Strategies to improve the photocatalytic performance of covalent triazine frameworks

Abstract

Covalent triazine frameworks (CTFs) have emerged as a prominent group of organic semiconductors, distinguishing themselves from covalent organic frameworks (COFs) for their applications in photocatalysis. Their unique features, such as...

Covalent triazine-based frameworks – switching selectivity in HMF photooxidation

“…16,17,36,37 While most photocatalytic studies focus on boosting water splitting, [38][39][40] hydrogen production [41][42][43][44] or carbon dioxide reduction, [45][46][47] only a few reports consider the potential of tailor-made CTF photocatalysts for metal-free organosynthesis. [48][49][50][51][52][53][54][55] Especially, CTF's ability to activate molecular oxygen makes it promising for benign oxidations. 35 Zhang et al demonstrated the successful oxidation of several benzyl alcohols to the corresponding aldehydes or ketones with a thiophene based CTF.…”

Enhancement of covalent triazine frameworks containing S heteroatom for photocatalytic hydrogen evolution: the role of composite PEG

“…As expected, it can increase the adsorption of visible light, reduce the recombination of free charges, enhance the transport mobility of carriers, and ultimately improve the photocatalytic performance. 10–17…”

Efficient Photocatalytic System based on Schiff‐Base Type Hybrid Polymers for Energy Conversion and Water Treatment

“…2,4,6-Tris(4-formylphenyl)-1,3,5-triazine (TFPT), as another functional monomer, a stable conjugate system exists between C and N rings in its structure. [14] By adjusting the stoichiometric ratio of aldehydes and amines, the π-conjugated system of the obtained material can be optimized, which can change the molecular structure and regulate the energy band structure, thereby improving the photocatalytic activity. Two precursors, TFPT and OAPS, were bonded through C=N to obtain a three-dimensional network structure with an extended π-electron conjugated system, achieving synchronous control of the electronic and topological structure of the catalyst.…”
