Development of novel Nd 2 O 3 doped Ag nanocomposite for the catalytic degradation of methylene blue and biological studies

Abstract

Our study focuses on optical behavior, methylene blue (MB) dye degradation potential of pure Neodymium oxide (Nd2O3 NPs), and Silver (Ag)/Neodymium oxide (Nd2O3) nano-composite, besides demonstrating their antibacterial performance in the resolve of silver and trioxide mineral interaction with different types of bacterial species. For illustration, S.aureus, and E.Coli give a significant response with clear enlargement of inhibition zone under Ag NPs adding. S.aureus inhibition area widened from 9.3 ± 0.5 mm for pure Neodymium oxide (Nd2O3) to 16.7 ± 0.4 mm for Ag/Nd2O3 nano-composite, while Escherichia coli inhibition zones jumped from 8.8 ± 0.4 mm for Neodymium oxide to15.9 ± 0.3 mm for Ag/ Nd2O3. Additionally, generally optical behavior shows clear band-gap narrowing with merging Ag NPs, which enhances boosting electronic localization. That direct and direct transitions dropped from (6.7 to 6.1) and (5.2 to 2.9 e.V), respectively. Regarding the MB degradation, Mixed System Ag/ Nd2O3 shows more efficient Methylene blue degradation than pure Nd2O3 in that the MB concentration fell to almost half of its starting point at 150 minutes, while pure Nd2O3 reached 33% after 150 minutes. Moreover, TEM displays the studied compositions microstructures confirming the good distribution of Ag NPs (average size 9.2 nm) upon Nd2O3. The results interpretations boost usage of such composites in sensors industries, and water treatment.
