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 ...

Impact of Cathode Microstructure on Sulfur Redox Kinetics in Lithium–Sulfur Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The morphology and particle size of a ketjenblack/sulfur composite (SD‐KB/S) are controlled to optimize the cathode microstructure. After deconvoluting the cell overpotential, the activation overpotential is revealed to be notably reduced for an SD‐KB/S electrode; the concentration overpotential emerges as a prominent barrier at the potential‐limiting ...
