Robust Mix‐Charged Polyzwitterionic Hydrogels for Ultra‐Efficient Atmospheric Water Harvesting and Evaporative Cooling

Advanced Materials, EarlyView.
Conventional atmospheric water‐harvesting hydrogels prioritize hygroscopicity at the expense of mechanics, hindering its practical applications. The proposed hygroscopic mix‐charged polyzwitterionic hydrogel(THMPH) achieves a trade‐off between high water absorption and exceptional mechanical robustness through a strength gradient‐enhanced ionic cross ...

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

Advanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.
