Abstract

The utilization of a novel heterogeneous photocatalyst for the photodegradation of organic pollutants under visible light is regarded as a significant and indispensable approach for ensuring a sustainable and safe environment, both in laboratory settings and on a larger scale. Therefore, a novel nanocomposite Cu-TiO2@g-C3N4 consisting of mesoporous pure graphite g-C3N4 and Cu-TiO2 was synthesized using a sol-gel technique combined with ultrasonic treatment. The crystal structure of Cu-TiO2 was conclusively verified using the X-ray diffraction pattern and incorporated into the g-C3N4 structure. The Cu-TiO2 nanoparticles were observed to have a spherical shape based on the SEM images and were evenly distributed throughout the g-C3N4 nanosheets. The efficacy of Cu-TiO2@g-C3N4 nanocomposites as a novel photocatalyst for degrading MB dye under visible light was investigated. Cu-TiO2@g-C3N4 had a synergistic effect on the photocatalytic activity associated with the degradation of MB dye.
