In this study, silver sulfide nanoparticles (Ag2SNP's) were successfully produced by using fruit extracts of Phyllanthus emblica. UV–vis, FTIR, XRD with SEM and EDX techniques were used for the synthesis process and for characterization of the resulting nanostructures. According to the findings, the fabricated nanostructure had a monoclinic crystal structure, measuring 44 nm in grain size, and its strain was 1.82 × 10−3. As revealed by SEM analysis, the synthesized nanostructure consists of irregular spherical and triangular shapes. The presence of silver (Ag) and sulfur (S) was also confirmed through EDX spectra. Furthermore, Ag2S nanoparticles were tested for their ability to effectively inhibit gram‐positive and gram‐negative bacterial growth. As a result of this study, it was clearly demonstrated that Ag2S nanoparticles possess powerful antibacterial properties, particularly when it came to inhibiting Escherichia coli growth. Ag2S nanoparticles had high total H2O2 and flavonoid concentrations and the greatest overall antioxidant activity, according to the evaluation of antioxidant activity of the samples. The results obtained from the P. emblica fruit extract were followed by those obtained from Ag2S nanoparticles were reported in detail.Research Highlights Innovative Ag2SNP synthesis using Phyllanthus emblica fruit extract. SEM with EDX revealed a monoclinic crystal structure with a grain size of 44 nm and a strain of 1.82 × 10−3. Many of these applications are demonstrated by the potential of Ag2SNPs to treat and combat bacteria, particularly Escherichia coli. A peak at 653 cm−1 indicates the presence of primary sulfide aliphatic C‐S extension vibrations. The abundant H2O2 and NO2 found in P. emblica nanocomposites make them potent antioxidants.

The sulfate radical-based advanced oxidation processes (SR-AOPs) is a promising method for the degradation of pollutants, with the lack of appropriate activation catalysts limiting its application in wastewater treatment. The 1.5BiCoFe LDH was synthesized by coprecipitation method to enhance the activation efficiency of CoFe LDH for peroxydisulfate (PDS), characterized as a complex of Bi2O2CO3 and CoFe LDH. The Bi2O2CO3 imparts high electron transport characteristics, thereby enhancing the activation efficiency of PDS. Comparative analysis with pure CoFe LDH reveals a remarkable increase in reaction rate by approximately 14.66 times. Furthermore, this work proposes an electron transport catalytic mechanism in the reaction system that offers new insights into strengthening PDS activation. Highlights• The 1.5BiCoFe LDH showed excellent activation properties for aniline removal.• The Bi2O2CO3 serves as an electron transfer mediator to promote Co 2+ /Co 3+ and Fe 2+ /Fe 3+ cycles.• SO4 •− , •OH and 1 O2 play a leading role in the degradation of aniline.
