A novel photocatalytic platform based on the newly-constructed ternary composites with a double p-n heterojunction for contaminants degradation and bacteria inactivation

New potential of boron-based COFs: the biocompatible COF-1 for reactive oxygen generation and antimicrobial applications

“…The band gap of the material was calculated by using the Kubelka–Munk equation. 19 According to the existing literature, COF-1 is a direct semiconductor, 41 so the Y -axis of the graph is ( F ( R ) × E ) 0.5 . The measured band gap was 3.78 eV, which was in good agreement with the existing literature (∼3.5 eV), 41 indicating that COF-1 can reasonably use the excitation of visible light to transfer electrons from the ground state to the excited state.…”

“…42 Because of the positive slope of the Mott–Schottky curve (Fig. 3d), 19 it can be determined that COF-1 is an n-type semiconductor with the value of the flat band (FB) potential being −1.13 eV. The conduction band (CB) potential of the n-type semiconductor is about 0.1–0.3 eV more negative than its FB potential, from which the CB and valence band (VB) potentials of COF-1 can be calculated to be −1.33 eV and 2.45 eV, respectively.…”

“…Nowadays, there have been some reports on the antibacterial applications of COFs and there is room for more. Among the published studies of COFs for antibacterial attempts, different bactericidal mechanisms have been used, mainly including photocatalytic sterilization, 13,19–21 cationic sterilization 22 and biomolecular composites. 23 From the above studies, it can be summarized that photocatalytic sterilization plays the main role.…”

Heterostructured hybrids of metal–organic frameworks (MOFs) and covalent–organic frameworks (COFs)

“…Furthermore, these hybrids were introduced into a certain amount of PANI solution, assembling MIL-88B@COF@PANI composites with significant photocatalytic activity. 92…”

Rational Design and Application of Covalent Organic Frameworks for Solar Fuel Production

“…A new COF material decorated with Pt was reported to be photoactive in the decarboxylative difluoroalkylation and oxidative cyclization reaction [ 42 ]. Several other reports explored the photocatalytic degradation of organic pollutants, dyes, chlorinated biphenyls [ 43 , 44 ]. A mechanochemical approach of ball milling synthesis method for TpMA (1,3,5-triformylphloroglucinol melamine)-COF material was explored in the photocatalytic degradation of phenol [ 45 ].…”
