Enhancement of visible-light-driven photocatalytic H 2 evolution from water over g-C 3 N 4 through combination with perylene diimide aggregates

Supramolecular organic nanofibers with highly efficient and stable visible light photooxidation performance

“…15 The high thermal and photostability of PDI makes it an ideal candidate for water oxidation photocatalyst. Recently, the supramolecular architectures of PDI were employed as antennae chromophores working with the photocatalysts to construct water splitting system, [16][17][18][19] such as PDI-Ni, [16] PDI-Ru, [17] PDI-TiO2 [18] and PDI-C3N4 [19].…”

pH dependent photocatalytic hydrogen evolution by self-assembled perylene bisimides

“…2,[4][5][6][7] Interestingly, some PBIs are used as LMWGs as they can selfassemble into a wide range of structures as a result of noncovalent interactions including hydrogen bonding, van der Waals interactions and p-p stacking. 8,9 PBIs have also been successfully used as photocatalysts for a range of reactions including hydrogen evolution, [10][11][12][13][14][15][16] water oxidation 17 and the reduction of aryl halides. 18,19 Proton reduction, or the Hydrogen Evolution Reaction (HER), is a widely studied half reaction from the water-splitting process.…”

TiO2@Perylene Diimide Full‐Spectrum Photocatalysts via Semi‐Core–Shell Structure

“…Perylene diimide (PDI) self‐assembly has attracted much attention in solar cells, sensors, fluorescence probes, n‐transistors, and photocatalysts . In photocatalysis, PDI self‐assembly and its composites can be used for photocatalytic hydrogen production, oxygen production, dye degradation, dehalogenation, and CC coupling reaction, attributed to excellent visible‐light absorption, charge conductivity, structural modifiability, morphology controllability, and performance optimization. However, PDI self‐assembly has not been industrialized on a large scale, since there are two main problems: high electron–hole recombination leads to low utilization of the solar energy; and it can only absorb visible light while near‐infrared light and ultraviolet light cannot be effectively utilized.…”

“…To this end, many complexes based on PDI self‐assembly have been prepared, such as C 3 N 4 –PDI, TiO 2 –PDI, and Zn x Cd y S–PDI . Due to interfacial charge transfer, these complexes can greatly boost visible‐light photocatalytic activity due to interfacial charge transfer, but they cannot enhance ultraviolet‐light photocatalytic activity and the research on these aspects was not in‐depth as well.…”
