Efficient integration of covalent triazine frameworks (CTFs) for augmented photocatalytic efficacy: A review of synthesis, strategies, and applications

“…To enhance the absorption of visible light by derivatives of CTFs, along with the separation of e − /h + pairs and the overall η c , a spectrum of strategies has been devised to augment photocatalytic activity. These encompass the regulation of morphology and structure to expand specific surface area [ 39 , 81 , [104] , [105] , [106] , [107] , [108] ], the construction of defects [ 44 , 50 , [109] , [110] , [111] , [112] , [113] , [114] ], and the introduction of heteroatom doping [ [63] , [64] , [115] , [116] , [117] , [118] , [119] , [120] , [121] , [122] , [123] , [124] , [125] , [126] , [127] , [128] , [129] , [130] , [131] , [132] , [133] ] to tailor energy level configurations. Additionally, the fabrication of nanostructures and interfacial heterostructures has been employed to expedite carrier separation, among other approaches.…”

“…Semiconductor behavior within CTFs can be finely tuned through the introduction of heteroatoms, including but not limited to N, O, S, B, P, Fe, Pt, and others. This versatile doping strategy offers an effective and alternative means of modulating surface charge characteristics, altering energy level structures, enhancing light absorption capacities, and expediting charge transfer rates, all of which collectively serve as potent strategies to amplify the catalytic efficacy of heterogeneous CTF systems [ 63 , 64 , [123] , [124] , [125] , [126] , [127] , [128] , [129] , [130] , [131] , [132] , [133] ]. To date, extensive research has been conducted on the doping of nitrogen, phosphorus, sulfur, and boron [ 64 , 110 , [175] , [176] , [177] , [178] ].…”

“…As an environmentally sustainable photocatalyst that efficiently harnesses solar energy, CTFs exhibit significant promise for a wide range of applications in photocatalytic resource recycling and carbon reduction. They mainly introduce the applications in photocatalytic water splitting for H 2 [ 107 , 126 , 145 , 150 , 156 , 171 , 178 ] and H 2 O 2 [ 52 , 53 ] evolution, reduction of CO 2 into hydrocarbon fuels [ 180 , [211] , [212] , [213] ], and degradation of pollutants [ 133 , 214 , 180 , 215 ], as well as the involved photocatalytic nitrogen fixation [ 121 ,122, 216 ] accordingly. Several papers have been evaluated and summarized based on the most recent findings to provide a quick knowledge of CTF composites for various photochemistry applications.…”

A critical review on emerging photoactive porous materials for sulfide oxidation and sulfur mustard decontamination

“…130 CTFs are considered promising porous, layered, conjugated material with aromatic CvN linkages (triazine unit), endowing them with unique characteristic features like high chemical stability and rich nitrogen content. 131 CTFs found numerous appli-cations in separation, photocatalysis like CO 2 reduction, 132 pollutant degradation 133 and heterogeneous catalysis. 134,135 Wang and co-workers reported crystalline 2D-CTFs synthesized via controlling dual modulators for the effective photochemical oxidation of sulfides to less toxic sulfoxides.…”

Thiophene-Based Covalent Triazine Frameworks as Visible-Light-Driven Heterogeneous Photocatalysts for the Oxidative Coupling of Amines

“…CTFs [13][14][15][16] are a subclass of COFs formed by structural triazine rings connected through covalent bonds into an extended porous framework with promising characteristics, including semi-crystallinity, high surface areas, physicochemical and thermal stability and a high nitrogen content. Thanks to these specific properties, CTFs have great potential in a wide range of applications, such as gas separation, energy and gas storage [17,18], as well as photo/electro/thermo-catalysis [19][20][21].…”
