“…To remove impurities from water, different methods like ozonation, membrane filtration, adsorption, catalytic reduction, and so forth , have been used. But catalytic reduction has a great impact showing good catalytic activity, affordability, and high thermal stability. − Nanomaterials possess fast adsorption, catalytic activity, and solubility attributed to the large surface area and small size.…”

The present work demonstrates the systematic incorporation of different concentrations of graphene oxide (GO) into a fixed amount of polyacrylic acid (PAA)-doped SnO 2 quantum dots (QDs) through a coprecipitation approach. The research aimed to evaluate the catalytic and antibacterial actions of GO/PAA-SnO 2 QDs. Moreover, optical properties, surface morphologies, crystal structures, elemental compositions, and d-spacings of prepared QDs were examined. X-ray diffraction patterns revealed the tetragonal configuration of SnO 2 , and the crystallinity of QDs was suppressed upon dopants verified by the SAED patterns. Electronic spectra identified the blue shift by incorporating GO and PAA led to a reduction in band gap energy. Fourier transform infrared spectra showed the existence of rotational and vibrational modes associated with the functional groups during the synthesis process. A drastic increase in the catalytic efficacy of QDs was observed in the neutral medium by including dopants, indicating that GO/PAA-SnO 2 is a promising catalyst. GO/PAA-SnO 2 showed strong bactericidal efficacy against Escherichia coli (E. coli) at higher GO concentrations. Molecular docking studies predicted the given nanocomposites, i.e., SnO 2 , PAA-SnO 2 , and GO/PAA-SnO 2 , as potential inhibitors of beta-lactamase E. coli and DNA gyrase E. coli .

“…These discharges contain non-biodegradable, highly toxic colour pigments that are harmful to living organisms [2,3]. Hence, several strategies are adopted to invalidate this serious problem, including ozonation [4], bio adsorption [5], membrane filtration [6], removal by ion exchange [7], adsorption [8], photocatalytic degradation [9,10], catalytic reduction [11], aerobic or biological treatment [12] and coagulation [13]. Other than carcinogenic dyes, heavy metals are also hazardous to human health.…”

Pristine Antimony tungstate nanoparticles prepared via a simple hydrothermal process showcase interesting photocatalytic efficiency, degrading Methylene Blue (MB) completely in 180 min under visible light. In this study, the impact on crystalline quality and related optical properties as well as photocatalytic efficiency of antimony tungstate due to temperature variation during hydrothermal synthesis are explored. While X-ray diffraction (XRD) shows the polycrystalline nature of all synthesized samples, however a systematic increase in crystallite size is revealed by analysing the XRD peak broadening. XRD spectra are further examined by Rietveld analysis showing a change in unit cell volume. Additionally, the overall changes in the corresponding grain size and micro-strain developed in the crystals are determined using the Williamson-Hall plot. Moreover, significant variations in few Raman modes are observed with increasing synthesis temperature. A notable modification in the optical band gap as determined from the absorbance of the UV-Vis spectra is perceived with the change in synthesis temperature within the range of ~2.38-2.57 eV. Further, the photoluminescence measurement indicates that the synthesized antimony tungstate is weak 2 luminescent material with a band-to-band emission at ~468 nm. Finally, photocatalytic efficiencies of the samples are ascertained to change with the synthesis parameter, estimated by decomposing methylene blue (MB), highest degradation rate constant (k) value is observed as 0.015 min -1 for the sample prepared at 180 o C. While the sample with the highest efficiency is also applied for degrading the Rhodamine B (RhB) and Potassium Dichromate (K2Cr2O7) under visible light irradiation.

“…Therefore, it is crucial to clean the waste water before releasing it into the environment. These chemicals are degraded using various conventional waste water treatment techniques like bioadsorption [ 5 ], catalytic reduction [ 6 ], coagulation [ 7 ], membrane filtration [ 8 ], adsorption [ 9 , 10 ], ion exchange removal [ 11 , 12 ], photocatalytic degradation [ 13 , 14 ], ozonation [ 15 ] and biological/aerobic treatment [ 16 ]. Over the past few years, photodegradation of pollutants has become incredibly popular [ 17 , 18 , 19 , 20 , 21 ].…”
