BiVO4 nanoparticles and Ag nanoparticles co-decorated with tubular carbon nitride: A ternary heterostructure photocatalyst for degradation of organic pollutants in water

Photocatalytic technology represents an effective and cost-efficient approach to the degradation of organic pollutants. This paper presents an investigation into the degradation ability of ms -BVO/TCN/Ag composite for organic pollutants at different ratios. The 7.5% ms -BVO/TCN/Ag sample was observed to exhibit the most effective degradation performance under visible light irradiation, with degradation rates of 83.12% and 84.45% for TC and DEP in 120 min. This is attribute to the distinctive tubular configuration of TCN, which enhances the number of reactive sites. The addition of Ag nanoparticles to TCN expands the light absorption spectrum of TCN through the surface plasmon resonance (SPR) effect. Furthermore, the construction of Z-scheme heterojunctions between TCN/Ag and ms -BVO preserves the robust redox capabilities of these components while mitigating the rapid complexation of photogenerated electron pairs. This paper presents a novel strategy and approach for the further construction of heterojunctions, based on the morphological control of carbon nitride.
