Abstract Insufficient charge separation and slow exciton transport severely limit the utilization of perylene‐plane‐based organic photocatalysts. Herein, a novel PTCDA/PTA (perylene‐3,4,9,10‐tetracarboxylic dianhydride/perylenetetracarboxylic acid) is successfully prepared for first time by in situ crystallization PTA on surface PTCDA through π – interaction. The loading with 8%PTCDA showed optimum photocatalytic performance. H 2 evolution rate reached 45.06 mmol g −1 h , which 1.93‐fold 4506.00‐fold higher than that pure PTCDA. Meanwhile, it also exhibited excellent antibiotics photodegradation activities, both removal efficiency tetracycline hydrochloride (TC‐HCl) ofloxacin (OFL) are more over 90% within 30 min. By modulating structures perylene plane, steric hindrance internal dipole moments can be precisely tuned. These lead to change stacking mode, promoting degree formation strong electric field, while improved activity. Excited state density functional theory (DFT) calculations unveil redistribution electron‐hole pairs, obeys type II mechanism. proposed mechanism determined liquid chromatography‐mass spectrometry (LC‐MS). Besides, toxicities degradation products evaluated. work provides useful strategy design high‐performance multifunctional photocatalysts toward water remediation energy production.

Photocatalytic CO2 conversion for hydrocarbon fuel production has been known as one of the most promising strategies achieving carbon neutrality. Yet, its efficiency remains unsatisfactory mainly due to severe charge-transfer resistance and slow charge kinetics. Herein, a tunable interfacial transfer on an oxygen-vacancies-modified bismuth molybdate nanoflower assembled by 2D nanosheets (BMOVs) bismuthene composite (Bi/BMOVs) is demonstrated photocatalytic conversion. Specifically, meticulous design Ohmic contact formed between BMOVs can allow modulation resistance. According density functional theory (DFT) simulations, it ascertained that such exceptional kinetics attributed built-in electric field (IEF) contact. As such, reduction performance optimized Bi/BMOVs (CO CH4 productions rate 169.93 4.65 µmol g-1 h-1 , respectively) ca. 10 times higher than pristine BMO rates 16.06 0.51 respectively). The reported in this work shed some important light highly efficient photocatalysts both energy environmental applications.
