After reaction, the spent perovskite\u2010loaded sponge can be readily collected, and an efficient closed\u2010cycle recovery strategy combining resin\u2010adsorption, gradient\u2010elution, directional\u2010deposition, and targeted\u2010conversion is employed to reclaim lead as PbBr\n                    <jats:sub>2<\/jats:sub>\n                    , achieving a recovery efficiency of 95.01%. Crucially, the CsBr\u2010rich DMSO solution and the purified DMSO solvent are simultaneously recovered and directly reused for perovskite resynthesis, significantly reducing reagent consumption and environmental impact. The regenerated photocatalyst maintains stable performance over five consecutive catalysis\u2010recovery\u2010regeneration cycles, retaining over 80% of initial production rates for CO and CH\n                    <jats:sub>4<\/jats:sub>\n                    , which demonstrates excellent sustainability and operational stability. Importantly, this strategy demonstrates broad applicability for recycling lead from diverse perovskite compositions.
