摘要

This article covers the importance of Andean Aj?′/Chilli (Capsicum baccatum L.) mediated synthesis of gold nanoparticles (AuNPs), which favors for green chemistry and escape us from the use of hazardous chemicals. UV–visible spectroscopy was used to monitor the quantitative formation of AuNPs. Further, as synthesized AuNPs were characterized using Transmission electron microscopy, Dynamic Light Scattering, and X-ray diffraction. It produced spherical AuNPs at λ _(max)?=?540?nm of average size 23.9?±?9.7?nm without any aggregation. Aj?′ extract (aq) was the good reducing and capping agent in terms of conversion to Au~(3+) to AuNPs. The synthesized AuNPs, also enhancing the photocatalytic degradation of methylene blue (50%, k ?=?1.9585?×?10~(?3)?min~(?1)) under direct solar light irradiation. In addition, the experimental approach is benign, ecofriendly, and inexpensive for industrial-scale production of nanoparticles using Aji extract as natural bioreductant.
