Organic pollutants in wastewater are the biggest problem facing the world today due to population growth, rapid increase in industrialization, urbanization, and technological advancement. There have been numerous attempts to use conventional wastewater treatment techniques to address the issue of worldwide water contamination. However, conventional wastewater treatment has a number of shortcomings, including high operating costs, low efficiency, difficult preparation, fast recombination of charge carriers, generation of secondary waste, and limited light absorption. Therefore, plasmonic-based heterojunction photocatalysts have attracted much attention as a promising method to reduce organic pollutant problems in water due to their excellent efficiency, low operating cost, ease of fabrication, and environmental friendliness. In addition, plasmonic-based heterojunction photocatalysts contain a local surface plasmon resonance that enhances the performance of photocatalysts by improving light absorption and separation of photoexcited charge carriers. This review summarizes the major plasmonic effects in photocatalysts, including hot electron, local field effect, and photothermal effect, and explains the plasmonic-based heterojunction photocatalysts with five junction systems for the degradation of pollutants. Recent work on the development of plasmonic-based heterojunction photocatalysts for the degradation of various organic pollutants in wastewater is also discussed. Lastly, the conclusions and challenges are briefly described and the direction of future development of heterojunction photocatalysts with plasmonic materials is explored. This review could serve as a guide for the understanding, investigation, and construction of plasmonic-based heterojunction photocatalysts for various organic pollutants degradation. Graphical abstract Herein, the plasmonic effects in photocatalysts, such as hot electrons, local field effect, and photothermal effect, as well as the plasmonic-based heterojunction photocatalysts with five junction systems for the degradation of pollutants are explained. Recent work on plasmonic-based heterojunction photocatalysts for the degradation of various organic pollutants in wastewater such as dyes, pesticides, phenols, and antibiotics is discussed. Challenges and future developments are also described.

“…In response to this high demand and supply chain of agriculture-based products, it is quite impossible to ban the use of pesticides globally. Thus, efforts have been made to eliminate pesticide residues through many conventional and new techniques over recent years to resolve this problem [23][24][25] . However, given the need for sustainable development, a green way to degrade pesticide residual should be prioritized.…”

Pesticides are widely used to prevent bug infestation in agricultural crops and to get rid of other pests and disease-carrying creatures including mice, rats, ticks, and mosquitoes from various environment and h In response to this environmental and human health hazard, a dire need for remediation has emerged in the last few decades. Green approaches for the remediation of pesticides can boost sustainable development. A biomimetic approach for degradation of pesticides can have high potential to generate ripples of positive outcomes. Biomimetic catalysts are synthetic chemical molecules which have been inspired by natural processes to mimic their structural and functional properties. This short review concisely focuses on the synthesis of various biomimetic catalysts including metal-based materials, carbon-based materials and others. In this context, recent advances achieved by such biomimetic catalysts for the degradation of pesticides have been covered. It highlights the importance of adopting a biomimetic approach as it provides a green and efficient method for pesticides degradation

“…For instance, Vaya and Surolia [27] have written a review mainly focusing on non‐biogenic semiconductor‐based for pesticide degradation and mineralization in aqueous environments. de Oliveira's team [23] study primarily reviewed the combined effect involving plasmonic and semiconductor non‐biogenic NPs in degrading pesticides under photo influence, while Shanaah et al [28] primarily focused only on the utilization of non‐biogenic metal oxides and their composites for both photocatalytic degradation and adsorptive removal of pesticides. Secondly, some reviews extended the focus of the study to the degradation of only one type of organophosphorus using metal oxide NPs.…”

The use of efficacious and cost‐effective pesticides (OP and OC) has undoubtedly proven to be a blessing and a baron because these pesticides are safeguarding the world from food insecurity. Unfortunately, their presence in aquatic bodies brings about an upsurge in water pollution. Amazingly, the photocatalytic degradation approach utilizing biogenic nanoparticles (BNPs) is a trendy state‐of‐the‐art approach and has been established to be a sustainable methodology for the complete mineralization of contaminants into harmless molecules. Thus, this work holistically explores the use of BNPs for photocatalytic degradation of OP and OC. Based on the review, it was found that the least amount of time needed for degradation was less than 5 minutes, while the maximum degradation efficiency was >80 %. The dominant radicals participating in the degradation are ⋅OH and O2⋅ and this radical dominance was enhanced by the oxygenated functional groups present in the biogenic entities employed for the biosynthesis of BNPs. The photocatalytic degradation data fits the pseudo‐first‐order and Langmuir isotherm models (R2 > 0.9), which indicates that the main adsorption mechanisms involved during electron‐hole pair formation and photocatalytic degradation are physisorption and monolayer at the surface of the BNPs. BNPs can sustain a >80 % degradation efficiency for approximately 5 cycles and are reusable for up to 8 cycles. It was also revealed that plants constitute 80 % of the engaged biogenic entities for BNP synthesis. Ultimately, this work offers novel avenues and future research hotspots that might accelerate the use of BNPs for sustainable agricultural and wastewater management practices.
