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 ...

Single Atom Extracting Photoexcited Holes for Key Photocatalytic Reactions

open access: yesAdvanced Energy Materials, EarlyView.
The sluggish hole migration kinetic seriously suppresses the charge separation/transport in photocatalysis. Thus, this review summarizes the latest achievement of hole extraction in single‐/dual‐single atom photocatalysts for key energy/environment‐related reactions (e.g., water splitting, carbon dioxide reduction, nitrogen fixation, and wastewater ...
