Singlet‐Oxygen‐Driven Cooperative Photocatalytic Coupling of Biomass Valorization and Hydrogen Peroxide Production Using Covalent Organic Frameworks

Angewandte Chemie International Edition, Journal Year: 2025, Volume and Issue: unknown

Published: March 11, 2025

Abstract Traditional H 2 O photocatalysis primarily depends on photoexcited electrons and holes to drive oxygen reduction water oxidation, respectively. However, singlet ( 1 ), often underappreciated, plays a pivotal role in production. Meanwhile, photocatalytic biomass conversion has attracted attention, yet studies combining synthesis with valorization remain rare typically yield low‐value products. Herein, strategy of furfuryl alcohol (FFA) coupled the efficient co‐production is reported, enabled by covalent organic frameworks (COFs) induced, ‐participated Achmatowicz rearrangement. This study introduces polyimide‐based COF‐N 0‐3 tailored nitrogen content, representing an unprecedently platform for Remarkably, reducing content COF enhances production, significantly boosting generation rate. In FFA, primary pathway production rearrangement, achieving rate ten times higher than that reliant reaction pure water, reaching 4549 µmol g⁻¹ h⁻¹. Mechanism revealed selectively engaged bypassing hole oxidation trigger producing valuable 6‐hydroxy‐(2H)‐pyranone 99% 92% selectivity. work establishes coupling simultaneous biochemicals, offering transformative approach sustainable photocatalysis.

Enhanced Selectivity in PMS Activation via Non-Metal Doping for Efficient ¹O₂ Generation in Emerging Organic Pollutants Degradation

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 30, 2024

The activation of peroxymonosulfate (PMS) to generate singlet oxygen (1O2) for the removal emerging organic pollutants (EOPs) from complex aqueous environments has garnered widespread attention. However, low efficiency and selectivity current PMS 1O2 generation result in suboptimal EOP degradation. To enhance promote non-radical pathway, non-metal heteroatoms with varying electronegativities were introduced disrupt symmetrical coordination structure Fe active sites single-atom catalysts. results showed that, B-Fe1/GLCNs/PMS system, pseudo-first-order kinetic rate bisphenol A (BPA) degradation reached 4.435 min–1, which is 7.4 times higher than that unmodified control group. Experimental theoretical calculations demonstrated doping altered electron density distribution at sites, thereby modulating adsorption configuration HSO5– increasing 1O2. Additionally, EOPs by produced intermediate products lower biological toxicity, strong anti-interference capability. change morphology improved generation. This study provides deep insights into designing high-performance catalysts via regulate electronic a selective pathway.
