Abstract

Abstract : A nanosized Mn oxide/boron nitride composite is reported as a catalyst for water oxidation. Abstract : Herein, a nanosized Mn oxide/boron nitride composite is reported as a catalyst for water oxidation. This study is interesting because nanosized boron nitride is one of the most stable and inert compounds and can form a new composite with Mn oxides. The composite was synthesized using a straightforward and simple procedure and characterized, showing that the composite is a supported Mn(iii, iv ) oxide on boron nitride. The water-oxidizing activity of the composite was studied in the presence of cerium(iv ) ammonium nitrate and photoproduced Ru(bpy)3 3+ as oxidants. The optimized catalyst calcined at 200–300 °C showed a turnover frequency of 0.15 (mmolO2 /s −1 molMn −1 ) in the presence of cerium(iv ) ammonium nitrate.
