Title
A micellar polyoxoperoxometalate [C16H33N(CH3)3]7[PW10Ti2O38(O2)2]: A highly efficient and stable catalyst for air oxidation of thiocyanate under room conditions
Abstract

A micellar polyoxometalate catalyst [C16H33N(CH3)3]7[PW10Ti2O38(O2)2] was prepared and used for catalytic wet air oxidation of thiocyanate (SCN−). The 97.6% removal efficiency was obtained with oxygen and under room conditions. And the oxidation of SCN− was achieved completely leading degradation products SO42−, HCO3−, NH4+ and NO3− within 150 min. The leaching test showed that the POM micellar catalyst had excellent stability and could be used as heterogeneous catalyst for about five times.
