研究目的
To enhance the photocatalytic performance of Bi3.64Mo0.36O6.55 nanospheres by fabricating heterostructured g-C3N4 quantum dots (CNQDs)/Bi3.64Mo0.36O6.55 nanospheres for the photodegradation of environmental pollutants under visible-light irradiation.
研究成果
The heterostructured CNQDs/Bi3.64Mo0.36O6.55 nanospheres exhibited significantly improved photocatalytic performance for the degradation of Rh B and BPA under visible-light irradiation, attributed to enhanced visible-light absorption, increased BET surface area, and efficient separation of photo-generated charge carriers. The 5 wt% CNQDs/Bi3.64Mo0.36O6.55 sample showed the highest photocatalytic efficiency and good recyclability.
研究不足
The study does not discuss the scalability of the synthesis process or the long-term stability of the photocatalyst under continuous operation. The photocatalytic mechanism, while proposed, could benefit from further experimental validation.
