Covalent organic frameworks promoted single metal atom catalysis: Strategies and applications

Enhanced photocatalytic activity of TiO2/UiO-67 under visible-light for aflatoxin B1 degradation

“…Metal organic frameworks (MOFs) have attracted extension because of their large specific surface area, large pore volume, and the ability to introduce different electron densities by adjusting the length of the ligand. 22–24 In addition, the electrons of some MOFs can be transferred from HOMO to LOMO, and further generate photo-generated electrons and holes under the excitation of light, which can be used as photocatalysts. 25–27 Based on these advantages, MOFs with appropriate band gaps can be used to construct various types of heterojunctions with TiO 2 to enhance photocatalytic performance.…”

Single-atom catalysts for high-efficiency photocatalytic and photoelectrochemical water splitting: distinctive roles, unique fabrication methods and specific design strategies

“…Although the reports about COF-based SACs for photocatalytic water splitting are limited, COFs exhibited great potential to function as substrates for SAC fabrication. [237][238][239] For instance, Dong et al have anchored Pt SAs on the pore walls of 2D b-ketoenaminelinked COFs (Pt1@TpPa-1), which exhibited a superior photocatalytic performance than Pt NPs/TpPa-1 under visible light irradiation. 237 As shown in Fig.…”

Donor–Acceptor Hybrid Heterostructures: An Emerging Class of Photoactive Materials with Inorganic and Organic Semiconductive Components

“…Thus, it is perfectly tenable that photochromic materials have extensive application prospects in the field of decoration, molecular machines, and anti‐counterfeiting. [ 79 ]…”

“…Thus, it is perfectly tenable that photochromic materials have extensive application prospects in the field of decoration, molecular machines, and anti-counterfeiting. [79] The common photochromic materials are organic dyes, such as azobenzene, spiropyran, fulgide, and diarylethylene. [78] Although these organic dye molecules have certain advantages in discoloration, their practical applications are severely limited due to poor stability, weak fatigue resistance, and thermal instability.…”
