohmic losses and simplifying product separation and purification processes compared to conventional H-type electrochemical cells. Electrocatalysis in aqueous electrolyte has been recognized as a green method for organic redox reactions, since
