Novel Z-scheme BiOCl/g-C3N4 nanocomposite for high performance photocatalytic degradation of organic pollutants and charge carrier dynamics

In this research work, Z scheme BiOCl/g-C₃N₄ nanocomposite was synthesized through hydrothermal process and combined with thermal decomposition method. Numerous characterization techniques were utilized to examine the phase structure, functional groups, morphology, elemental composition, electronic structure and optical behaviour of as synthesized materials. The boosted light absorption capability of BiOCl/g-C₃N₄ nanocomposite which is accredited to the synergetic interaction between the BiOCl and g-C₃N₄ materials. The photocatalytic degradation efficacy of BiOCl/g-C₃N₄ nanocomposite over Rhodamine B (RhB) textile pollutant was exhibited 97 % within 100 min which is higher than the pristine BiOCl material. It’s caused by the active separation, allocation of electrons and holes and reduce the recombination. Five successive recycle process proved the stability and reusability of the material. Finally, This work demonstrates an enriched Z scheme BiOCl/g-C₃N₄ nanocomposite will deliver the impression of construct the Z scheme heterojunction photocatalyst to augment the photocatalytic activity in the occurrence of visible light.
