Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse
Advanced Science, EarlyView.An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Advanced Energy Materials, EarlyView.While perovskite solar cells have been widely studied, including their stability, perovskite indoor photovoltaics (IPVs) have only recently emerged. Nevertheless, more studies are appearing in the literature. The systematic stability study of IPVs is crucial, particularly given the inconsistencies in reported methodologies and results, which call for ...
