Selective oxidation of aromatic alcohols in the presence of C3N4 photocatalysts derived from the polycondensation of melamine, cyanuric and barbituric acids

Abstract A set of C 3 N 4 samples has been prepared by using melamine, cyanuric acid and barbituric as the precursors. The materials were subjected both to physical chemical characterization used photocatalysts for selective oxidation aromatic alcohols in water suspension under UV visible irradiation. photoactivity versus partial four substituted benzyl was investigated. type position substituents molecule influenced conversion selectivity corresponding aldehyde. presence acids preparation method changed graphitic-C structure, therefore characteristics material ability light activate surface photocatalyst. most active melamine showed a remarkable towards aldehyde even
