The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

Thin Reinforced Sulfonated Poly(phenylene sulfone) Membranes for Durable Water Electrolysis: Suppressed Swelling and Enhanced Stability Over 2000 Hours

open access: yesAdvanced Energy Materials, EarlyView.
Hydrocarbon membranes have the potential to significantly enhance the efficiency of water electrolyzers. However, their application is often limited by insufficient stability resulting from excessive swelling. This work presents a strategy to achieve efficient, safe and stable operation of a 24 µm thin hydrocarbon membrane by combining a modified ...
