A novel method called contact-electro-catalysis (CEC) has been developed to reduce precious metal ions in aqueous solutions. This method utilizes water-solid contact-electrification (CE) to drive redox reactions, enabling the efficient reduction of ions such as Ag⁺, Hg²⁺, Pd²⁺, Pt⁴⁺, AuCl₄⁻, and Ir³⁺ under both aerobic and anaerobic conditions. The study demonstrates that fluorinated ethylene propylene (FEP) microparticles, due to their high CEC activity, can effectively reduce these ions, achieving extraction capacities ranging from 0.756 to 722.5 mg g⁻¹ in 3 hours. The method is selective, recyclable, and capable of extracting gold from synthetic solutions with concentrations as low as 0.196 ppm. The research also shows that CEC can be used to extract gold from e-waste leachates, including those from central processing units (CPUs) and electroplating waste. The process is highly selective, with gold extraction efficiency reaching 94.4% after 20 hours, while other ions show minimal reduction. The method is simple, cost-effective, and environmentally friendly, with FEP demonstrating excellent recyclability and stability. The study highlights the importance of understanding the relationship between contact-electrification (CE) and CEC, particularly in terms of electron transfer and the influence of oxygen on reaction kinetics. Oxygen was found to hinder the reduction process in aerobic conditions, while anaerobic conditions enhanced the efficiency. The results suggest that CEC could be a promising alternative to traditional methods for recovering precious metals from e-waste, offering a sustainable and efficient solution for metal recovery. The method's potential for large-scale application is promising, provided the challenges of ultrasonic processes are addressed.A novel method called contact-electro-catalysis (CEC) has been developed to reduce precious metal ions in aqueous solutions.
