Enhanced Photocatalytic Performance of Phosphorus and Molybdenum Co-doped Carbon Nitride for Removal of Organic Pollutants

Strategic Insights -

Researchers at Ningbo University have made a significant breakthrough in the development of advanced photocatalysts for the removal of organic pollutants. By co-doping phosphorus and molybdenum into carbon nitride, they have created a highly efficient and cost-effective solution for degrading Rhodamine B, tetracycline hydrochloride, and methylene blue. The study, published in Surfaces and Interfaces, demonstrates the potential of this novel photocatalyst for sustainable environmental remediation.

Key Takeaways:

  • The researchers synthesized phosphorus and molybdenum co-doped carbon nitride (P-Mo-C3N4) using a simple and scalable wet ball-milling method.
  • The co-doping of P and Mo significantly enhanced the redox capability of g-C3N4, improving its photocatalytic performance by factors of 10.2, 6.5, and 8.6 for Rhodamine B degradation compared to g-C3N4, P-C3N4, and Mo-C3N4, respectively.
  • P-Mo-C3N4 exhibited excellent stability, retaining 90% efficiency after five cycles of degradation.
  • The photocatalyst showed exceptional performances towards tetracycline hydrochloride (TC) and methylene blue (MB), suggesting its potential for real-world applications.
  • The study highlights the cost-effectiveness and eco-friendliness of developing advanced C3N4-based photocatalysts.
  • The research has been peer-reviewed and published in Surfaces and Interfaces, 2025;69.

Statistics:

  • The first-order rate constant (k) of P-Mo-C3N4 for Rhodamine B degradation was 0.1065 min(-1).
  • The transience enhancement factors for P-Mo-C3N4 compared to other photocatalysts were 10.2, 6.5, and 8.6, respectively.
  • The photocatalyst retained 90% efficiency after five cycles of degradation.
  • The research has the potential for real-world applications in removal of organic pollutants.
