Metallic active-site engineering: a bridge between covalent triazine frameworks and high-performance catalysts

Abstract

Covalent triazine frameworks (CTFs) with structure designability and multifunctionalities have aroused increasing attention in conventional thermocatalysis and modern photocatalysis/electrocatalysis. However, many obstacles still exist on the road to simultaneously achieving...

The Rapid Mechanochemical Synthesis of Microporous Covalent Triazine Networks: Elucidating the Role of Chlorinated Linkers by a Solvent‐Free Approach

“…[16,17] Additionally, the introduction of these nitrogen functionalities enables the coordination of metal particles for application in catalysis, or can be used to enhance gas uptake capacities in gas storage devices due to an electrostatic interaction between the nitrogen-containing moiety and the gas molecules. [18][19][20][21][22][23][24][25][26][27][28][29] Initially, the generation of porous triazine-containing polymers was achieved by ionothermal trimerization of aromatic nitriles in molten ZnCl 2 , requiring harsh reaction conditions of 400-600 °C. [25,[30][31][32] To circumvent the high melting point of ZnCl 2 , and thereby an accompanied undesired carbonization of the polymer, the reaction can be carried out either in an eutectic salt mixture or in a microwave, still requiring a reaction temperature of 200 °C or exhibiting a challenging reaction control, respectively.…”

Strategies to improve the photocatalytic performance of covalent triazine frameworks

“…These unique properties enable CTFs to form strong nitrogen-metal interactions, which allows for the integration of other materials to establish composite structures with enhanced performance. 210 Transition metal phosphides (TMPs) have gained signicant attention in the eld of photocatalysis due to their exceptional electrical conductivity, cost-effectiveness, and versatile composition. For instance, Ni 2 P alloys have shown excellent performance in photocatalytic H 2 evolution from water, making them a potential alternative to Pt as a cocatalyst.…”

Functional COFs for Electrochemical Sensing: From Design Principles to Analytical Applications

“…Covalent organic frameworks (denoted as COFs) are an emerging class of crystalline porous organic polymer materials formed by organic building blocks only containing light elements (C, H, N, O, B and Si) via strong covalent bonds including CÀ C, CÀ N, C=N, C=CÀ N, CÀ O, BÀ O and so on [1][2][3][4] using the principle of reticular chemistry. Since the first report in 2005 by Yaghi's group, [5] COFs, as a kind of star porous materials, have demonstrated great application potential in various fields [6][7][8][9][10][11] such as gas adsorption and storage, [12][13][14][15][16][17][18] heterogeneous catalysis, [19][20][21][22][23][24][25][26] optoelectronics, [27][28][29] energy conversion and storage, [30][31][32][33][34][35][36][37][38][39][40] proton conductivity, [41,42] drug delivery, [43][44][45]…”
