Microwave assisted hydrothermal synthesis of Bi2O3 /Ag2O heterostructures with highly enhanced photocatalysis and their biological interest

Abstract

A methodological analysis is made in the rational synthesis of the Bi2O3/Ag2O nanostructure with significant application, possessing substantial electron-hole recombination acting as solar catalysts through powerful and modest hydrothermal technique. The composite Bi2O3/Ag2O is intermediary for single step Methyl Red (MR) dye photocatalytic degradation. Under the impact of solar irradiation heavy metals like, Lead (Pb) are also removed by the synthesized material surface influence of sunlight. Anti-cancer activity upon Colon cancer cells (HCT116) is achieved with excellent cell viability and IC50 value. The research work or the present study found an excellent and efficient design of photocatalyst as an eco-friendly and biomedical approach.

Evaluation of Cytotoxic Effect in Ag/ZnO Nanocomposites on Human Myelogenous Leukaemia

“…The peaks at 31.4 o , 34 o , 35.9 o , 47.2 o , 56.2 o , 66 o , 67.6 o and 68.8 o correspond to the hexagonal wurtzite structure of Zinc Oxide (ZnO), as evidenced by a strong match with JCPDS Card No. 36-1451 [16]. These results affirm the crystalline nature of the ZnO phase in the nanocomposite.…”

“…Additionally, a peak at 1381 cm −1 was identified as the bending vibration of C-H in the methyl group, while a minor peak at 880 cm −1 was attributed to the C-H out-of-plane bending from the alkene group. The absorption bands at 419, 484, and 573 cm−1 were assigned to the stretching modes of M-O (M = Ag & Zn) bonds [16].…”

“…The remarkable efficiency of Ag/ZnO nanocomposites is attributed to their plasmonic properties and interfacial electron exchange processes. Moreover, in comparison to pure ZnO nanoparticles, the effectiveness of Ag/ZnO nanocomposites has been evaluated for their heightened release of silver and zinc ions in aqueous solutions, increased stability, enhanced reusability, and prolonged bactericidal effects [16][17][18][19][20].…”
