Synergistic Bifunctional Covalent Organic Framework for Efficient Photocatalytic CO₂ Reduction and Water Oxidation

Journal of the American Chemical Society, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

The scientific community has been actively researching artificial photosynthesis to promote ecologically sustainable living and address environmental issues. However, designing photocatalysts with active sites that are effective for both CO2 reduction water oxidation remains a significant challenge. Thus, we present the development of donor-acceptor covalent organic framework (D-A COF), integrates two distinct metal coordination environments through structure-activity relationships. Either cobalt or nickel ion is anchored on D-A COF backbone create N-metal-nitrogen N-metal-sulfur configurations, serving as bifunctional sites, respectively. Remarkably, as-synthesized Co-Btt-Bpy generated CO at rate 9,800 μmol g-1 h-1 O2 242 under visible light irradiation. generation was 127 times higher than pristine COF. More importantly, facilitates release 7.4 h-1. outstanding photocatalytic performance can be attributed synergistic interaction between dispersed single-atom Btt-Bpy COF, well rapid migration photogenerated electrons. In situ attenuated total reflection Fourier transform infrared (ATR FT-IR) spectra theoretical calculations indicated introducing Co effectively lowered reaction energy barriers crucial intermediates *COOH *OH. This work provides state-of-the-art designs molecular level in-depth insights efficient photosynthesis.

Simultaneous Heavy‐Metal Ion Adsorption and Electricity Generation From Wastewater via “Heavy‐Metal Removal Batteries”

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 2, 2025

The heavy-metal ion in wastewater is a great threat to the health of both humans and ecosystems. common removal strategies usually suffer from energy consumption poor recyclability. Herein, battery designed by constructing two-chamber configuration. Such displays capacity simultaneous adsorption electricity output, where driven potential difference between electrodes metal electrodes, generated continuously during process. Significantly, various ions (e.g., Mn2+, Co2+, Ni2+, Zn2+, Cr3+ Pb2+ ions) can be removed due large lattice spacing active materials displaying universality adsorbing wastewater. In addition, an environmental-friendly chemical oxidation strategy developed desorb which not only produces high-quality salts, but also reduces toxicity sludge case secondary pollution. Impressively, these batteries easily scaled up integrated extend ability voltage/current output. This work proves creative approach for generation
