Recent developments of electrodeposition-redox replacement in metal recovery and functional materials: A review

One way to overcome the complex problem of increasing demand for metals coupled with rapid depletion high-grade raw materials is boost research into innovative methods metal recovery. Electrochemical recovery production has already gained ground in electrowinning and electrorefining Cu, Zn, Au, example, from highly concentrated purified hydrometallurgical solutions. Since 2015, an electrochemical technique, based on combination electrodeposition (ED) redox replacement (RR) processes, been developed context trace (μg/L – mg/L). Specifically, EDRR enables efficient precious metals, including Ag, Pt, Te, underutilized secondary materials-hydrometallurgical solutions, where these species are naturally present. With flexible process parameters, also allows controllable preparation coatings, nanoparticles, even functional surfaces directly lower-grade resources, further indicating promise relieve material scarcity. In this review, we analyze detail significant progress regarding both behavior creation high-value-added materials. The future prospects EDRR, energy efficiency sustainable materials, outlined.
