“…Upon going through deeply, it was observed that the technique or nanomaterials used for degradation have many issues, such as utilization of UV‐ light source, the origin of secondary pollutants, and time‐consuming. Parveen et al 67 have reported adsorption of ES on Fe 2 (MoO 4 ) 3 nanoparticles. The mineralization of many pollutants under similar conditions was also reported 68 .…”

Herein, inexpensive and eco‐friendly approach for the green synthesis of silver‐doped metal hexacyanoferrates (Ag@MHCFs) nanocomposite using green tea extract has been reported. Silver‐doped MHCF nanocatalysts were used to photo‐degradation endocrine disruptor pesticides, namely endosulfan (ES) and atrazine (AT), from water under direct Sunlight. Spectroscopic and electron microscopic techniques confirmed the successful synthesis of nanomaterials. Ag@FeHCF observed maximum degradation efficiency due to their high surface area (89.3 m2g−1), significant zeta potential (−43.4 mV), lower band gap (1.5 eV), and low photoluminescence intensity as compared to other Ag doped MHCFs. Best degradation results showed with concentration amount (5 mg L−1), dose (20 mg of ES; 15 mg of AT), at neutral pH under sunlight irradiation. Degradation up to 98% for ES and 96% for AT was reported. The degradation ensued by Langmuir adsorption and first‐order kinetics. GC–MS analysis showed the degradation of pesticides into CO2, H2O, and harmless minor metabolites under Sunlight. Ag@FeHCF have indicated high reusability (n = 10), ensuring their charge separation, stability, and sustainability. Ag@MHCF nanoparticles may show as substitute catalysts for industrial use with a fervent scope.

“…EDX spectroscopy results in Fig.4 bshow that a peak around 5.5 keV indicates Ag and O are dominant elements in the sample. The strong signal energy peak for Ag atoms around 5.5 keV is typical for absorbing metallic and Ag nanocrystals onto EC[9]. A single solid energy peak indicated the purity of Ag in the sample, whereas other study reports stated the presence of C (2.20 %) and O (22.04 %)[10] with synthesised AgNPs.…”

Water hyacinth, commonly known as Eichhornia crassipes, is a deadly aquatic weed known for causing environmental hazards, which include blocking river waters and canals and clogging irrigation and hydropower systems chemically. It also reduces the bio-oxygen demand (BOD) of the aquatic in the river, making the river unfriendly to the animals around it. Thus, many countries are trying their best for the removal of this weed using various methods. Green synthesis is an excellent tool utilised in the synthesis process of AgNPs. Water pollution and environmental pollution caused by organophosphate and organochlorine pesticides have threatened living organisms, animals, and humans; hence, there is a need to synthesise multifunctional materials that can be used to degrade various pollutants. This study aimed to evaluate the effectiveness of biosynthesised Silver and Iron nanoparticles for catalytic degradation of organochlorine and organophosphate pesticides. The sample was collected in Hayin Gada Mubi Road Girei Local Government area of Adamawa State with latitude 9 0 17 1 16 11 N and Longitude 12 0 26 1 48 11 East.Silver and Iron Nanoparticles were synthesised using Eichhornia crassipes (water hyacinth extract) and characterised using XRD, SEM, TEM, SEM.EDX, UV-Spectrophotometer and FTIR. SEM/EDX, TEM, XRD, FTIR confirmed the formation of Silver and Iron Nano particles. UV-Spectrophotometer gave optical information whereby an excitation at 410 nm for silver and Iron 358 nm. Research on the photocatalytic degradation rate of Organochlorine and Organophosphate using varied concentrations of 25/75, 50/50 and 75/25 for AgNPs in the photocatalysis process was the primary goal of the present study. The influence of the main operating parameters such as photocatalyst concentration, Pesticide concentration, pH and effect of time. The result revealed that AgNPs have high and significant photocatalytic efficiency in organophosphate, and organochlorine has less degradation activity. In conclusion, the research aimed to achieve AgNPs have higher activity against organophosphate (Sniper) than Organochlorine (DDT).

“…The presence of POPs in textile effluents leads to a series of negative effects on the ecology [20][21][22]. Insecticides are used in households, agriculture, medical industry, etc., which enter into water sources, causing toxicity in the aquatic and terrestrial organisms, leading to alteration of the ecosystem, in addition to human health [23,24]. Photocatalytic degradation of organic pollutants by metal oxides has gained attention among researchers due to its efficacy in attacking contaminants of the environment [20,25,26].…”

Prewetting Induced Hydrophilicity to Augment Photocatalytic Activity of Nanocalcite @ Polyester Fabric

To eliminate imidacloprid insecticide from wastewater, nanocalcite was grafted onto the surface of pretreated polyester fabric. The process of seeding was followed by the low temperature hydrothermal method for the growth of nanocalcite for the functionalization of fabric. The goal of this study was to improve the hydrophilicity of the nanocalcite photocatalyst that had been grafted onto the surface of polyester fabric (PF) using acidic and basic prewetting techniques. The morphological characteristics, crystalline nature, surface charge density, functional groups of surface-modified nanocalcite @ PF were determined via SEM, XRD, FTIR, and Zeta potential (ZP), respectively. Characterization results critically disclosed surface roughness due to excessive induction of hydroxyl groups, rhombohedral crystal structure, and high charge density (0.721 mS/cm). Moreover, contact angle of nanocalcite @ PF was calculated to be 137.54° while after acidic and basic prewetting, it was reduced to 87.17° and 48.19°. Similarly, bandgap of the as fabricated nanocalcite was found to be 3.5 eV, while basic prewetted PF showed a reduction in band gap (2.9 eV). The solar photocatalytic mineralization of imidacloprid as a probe pollutant was used to assess the improvement in photocatalytic activity of nanocalcite @ PF after prewetting. Response surface methodology was used to statistically optimize the solar exposure time, concentration of the oxidant, and initial pH of the reaction mixture. Maximum solar photocatalytic degradation of the imidacloprid was achieved by basic prewetted nanocalcite @ PF (up to 91.49%), which was superior to acidic prewetted fabric and as-fabricated nanocalcite @ PF. Furthermore, HPLC and FTIR findings further indicated that imidacloprid was decomposed vastly to harmless species by basic prewetted nanocalcite @ PF.
