Protophilic TiOx/Ti3C2Tz Nanosheets for Hyper‐Efficient Closed‐Loop Pd Recycling

open access: yesAdvanced Functional Materials, EarlyView.
Protophilic TiOx/Ti3C2Tz NSs enable selective Pd(II) recovery through in situ adsorption‐reduction into Pd(0) NPs from spent catalyst leachates and industrial wastewaters. The resulting Pd/NS composites are directly upcycled as efficient HER electrocatalysts or regenerated for reuse through controlled surface regeneration.
