A dual-porphyrin heterostructure is successfully constructed by coupling tetrakis (4-carboxyphenyl) zinc porphyrin (ZnTCPP) with (4-hydroxyphenyl) (THPP). The high photocatalytic H2 evolution rate of 41.4 mmol h-1 g-1 obtained for ZnTCPP/THPP under full spectrum, which ≈5.1 and ≈17.0 times higher than that pure ZnTCPP THPP, respectively. significantly enhanced activity mainly attributed to the giant interfacial electric field formed between dual porphyrins, greatly facilitates efficient...
Abstract A full‐spectrum (300–850 nm) responsive donor–acceptor (D–A) supramolecular photocatalyst tetraphenylporphinesulfonate/fullerene (TPPS/C 60 ) is successfully constructed. The theoretical spectral efficiency of TPPS/C as high 70%, offering the possibility full‐solar‐spectrum light harvesting. performs a highly efficient photocatalytic H 2 evolution rate 276.55 µmol h −1 (34.57 mmol g ), surpassing many reported organic photocatalysts. D–A structure effectively promotes electron...
Abstract The ultrathin 2D self‐assembled tetrakis (4‐carboxyphenyl) zinc porphyrin (SA‐ZnTCPP) is successfully fabricated for photocatalytic hydrogen production. H 2 evolution rate 3487.3 µmol g –1 h under wide‐spectrum (300–698 nm), which increased by ≈85 times compared with metal‐free (SA‐TCPP). significant promotion in activity of SA‐ZnTCPP comes from the deep conduction band (−1.01 V) contributed elevation orbital energy level after Zn 2+ coordination. In addition, strong built‐in...
Charge separation efficiency of photocatalysts is still the key scientific issue for solar-to-chemical energy conversion. In this work, an electron donor-acceptor (D-A) interface with high charge between TPPS (tetra(4-sulfonatophenyl)porphyrin) and PDI (perylene diimide) successfully constructed boosting photocatalytic H
The insufficient charge separation and sluggish exciton transport severely limit the utilization of polymeric photocatalysts. To resolve above issues, we incorporate bountiful carboxyl substituents within a novel benzodiimidazole oligomer assemble it into crystalline semiconductor. photocatalyst is polar, hydrophilic, short-range crystalline, capable both hydrogen oxygen evolution. introduction side-groups adds asymmetry to local structure increases built-in electric field. Further,...
Although the internal electric field (IEF) of bismuth oxyiodide (BiOI) is acknowledged as a potent driving force for efficient charge separation, enhancing intensity IEF remains challenge. Herein, highly crystalline BiOI nanosheets with I‐rich surface are employed to intensify and direct migration. In comparison I‐poor nanosheets, which possess Bi−O layer termination I‐defects, demonstrates 62.5‐fold improvement in its well‐developed high structure, direction reversed by layers. This...
Water oxidation is a critical reaction in artificial photosynthesis which limited by high energy barrier and often requires matching cocatalysts. Dual cocatalysts Co3O4 Pt are combined with perylene diimide (PDI) polymer, accomplishing photocatalytic O2 production rate of 24.4 mmol g–1 h–1 under visible light irradiation, 5.4-fold enhancement compared PDI alone. Moreover, the apparent quantum yield evolution reaches 6.9% at 420 nm remains 1.2% 590 nm. The dual cocatalysts-constructed...

Electrocatalytic overall water splitting of S-NiMoO 4 /NF under alkaline conditions.
Abstract The unfavorable water dissociation and continuous dissolution of Pt single‐atom catalysts significantly impede their practical application in alkaline anion exchange membrane electrolyzers (AEMWEs). Herein, by integrating the electron‐buffer functionality rare earth single atoms (RE = Pr, Ce, Gd, Sm) dispersed on N‐doped carbon substrates (N─C) with atoms, a novel catalyst Pt/RE‐N‐C is reported. constructed Pt─N─Ce bridge causes electron enrichment sites deficiency RE sites, which...
