Anthraquinones-based photocatalysis: A comprehensive review

Environmental Science and Ecotechnology, Journal Year: 2024, Volume and Issue: 22, P. 100449 - 100449

Published: July 5, 2024

In recent years, there has been significant interest in photocatalytic technologies utilizing semiconductors and photosensitizers responsive to solar light, owing their potential for energy environmental applications. Current efforts are focused on enhancing existing photocatalysts developing new ones tailored uses. Anthraquinones (AQs) serve as redox-active electron transfer mediators photochemically active organic photosensitizers, effectively addressing common issues such low light utilization carrier separation efficiency found conventional semiconductors. AQs offer advantages abundant raw materials, controlled preparation, excellent capabilities, photosensitivity, with applications spanning the energy, medical, sectors. Despite utility, comprehensive reviews AQs-based systems contexts lacking. this review, we thoroughly describe photochemical properties of photocatalysis, particularly key challenges like clean production, antibacterial action, pollutant degradation. However, face limitations practical due electrical conductivity solubility-related secondary contamination. To mitigate these issues, design synthesis graphene-immobilized highlighted a solution enhance Additionally, future research directions proposed deepen understanding AQs' theoretical mechanisms provide wastewater treatment. This review aims facilitate mechanistic studies improve technologies.

Utilizing photocatalytic technology to achieve efficient production of H2O2 is a hot topic. Here, we synthesized material with strong built-in electric field, namely, Pym-CN, through hydrothermal-assisted thermal polymerization strategy, which effectively promotes the separation and transfer photoinduced charge carriers. A pyrimidine ring was successfully introduced into heptazine structure unit leads electron aggregation at N═C–N, benefiting for enhancing sorption activation capabilities oxygen. Under condition visible light wavelength greater than 400 nm (λ > nm), rate Pym-CN (2622.5 μmol/L/h) 7.6 times that BCN. detailed investigation reaction mechanism revealed follows two-step continuous process single-electron oxygen reduction (ORR). This work elucidates application prospects donor–acceptor (D–A) field in H2O2.
