Abstract
En 中文
A sunlight-activated photocatalyst that is environmentally friendly and harmless to the surrounding environment could serve as an appropriate choice for wastewater treatment approaches. In the present research, we strengthened TiO2 by employing Carbon Quantum Dots (CQDs) in order to enhance their photocatalytic efficiency and circumvent their efficiency restrictions. Upon thoroughly investigating the TiO2@CQDs hybrids' morphological characteristics, framework, and other capabilities, it became obvious that the CQDs and TiO2 were both properly merged. When the TiO(2)CQDs nanocomposite material was implemented in lieu of unaltered CQDs, the photodegradation of Malachite Green dye (MGD) under solar radiation displayed a spike in reaction rate. The nanocomposite's potential to capture sunlight was substantially enhanced by doping, which additionally improved interfacial charge transfer and segregation. The involvement of active species in the decay of MGD was determined as well by a radical scavenging test. The key attributes that increased the appealing factor of CQDs and TiO2@CQDs nanocomposite with regard to photocatalytic potential were their economic fabrication and environmentally benign reagents.
