Title
An efficient polyoxovanadate-catalyzed oxidative mineralization of phenols with 30% aqueous H2O2
Abstract

Catalytic oxidative mineralization of phenols proceeded at 70 °C in the presence of K7NiV13O38 · 16H2O using 30% aqueous hydrogen peroxide as oxidant. At an initial concentration of 0.4 M, nitrophenols and p-chlorophenol were decomposed completely in 15 min, and other phenols were decomposed within two hours. It was disclosed that p-nitrophenol was almost completely mineralized into CO2 and NO3-, accompanied with only trace amount of CO, NO2- and CH3NO2, p-chlorophenol was converted to CO2 and Cl− with trace amount of CO, and phenol and other phenols bearing electron-rich group were converted to CO2 and H2O with trace amount of CO.
