A comprehensive review on photocatalytic degradation of agro-organochlorine pollutants using multifunctional metal oxide and supported and doped metal oxide nanoarchitecture materials

The environment and public health are seriously threatened by the rising incidence of organochlorine pollutants (OCPs) in aquatic environments. In response, photocatalytic degradation has emerged as a viable and sustainable method for getting rid of these dangerous contaminants. This study offers a thorough examination of the most recent developments in photocatalytic degradation approaches, with a specific focus on multifunctional metal oxide nanoparticles (MONPs). Through a critical appraisal of relevant literature, the review elucidates the underlying mechanisms involved in the photocatalytic degradation of OCPs and evaluates the performance of various metal oxide nanoarchitecture materials. The review also includes an in-depth exploration of the regenerability and recyclability of spent MONPs. Future research directions in the area of circular economy and cost analysis were also provided to help upcoming researchers. In conclusion, this review consolidates the current knowledge on the photocatalytic degradation of emerging OCPs, providing valuable insights into the application of MOPs, and contributing to the development of sustainable and efficient strategies for mitigating the environmental damage of OCPs to aid the actualization of Sustainable Development Goals 3, 6, and 14.
