In Situ Pyrolysis of ZIF-67 to Construct Co₂N_0.67@ZIF-67 for Photocatalytic CO₂ Cycloaddition Reaction

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: unknown

Published: July 26, 2024

The development of heterogeneous catalysts with abundant active sites is pivotal for enhancing the efficiency photothermal CO2 conversion. Herein, we report construction Co2N0.67@ZIF-67 through in situ pyrolysis ZIF-67 under low-temperature conditions. During process, crystal structure predominantly preserved concurrently formation Co2N0.67 nanoparticles (NPs) within pores. optimal catalyst Co2N0.67@ZIF-67(450,2) not only possesses high but also can efficiently activate CO2. Benefiting from these characteristics, exhibited significant catalytic activity photocatalytic cycloaddition and epichlorohydrin. yield (chloromethyl)ethylene carbonate reached 95%, which more than 4 times higher that visible light irradiation (300 W·m2 Xe lamp, 3 h). This study could offer an alternative approach to enhance MOFs pyrolysis.

Rational Design and Synthesis of Fe-Doped Co-Based Coordination Polymer Composite Photocatalysts for the Degradation of Norfloxacin and Ciprofloxacin

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(14), P. 6514 - 6525

Published: March 28, 2024

The solar light-responsive Fe-doped Co-based coordination polymer (Fe@Co-CP) photocatalyst was synthesized under mild conditions. [Co(4-padpe)(1,3-BDC)]n (Co-CP) first constructed using mixed ligands through the hydrothermal method. Then, Fe introduced into Co-CP framework to achieve enhanced photocatalytic activity. optimal Fe@Co-CP-2 exhibited excellent catalytic degradation performance for norfloxacin and ciprofloxacin sunlight irradiation without auxiliary oxidants, rates were 91.25 92.66% in 120 min. These properties ascribed generation of Fe–O bond, which not only light absorption intensity but also accelerated separation efficiency electrons holes, hence significantly improved property composites. Meanwhile, displayed stability reusability. In addition, pathways intermediates antibiotic molecules effectively analyzed. free radical scavenging experiment ESR results confirmed that •OH, •O2–, h+ active species involved reaction; corresponding mechanisms deeply investigated. This study provides a fresh approach constructing Co-CP-based composite materials as photocatalysts contaminants.
