“…Generally, nanomaterials have a specific field of application due to their unique properties, such as copper nanoparticles (Cu NPs) for high thermal conductivity, high-strength alloys, and antibacterial and antiviral compounds (Aguilar et al, 2019 ; Akhavan and Ghaderi, 2010 ; Das Jana et al, 2021 ; Le et al, 2023 ; Lei et al, 2013 ). Cu NPs are also widely used in a variety of fields, including photochemical catalysis, electronics, optics, biosensing, and gas sensors (Akhavan and Ghaderi, 2011 ; Khodashenas and Ghorbani, 2014 ; Patil et al, 2015 ; Tadjarodi et al, 2015 ).…”

Waste printed circuit boards (WPCBs) contain a plethora of valuable metals, considered an attractive secondary resource. In the current research, a hydrometallurgical process combined ammonia/ammonium chloride leaching and reduction (using L-ascorbic acid) to recover copper and its oxide (CuO) as nanosized particles from WPCBs was investigated. The results of leaching indicated that 96.7% of copper could be recovered at a temperature of 35 °C for a leaching duration of 2 h with ammonium chloride and ammonia concentration of 2 mol/L at a solid:liquid ratio of 1:10 g/cm3. The synthesized particles exhibit spherical and distorted sphere morphology with average particle size of 460 nm and 50 nm for Cu and CuO NPs, respectively. The antibacterial activity of Cu, CuO, and a (1:1) blend of both (Cu/CuO) has been examined against five different bacterial and fungal strains. The highest zone of inhibition was measured as 21.2 mm for Cu NPs toward Escherichia coli and 16.7 mm for Cu/CuO blend toward Bacillus cereus bacteria. The highest zone of inhibition was measured as 13 mm and 13.8 mm for Cu/CuO blend toward Fusarium proliferatum and Penicillium verrucosum fungi. Cu/CuO blend showed notable photocatalytic activity towards Rhodamine B dye under visible light irradiation with 96% degradation rate within 120 min. Using the process developed in this study, copper and its oxide as nanoparticles can be produced from WPCBs and used for multifunctional applications. Graphical abstract
