Thiophene-incorporated CTFs with boosted intramolecular charge transfer and defect-abundant networks for potent photosensitized oxidation of organics

A thiazolo[5,4-d]thiazole functionalized covalent triazine framework showing superior photocatalytic activity for hydrogen production and dye degradation

“…This is consistent with the trend observed from the UV-Vis DRS spectra. 76,77 Furthermore, in the HOMO and LUMO of CTF-NWU-1, the delocalized electrons pass through almost the entire structure (Fig. 4c), while in CTF-NWU-2 the delocalized electrons are concentrated around the triazine ring (Fig.…”

Regulating the Content of Donor Unit in Donor–Acceptor Covalent Triazine Frameworks for Promoting Photocatalytic H2 Production

“…[15][16][17][18][19] And with triazine moieties as inherent acceptors, the construction of donor-acceptor configuration in CTFs has been regarded as one of the most convenient and effective methods to achieve this goal. [20][21][22][23][24][25] However, most of the published studies have focused on qualitatively investigating the effects of various donor groups on the catalytic properties of CTFs, while few reports have quantitatively investigated the effects of donor unit content (Dcontent) on the optical properties and photocatalytic activities of CTFs.…”

“…To improve the photocatalytic activities, a series of targeted strategies have been put forward, such as the introduction of heteroatoms, the extension of π‐conjugated configurations, improvement of crystallinity, and adjustment of pore size [15–19] . And with triazine moieties as inherent acceptors, the construction of donor–acceptor configuration in CTFs has been regarded as one of the most convenient and effective methods to achieve this goal [20–25] . However, most of the published studies have focused on qualitatively investigating the effects of various donor groups on the catalytic properties of CTFs, while few reports have quantitatively investigated the effects of donor unit content (D‐content) on the optical properties and photocatalytic activities of CTFs.…”

Alkaline Earth Metal Intercalated into Carbon Nitride Nanosheets for Photocatalytic Peroxymonosulfate Removal of Refractory Organic Pollutants

“…Zhang et al 44 and Chen et al 45 found that the π−π interaction between BPA and the catalyst promoted the adsorption and electron transfer process of BPA in the photodegradation reaction, thus improving the degradation activity of BPA. Importantly, Li et al 46 found that the edge defects of the material can act as highenergy adsorption sites for enriched organic matter, which brings the generated reactive oxygen species (ROS)s closer to the pollutants (represented by BPA) and has a greater chance of attacking these molecules. Therefore, in this study, the modified CN, including BaCN, SrCN, and CaCN, has abundant edge defects (cyano group), which further promotes the adsorption and activation of BPA, thus improving the photocatalytic activity.…”
