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.

In this work, the author developed Ca4Fe9O17/biochar (CFB) via a green method through a facile co-precipitation procedure involving egg shells as calcium precursor and investigating its performance in single as well as binary solution of methylene blue (MB) and rhodamine B (RhB). The CFB nanocomposite was characterized by XRD, SEM, TEM, XPS, Raman, FTIR, BET, and VSM. ESR studies show the presence of hydroxyl (·OH) and superoxide (O2·¯) radicals, which are primary radical species for pollutant degradation. The average crystalline size of CFB nanocomposites was found to be 32.992 nm using XRD, whereas TEM analysis indicates a particle diameter of 35–36 nm. The degradation efficacy of MB and RhB dyes was achieved at 99.2% and 98.6%, respectively, in a single solution, whereas 99.4% and 99.2%, respectively, in a binary solution within 36 min. Additionally, an iron cluster was formed during the degradation process of MB dye. The degradation of organic contaminants and generation of iron clusters from the degraded dye products were both expedited by the remarkable extension effect of the Ca4Fe9O17 in the CFB nanocomposites. The three processes were achieved using CFB nanocomposite: (1) the advanced oxidation process; (2) degradation of MB and RhB dye in single as well as binary solution with enhanced efficiency, (3) the production of the iron cluster from degraded products. Thus, these three steps constitute a smart and sustainable way that leads to an effective effluent water treatment system and the generation of iron clusters preventing secondary pollution.
