Edge‐Engineered Interfacial Carrier Dynamics for Efficient Photocatalytic Gold Recovery
catalyst was successfully integrated onto a polyurethane foam (PUF) matrix and rigorously tested in a custom, pilot-scale continuous-flow photoreactor. This system achieved a 99% gold recovery rate from diverse e-waste and ore leachates. A detailed techno-economic analysis confirms the commercial viability of this approach, projecting a 2431.2% return on investment, thereby establishing a scalable photometallurgy paradigm for solar-driven, highly selective, and sustainable precious metals recovery.
