Dual Single Atoms Boosting Photocatalytic Upcycling of Raw Polyvinylidene Fluoride Plastic

open access: yesAdvanced Materials, EarlyView.
To resolve the catastrophic disaster of plastic contamination, the Cu‐Fe dual‐single‐atom‐loaded In2P3S9 NSs photocatalyst was prepared for direct conversion of raw polyvinylidene fluoride plastic into valuable chemicals. The dual‐single‐atom catalyst exhibits exceptional performance, with a total acetic/formic acid production of ∼1351.8 µmol g−1 ...

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

open access: yesAdvanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.
