Enhancing the performance of pollution degradation through secondary self-assembled composite supramolecular heterojunction photocatalyst BiOCl/PDI under visible light irradiation

Heterostructured Perylene Diimide (PDI) Supramolecular Nanorods with SnO2 Quantum Dots for Enhanced Visible‐Light Photocatalytic Activity and Stability

“…[9] Therefore, introducing a potential gradient in the PDI supramolecular catalyst is a useful strategy to promote the excitons dissociation and carrier migration and ultimately realize improved separation efficiency of carriers. General methods mainly include constructing metal/carbon material-semiconductor composite (such as Pt QDs/PDI, [10] PDI@Au NPs, [11] PTCDI-C 60 , [12] PDI/rGO [13] ), coupling of semiconductor-semiconductor (such as p-Ag 2 S/n-PDI, [14] PDI/BiOCl, [15,16] Bi 2 WO 6 /PDI [17] ) or introducting of external electric field, [18] etc. Herein, hetero-structured PDI supramolecular photocatalyst with another matched semiconductor photocatalyst to construct a novel and powerful photocatalytic composite is reasonable.…”

Copper-doped perylene diimide supramolecules combined with TiO2 for efficient photoactivity

“…A small shi of this peak is detected in CuPDIsm (400.4 eV) and TiO 2 /CuPDIsm (399.8 eV), indicating that the chemical environment of N 1s changed aer PDIsm was dopped with Cu and coupled with TiO 2 . 48 The Cu 2p spectrum (Fig. 3f) exhibits that two major peaks at 934.6 and 954.6 eV are ascribed to Cu 2p 3/2 and Cu 2p 1/2 valence states, respectively, conrming the presence of Cu as Cu 2+ oxidation state 49 in CuPDIsm.…”

Synthesis, Functional Modifications, and Diversified Applications of Hybrid BiOCl-Based Heterogeneous Photocatalysts: A Review

“…241 The composites can be easily driven by a full spectrum to realize the rapid transfer of interfacial electrons from PDI to BiOCl due to the interaction of the heterogeneous interface and conjugated structure of PDI, thereby realizing the efficient degradation of phenol. In order to optimizing photocatalytic activity of PDI/BiOCl composites under visible light irradiation, sheet-like PDI/ BiOCl photocatalysts were developed by a facile water bath heating process, 227 which can tailor the energy band structure of composites, leading to the different exposed surfaces and narrow charge carrier transfer route as well as a stronger visible light response. This composite achieved the fast degradation of RhB, MO, and phenol under visible light irradiation.…”

“…Organic species − (such as g-C 3 N 4 , PANi, PDA, PAN, PPy) have been extensively investigated as superior supports for converting solar energy into chemical energy because of their excellent thermal and chemical tenability, the controllable microstructure, and strong visible light response. Therefore, the photocatalytic performances of organic species/BiOCl composites were higher than that of the pristine BiOCl. − Currently, the organic species/BiOCl photocatalysts have been majorly employed for pollutant removal, and their synthetic methods, reactants, and applications are summarized in Table . In this section, research progress made in organic species/BiOCl nanostructures will be clarified.…”

“…Other organic species (including PANi, PPy, PDA, and PAN)/BiOCl composites can also display higher photocatalytic activity than those of the individual BiOCl and organic photocatalysts. , For example, Gao and co-workers have successfully achieved the modification of PDI sheets on the surface of rod-like BiOCl by using a co-deposition method . The composites can be easily driven by a full spectrum to realize the rapid transfer of interfacial electrons from PDI to BiOCl due to the interaction of the heterogeneous interface and conjugated structure of PDI, thereby realizing the efficient degradation of phenol.…”
