Mn-O Covalency Governs the Intrinsic Activity of Co-Mn Spinel Oxides for Boosted Peroxymonosulfate Activation

Zhi-Yan Guo et al.

Summary: The covalency of TM-O bonds plays a critical role in governing the intrinsic catalytic activity of bimetallic spinel oxides, enhancing electron transfer and favoring interactions with PMS. By balancing PMS adsorption and metal reduction reactions, remarkable catalytic activities for PMS activation and pollutant degradation can be achieved, leading to the development of more active and robust metal oxide catalysts.

Preferential Growth of the Cobalt (200) Facet in Co@N-C for Enhanced Performance in a Fenton-like Reaction

Lipeng Wu et al.

Summary: In this study, a series of Co@N-C materials were synthesized using nitrates as templates to control the preferential growth of the cobalt (200) facet, exhibiting excellent activity for Fenton-like degradation of bisphenol A. The Co(200) facet was found to be the most active for PMS activation, with nitrates promoting its preferential growth. These materials showed higher stability and faster transformation rates, while singlet oxygen was found to play a dominant role in the degradation process. Density functional theory confirmed that Co nanoparticles coated with graphitic nitrogen-doped carbon had the best activity for PMS activation.

Photo-accelerated Co3+/Co2+ transformation on cobalt and phosphorus co-doped g-C3N4 for Fenton-like reaction

Xiaomei Liu et al.

Summary: Co and P co-doped g-C3N4 (Co, P-CN) synthesized by a facile one-pot pyrolysis method enhances light absorption and charge separation, promoting the photocatalytic activation of PDS. The chemical activation of doped Co2+ and the synergistic effect of photo-catalysis and chemical-catalysis result in the enhanced degradation of BPA with a reaction rate constant 7 times larger than pristine g-C3N4. This work provides an effective method for in situ regeneration of active low-valent transition metal ions and reveals the mechanism of synergistic activation of PDS for pollutant degradation.
