Ce‐Doped Lignin‐Based Nanozyme with Heat‐Activated Hydrolase Activity

open access: yesAdvanced Science, EarlyView.
A novel Ce‐doped lignin‐based hydrolase nanozyme (Ce‐AL) is synthesized using Ce ions coordinated with aminated industrial lignin. The Ce‐AL effectively hydrolyzes phosphate ester bonds and protein amide bonds, maintain high activity at 100°C, and successfully fights bacteria biofilms.

How Halide Segregation Governs the Ion Density Evolution and Ionic Performance Losses: From Degradation to Recovery

open access: yesAdvanced Energy Materials, EarlyView.
Halide segregation (HS) in mixed‐halide wide‐bandgap (WBG) perovskites is key to the stability of perovskite‐based tandem cells and a central focus of large‐scale research efforts. Here, we find that the underlying reason for the poor stability of cells prone to HS is enhanced ionic losses during operation. Furthermore, we identified irreversible ionic

Restricting Copper Reconstruction with Ultrathin Polydopamine for Selective and Stable Electrochemical CO2 Reduction Reaction to C2 Products

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
An ultrathin polydopamine coating on copper microcubes mitigates the surface reconstruction during EC‐CO2RR. Copper nanocubes form on the surface of the microcubes in the early stages of the EC‐CO2RR, contributing to suppressed surface reconstruction and sustained Faradaic efficiency for C2 products.
