Studies on Photocatalytic Properties and Antibacterial Activities of Sm3 and Eu3 Influenced Sn1 XZnXO Nanocomposite

Abstract

V newlineAbstract newlineNanocomposites are extensively studied by scientists and engineers to fabricate newlineessential devices associated with cutting-edge technology due to their fascinating and newlineimproved structural, mechanical, thermal, optical, magnetic, catalytic, and antibacterial newlineproperties in comparison to their individual constituents. The best candidates to be used newlinefor preparing novel nanocomposites with significant photoluminescent, photocatalytic, newlineand antibacterial capabilities are transition metal oxide materials. SnO2 and ZnO are newlinewidely investigated as wide band gap semiconductors because of their fundamental newlinescientific interest and prospective applications in the creation of useful devices. ZnO is a newlinesuperb material that finds use in a variety of products, including varistors, enamel newlinecoatings, sunscreen, cements, tyres, food packaging, glue, reagents, copier paper, flame newlineretardants, fungicides, cosmetics, and dental cements. ZnO offers the richest newlinemorphology and most captivating features, including high electron mobility and thermal newlineconductivity values, a wide band gap (3.37 eV), a huge exciton binding energy of 60 newlinemeV, and exceptional chemical and thermal stabilities. SnO2, a versatile semiconductor newlinewith a wide band gap (3.6 eV), is employed in anodes, infrared mirrors, sensors, newlinephotocatalysts, solar panels, fuel cells, transparent conducting electrodes, and more. It is newlinea popular gas sensor for VOC, H2, SO2, C2H2, CO, CH4, NO2, C2H4, and C2H6 with high newlinestability, sensitivity, and speed. It is also efficient in degrading pollutants as a newlinephotocatalyst. Doping of the above metal oxides with suitable elements drastically newlinechanges their structural, optical, magnetic, and electrical properties for practical newlineapplications. Trivalent lanthanides (La, Tb, Er, Eu, Gd, Dy, and Sm) doped metal oxide newlinesemiconducting materials have unique properties and have been extensively studied for newlinecatalysis, optoelectronics, cellular imaging, antibacterial agents, spintronics, and drug newlinedelivery. Lanthanides have electronic configurations compara
