Synthesis of graphitic carbon nitride-based photocatalysts for hydrogen evolution under visible light

Abstract

The optimal conditions for the synthesis of platinized graphitic carbon nitride (Pt/g-C3N4) have been found. It was investigated as a catalyst for the production of hydrogen from aqueous solutions of triethanolamine (TEOA) under irradiation with visible light. The highest photocatalytic activity of 450 μmol h−1 g−1 and an apparent quantum efficiency of 1.1% were demonstrated by the 1% Pt/g-C3N4 sample prepared from melamine by calcining at 600 °C for 2 h.
