Published: July 19, 2024

This work describes the synthesis of C@BiOBr using glucose as carbon precursor by a repeatable one-step hydrothermal method. Characterization studies indicate that structure BiOBr did not change after layer was encapsulated on surface. The highest activity is achieved at 1.2-C@BiOBr, with 97% phenol (50 mg·L-1) degrading within 90 min, and degradation amount determined to be 48.5 mg·g–1 speed 0.54 mg·g–1·min–1. useful species are studied assigned •O2–, 1O2, h+. effect coated for photocatalytic over photoelectrochemical experiments, fluorescence spectra, density functional theory (DFT) calculations. It attributed good conductivity carbon, enhanced separation photocarriers coating, thermodynamically favorable reactive oxygen (ROS) production surface carbon. demonstrates coating an effective strategy improve reveals detailed mechanism.

Published: March 18, 2025

A self-assembled supramolecular photocatalyst of benzoic acid-substituted perylenediimide (SA-BAPDI) is successfully prepared, forming an alternate stringlike morphology driven by intermolecular hydrogen-bonding and π-π interactions. This unusual induces a strong built-in electric field enormous π-conjugated effect, which can promote efficient separation photogenerated carriers. Meanwhile, SA-BAPDI applied as the photoanode in H2O2 photoelectrochemical cell for first time facilitate photocatalytic production water oxidation, be used fuel to generate electricity through redox reactions further achieve solar-chemical-electrical energy conversion. The SA-BAPDI-based displays maximum light power density 1.06 mW·cm-2 specific capacitance 5025 mF·cm-2 after 0.5 h irradiation, still retain original value 50% dark 12 continuous operation. study verifies that regulation materials benefits design development high-performance cell.

Modulating the Photocatalytic Capability of Organic Small Molecule Semiconductors for the Degradation of Different Antibiotics via Self-Assembly and Inorganic Hybridization

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: April 12, 2025

This study introduces a perylene diimide (PDI) small molecule in the photocatalytic degradation of antibiotics for first time. Initially, we optimized its photoelectric performance through self-assembly to obtain an n-type photocatalyst (SA-PDI). Subsequently, WO3 and Cu2O were incorporated using facile one-step method prepare n-n type n-p organic-inorganic hybrid photocatalysts (PDI-WO3 PDI-Cu2O). approach simultaneously achieved self-assembly, metal ion doping, inorganic hybridization, further modulating properties materials. Studies indicated that PDI-WO3 operates via type-II heterojunction mechanism, whereas PDI-Cu2O follows S-scheme mechanism. SA-PDI demonstrated superior efficiency toward tetracycline hydrochloride (TCH), while exhibited enhanced activity both TCH doxycycline (DOX). In contrast, showed higher efficacy ciprofloxacin (CIP) norfloxacin (NOF). These differences are attributed distinct active species generated by each catalyst, aligning with requirements specific antibiotics. Moreover, since all three materials based on PDI molecule, they inherently compatible. Consequently, directly mixed these composite simultaneous multiple simulated wastewater system, systematically investigated effects ions, humic acid, pH effectiveness treating antibiotic solutions. Ultimately, this provides novel design strategies demonstrates promising potential practical applications mitigating contamination real systems.
