Metal−organic frameworks (MOFs) have extensively emerged as promising templates/precursors to prepare functional derivatives for various purposes because of their ultrahigh porosity, large specific surface area, and excellent user-configuration flexibility. Among these derivatives, MOFs-derived metal/carbon composites surmount the shortcomings of the individual components and produce synergistic effects, showing great potential in environmental remediation and energy storage and conversion. Herein, this work systematically discusses the synthetic strategies of MOFs-derived metal/carbon composites from the perspective of different MOF precursors, including pristine MOFs, heteroatom-doped MOFs, and MOFs composited with substrates. The unique advantages of MOFs-derived metal/carbon composites with exceptional stability, conductivity, and catalytic activity are then particularly summarized. On the basis of these advantages, their recent progress in the environment and energy fields is elaborated, with special emphasis on the elucidation of their mechanisms. Finally, the challenges and opportunities for future research are presented, which is expected to provide references for the design of multipurpose MOFs-derived metal/carbon composites.

Understanding the Iron-Cobalt Synergies in ZSM-5: Enhanced Peroxymonosulfate Activation and Organic Pollutant Degradation

et al. 2022

Iron- and cobalt-based heterogeneous catalysts are widely applied for activating peroxymonosulfate (PMS) to degrade organic pollutants. However, few studies have unveiled the clear synergistic mechanism of iron and cobalt in ZSM-5. In this paper, the synergistic mechanism of enhanced PMS activation was revealed by constructing iron and cobalt bimetal modified ZSM-5 zeolite catalysts (FeCo-ZSM-5). The tetracycline hydrochloride (TCH) degradation experiments showed that the catalytic activity of FeCo-ZSM-5-2:3 was much higher than those of Fe-ZSM-5 and Co-ZSM-5. In addition, the influences of catalyst dosage, PMS concentration, reaction temperature, initial pH, and coexisting ions on TCH removal were systematically investigated in this paper. Density functional theory calculations indicated that Co was the main active site for PMS adsorption, and Fe increased the area of Co’s positive potential mapped to the electron cloud. The Fe–Co bimetallic doping increased the area of positive potential mapped to the electron cloud and benefited the adsorption of PMS on the catalyst surface, which revealed the synergistic mechanism of bimetals. Electron paramagnetic resonance spectra and quenching experiments showed that sulfate radicals, singlet oxygen, and hydroxyl radicals were involved in the degradation of TCH. Furthermore, liquid chromatography–mass spectrometry was conducted to propose possible degradation pathways. This work provides certain guiding significance in understanding the synergistic effect of heterogeneous catalysts for tetracycline wastewater treatment.
