Abstract

The photoluminescence (PL) property of CeO2/g-C3N4 mixed samples have been studied in recent years, but it is not attractive due to their lower PL emission. In this paper, a simple mixing-calcinations method was used to prepare CeO2/g-C3N4 mixed particles. In this paper, CeO2 particles were synthesized at two different temperatures (120 and 140 °C) by two-step method. The g-C3N4 powders were prepared by heating urea directly. Then, the two products were mixed together and annealed at 300 °C for 1 h by a simple mixing-calcinations method. It was found that the spindle and fascicular shapes of CeO2 were surrounded by lamellar g-C3N4 with porous surface. The strong emission and emission peaks shifting happened to CeO2/g-C3N4 particles, in which CeO2 was prepared at 120 °C, due to the mutual synergistic effect of CeO2 and g-C3N4.
