Abstract

The study involved synthesizing ZnO nanoparticles co-doped with Co, Ag, and Cu, labeled as Zn1-3xCoxAgxCuxO (x = 0.00, 0.01, 0.02, 0.03), using a low-temperature co-precipitation process. Spectroscopic techniques confirmed the successful incorporation of these elements into the ZnO lattice. Structural analysis showed a hexagonal wurtzite crystal structure with microstructural changes across the samples. Lattice property alterations indicated the inclusion of Co2+, Ag1+, and Cu2+ ions, leading to a crystallite size increase from 25.3 nm to 36.7 nm. FESEM displayed spherical and hexagonal structures. UV-Vis spectroscopy revealed a bandgap reduction from 3.22 eV to 2.92 eV as doping increased, attributed to the Burstein-Moss effect. Raman analysis demonstrated shifts in the E2(High) mode due to impurities. The photocatalytic activity of Zn0.94Co0.02Ag0.02Cu0.02O was 2.2 times higher than pure ZnO for RhB, with hydroxyls radicals as key agents. This material showed exeptional reusability and stability. The nanoparticles also effectively degraded Methyl Orange, Congo Red, and Phenol. The study suggests that co-doping with Co, Ag, and Cu is an effective approach for tuning the ZnO bandgap, highlighting its potential for optoelectronics, spintronics, and photocatalysis, and paving the way for advanced optical and photonic applications.

期刊介绍: Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
