Details
This project synthesized bi-metallic nanoparticle-decorated photocatalysts using ultrasonic irradiation to degrade aflatoxin B1 (AFB1). The material demonstrated 100% degradation efficiency of AFB1 in household wastewater within 2 minutes under visible light.
Photocatalytic materials decorated with bi-metallic nanoparticles (Bi-Metallic NPs/ photocatalyst) were synthesized for the degradation of aflatoxin B1 using ultrasonic irradiation.
- Characterization: The materials were analyzed using TEM, XPS, XRD, FT-IR, zeta potential analyzer, and UV-visible spectrophotometer.
- Performance: The catalyst achieved 100% degradation of AFB1 in household wastewater within 2 minutes under visible light.
- Mechanism: The superior performance is attributed to a highly porous structure, increased specific surface area, and a reduced electron-hole recombination rate.
Objective
The objectives include developing bi-metallic nanoparticle-decorated photocatalysts, evaluating their degradation efficiency for AFB1 under visible light, and studying the underlying mechanisms for environmental application.
