Photo-thermo catalytic hydrogen production represents one of the most promising routes for channeling solar energy but typically suffers from high reaction temperatures. In this work, we develop photo-thermo catalytic hydrogen production at low temperatures by cost-effective, nonplasmonic, and metal-free nitrogen-doped carbon materials (CNO1–x ). We demonstrate that due to the photothermal conversion of CNO1–x , carrier generation is improved and electron migration is enhanced to suppress the recombination of electron–hole pairs, both of which promote hydrogen production by photocatalysis, while generated hydrogen radicals facilitate the regeneration of active sites for hydrogen production by thermocatalysis. Such synergy greatly promotes photo-thermo catalytic hydrogen production at low temperatures. These results demonstrate the great promise of photo-thermo catalytic hydrogen production over carbon materials at low temperatures.

In article number 2108300, Hang Zhao, Xianglong Han, Qianming Chen, and co-workers introduce a high-strength and injectable supramolecular hydrogel, which was constructed by the selfassembly of a monomeric nucleoside molecular gelator (2-amino-2'-fluoro-2'-deoxyadenosine, 2-FA). Notably, it also exhibits excellent biocompatibility, fast biodegradation, antibacterial properties, and osteoclast inhibition, making it a potential candidate biomaterial for tooth-extraction wound healing and tissue engineering.
