Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

open access: yesAdvanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...
