摘要：The effective recycling of metals, reduction of environmental pollution, and promotion of resource sustainability have emerged as critical research priorities. Photoelectrochemical (PEC) technology has demonstrated distinct advantages over conventional methods in both metal pollution remediation and resource recovery, yet substantial challenges remain for its practical implementation. This review systematically examines recent advancements in PEC metal ions (Li , Cu2 , Ni2 , Ag , et al.) recovery technology form lithium battery, seawater, and metallic wastewater. The integrated strategy of photoelectrode design, ion selective membrane optimization, and microbial synergy was systematically explored for the first time, and an interdisciplinary path from laboratory to industrial implementation of PEC technology was proposed. It is structured into three comprehensive sections. Initially, the fundamental working mechanisms and key influencing factors of PEC metal recovery was elucidated. Subsequently, a detailed analysis of PEC system design strategies is summarized, including photo-electrode architecture, electrolytic cell optimization, and ion-permeable membrane engineering, while identifying technical barriers in current PEC metal ions recovery processes. Conclusively, a forward-looking perspective on the future development of PEC technology was provided. The ongoing research and practical applications of this technology in metal ion recovery for resource recycling are expected to create new opportunities.
