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)33+ 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.
