研究目的
To synthesize high surface area porous graphitic carbon nitrides (g-C3N4) using SBA-15 as a template and hydrochloric acid pretreated melamine, and evaluate their photocatalytic activity toward degradation of rhodamine B (RhB).
研究成果
The synthesized high surface area g-C3N4 showed significantly improved photocatalytic activity for RhB degradation, attributed to enhanced specific surface area and increased separation rate of photogenerated electrons and holes. The CN-3 catalyst demonstrated outstanding stability, making it a promising candidate for environmental remediation applications.
研究不足
The study focuses on the degradation of RhB and may not cover the full range of pollutants. The scalability and cost-effectiveness of the synthesis method for industrial applications are not discussed.
