“…The creation of copper nanoparticles has been described in numerous scientific works using chemical, physical, and biological methods [33]. The biological method uses natural reducing agents that can be found in plant extracts, fungi, and bacteria to convert copper salt into copper nanoparticles [34][35][36]. A commendable job has been done regarding the production and stability of copper nanoparticles by using biological processes.…”

In the last decades, antibiotics were used to treat infections caused by some Staphylococcus species, especially Staphylococcus aureus and Staphylococcus epidermidis. The widespread use of antibiotics to treat staphylococcal infections has resulted in an increase in the resistance of bacteria to antibiotics, particularly to beta-lactam antibiotics. In recent years, researchers have been working on developing new antibiotics, despite the fact that they are complex and expensive and carry a number of risks associated with drug toxicity. Using new substances that have good potential against bacterial infection without causing bacteria to become resistant to these substances is currently being researched. More research has been carried out on the effect of silver and copper nanoparticles in neutralizing staphylococcal infection in laboratory studies. The toxic effect of nanoparticles was a concern to scientists, but despite that, the studies in vivo found that there was no toxic effect at low doses of nanoparticles on rats. The findings in this field were acceptable to entice researchers to develop these substances.

“…However, until our days no many efforts appeared in this direction. Wong-Pinto et al utilized a real effluent produced by the leaching of sulfide ore tailings as a copper source to synthesize copper nanoparticles (CuNPs) using the non-pathogenic bacteria P seudomonasstutzeri DSM 5190 as a bio-reducing agent [21]. In order to extract the Cu from the chalcopyrite-bearing tailings, they were treated with H 2 SO 4 solution (120 g L −1 ) in presence of sodium nitrate (1 g L −1 ) that acted as an oxidizing reagent able to enhance Cu dissolution.…”

Mining waste can generate environment pollution including acid mine drainage (AMD). AMD is dangerous for its surroundings and can pollute surface and groundwater it is contacting with. Nanomaterials are advanced materials used in all fields of human activity and development. However, their production is still expensive and may pollute the environment due to the chemicals’ used and/or production of the energy needed for their synthesis. A smart solution could be use of mining waste and AMD to produce nanomaterials with properties similar to the properties of nanomaterials obtained from clean chemicals. Thus both waste will be valorised / decontaminated and useful and needed materials produced. This paper presents production of nanoparticles and nanomaterials from mining waste and AMD with emphasis on iron- and copper-based materials, as well as some applications of the obtained materials.

“…with copper salt; this process comprises the reduction of copper ions in the presence of active ingredients, contributes to the formation of Cu 0 and then, through agglomeration, forms oligomeric clusters, thus leading to colloidal CuNPs. It is considered a reaction between metabolites and chemical groups found in the cell wall of dead biomass or extracellular metabolites, in addition to being a spontaneous reaction, [6] Figure 1. Some authors have reported the synthesis of CuNPs using various plant extracts using every part as the stem, flower, fruit, and root [7–9] .…”

This study presents a green method of producing copper nanoparticles (CuNPs) using aqueous extracts from Sargassum spp. as reducing, stabilizing, and capping agents. The CuNPs created using this algae‐based method are not hazardous, they are eco‐friendly, and less toxic than their chemically synthesized counterparts. The XRD characterization of the CuNPs revealed the presence of Cu and CuO, with a crystallite size ranging from 13 to 17 nm. Following this, the CuNPs were supported onto a carbon substrate, also derived from Sargassum spp. (biochar CSKPH). The CuNPs in biochar (CuNPs‐CSKPH) did not appear in the XRD diffractograms, but the SEM‐EDS results showed that they accounted for 36 % of the copper weight. The voltamperometric study of CuNps‐CSKPH in acid media validated the presence of Cu and the amount was determined to be 2.58 μg. The catalytic activity of CuNPs‐CSKPH was analyzed for the electrochemical reduction of CO2. The use of Sargassum spp. has great potential to tackle two environmental problems simultaneously, by using it as raw material for the synthesis of activated biochar as support, as well as the synthesis of CuNPs, and secondly, by using it as a sustainable material for the electrochemical conversion of CO2.
