Insights into the enhanced photocatalytic and antioxidant properties of novel biogenically synthesised ?-In₂S₃ quantum dots

In the field of nanoscience and nanobiotechnology, use plant extracts in synthesising metal sulphide nanoparticles has lately come to light as an intriguing issue with several benefits over traditional physicochemical methods. Herein, bio-mediated novel ?-In2S3 quantum dots were fabricated using Camellia sinensis var. assamica (tea) leaf extract a stabilising capping agent through facile solvothermal technique evaluate photocatalytic antioxidant characteristics. The prepared green (g-?-In2S3), having bandgap 2.0 eV, employed for degradation three major categories dyes Xanthane (Rhodamine B), Triphenylmethane (Malachite Green), Azo (Biebrich Scarlet). It also showed excellent properties compared standard ascorbic acid pure chemically synthesised ?-In2S3. g-?-In2S3 characterised their crystal structure, morphology, surface functional groups, charge recombination delay, chemical composition XRD, PL, FTIR, UV-DRS, SEM, TEM, XPS analyses. material high crystallinity 77.17%, particle size 6.97 nm, spherical morphology. greenly displayed enhanced performance, indicating that bio-synthesis can be superb method create flexible environmentally friendly goods. About 75.28 ± 1.69%, 72.31 1.43%, 62.21 1.14% Rhodamine B, Malachite Green, Biebrich Scarlet could degraded within 60 min visible irradiation via ?-In2S3/H2O2 system. kinetics mechanism by are discussed. This work highlighted potential light, advanced oxidation process-assisted dyes, outstanding properties.
