ABSTRACT / САЖЕТАК:
This paper explores the feasibility and efficacy of employing whole CPU (Central Processing Unit) recycling as a sustainable source of metals for catalyst coatings in the Hydrogen Evolution Reaction (HER). With the escalating global issue of electronic waste (e-waste), repurposing discarded CPUs offers a promising avenue for metal recovery and utilization. Through systematic experimentation, CPU preparation technique was evaluated for formation of electrode catalytic layer and the kinetics of HER in alkaline media. The resulting electrodeposited cathode was assessed for electrocatalytic efficiency. Our findings highlight the potential of utilizing e-waste-derived metals, particularly gold and copper, as effective catalyst coatings for HER, thus contributing to sustainable metal recovery and utilization strategies.
