| Abstract |
Graphitic carbon nitride (g-C3N4) is a promising metal-free, low cost, and environment-friendly photocatalysts well suited for degradation of organic pollutants. Herein, we investigate the photocatalytic performance of g-C3N4–based materials and correlate it with their structural properties, using three different precursors (dicyandiamide, melamine, and urea) and two heating processes (direct heating at 550 oC and sequential heating at 300 and 550 oC) to produce the above photocatalysts. We further demonstrate that sequential heating produces photocatalysts with grain sizes and activities larger than those of the catalysts produced by direct heating and that the use of urea as a precursor affords photocatalysts with larger surface areas, allowing efficient rhodamine B degradation under visible light. |
