The donor-acceptor (D-A) interactions between the triazine ring unit and adjacent substituents is one of the decisive factors that affect the performance of triazine-based conjugated polymer photocatalysts. Herein, we design and synthesize novel conjugated polymers by introducing electron-drawing 1,3,4-oxadiazole units into 1,3,5-triazine-based π-conjugated skeletons for photocatalytic hydrogen production. Compared with the bulk polymer, the modified photocatalysts show extended visible light harvesting and boosted charge separation. Notably, under the irradiation of full-spectrum solar light, as-synthesized polymer with bi-1,3,4-oxadiazole linkage (denoted as TCP-BOXD) shows a highly improved hydrogen-evolving rate up to 3000 μmol g −1 h −1 . Furthermore, DFT calculation reveals that N atoms in the introduced 1,3,4-oxadiazole unit, coupled with those in the triazine ring, act as synergistic bi-active sites for superior photocatalytic hydrogen production. Our findings may help the rational design and controllable synthesis of novel triazine-based conjugated polymers for photocatalysis. • Novel triazine-based conjugated polymer photocatalysts were synthesized. • π-conjugated polymers show extended visible light harvesting and boosted charge separation. • The modified polymer shows a highly improved hydrogen-evolving rate up to 3000 μmol g −1 h −1 . • DFT calculations reveal that N atoms in the introduced unit act as a synergistic active site. 

Regulating Donor-Acceptor Interactions in Triazine-Based Conjugated Polymers for Boosted Photocatalytic Hydrogen Production

Environmental pollution and resource shortage are two major challenges facing the world today, and resourcization of precious metals is one of the effective strategies to confront these problems. Precious metals, known for their high performance and scarcity, are indispensable our current lives. As nonrenewable resources, the demand and consumption of precious metals are increasing every year. Therefore, it is necessary to develop green and efficient precious metal recovery technologies to alleviate the environmental and resource crisis. This perspective summarizes various typical precious metal recovery strategies and pays attention to innovations from traditional technologies. We also evaluate and prospect the above methods based on secondary pollution and recovery efficiency.
