In this study, using Co-MOF as a precursor, Co3O4-based catalysts rich in different concentrations of oxygen vacancies were successfully prepared through pyrolysis combined with sodium borohydride reduction and were employed for the efficient activation of peroxymonosulfate (PMS) to rapidly degrade oxytetracycline (OTC). The catalyst possessed excellent reaction kinetics, enabling rapid PMS activation and efficient OTC degradation. Radical quenching experiments and EPR analysis revealed that the degradation process follows a synergistic radical and nonradical mechanism, in which 1O2 and SO4•− play dominant roles. Furthermore, possible degradation pathways of OTC were proposed, and the ecotoxicity of its transformation products was evaluated. The results suggest that most intermediates have lower predicted toxicity than the parent compound.

Studies on OER electrocatalysis by using MMCs are primarily focused on the variation of transition metal composition. The electron structure in the kinetic behavior of MMCs has received little attention, let alone the control mechanisms of the electron structure modulation in kinetic behavior. In this work, we demonstrate a way to modulate the kinetic behavior by constructing the catalyst to obtain Ce-based multi-metal Prussian blue catalysts (CeMMPBA-x, x = usage ratios of Ce/(Ce + Ni + Co + Zn)) through regulating various usage ratios of Ce/(Ce + Ni + Co + Zn). Experimental tests demonstrated that when the usage ratio of cerium nitrate to other nitrate metals was 2:1:1:1, CeMMPBA-2 delivered an excellent electrocatalytic performance for OER, reaching 10 mA cm−2 with the potential at 1.49 V vs. RHE, respectively. Amazingly, CeMMPBA-2 also realized a negligible loss of activity even after 12 h in stability tests. Characterization results indicated that cerium facilitated the electron transfer from Ce to Fe/Ni sites through its distinctive 4f/5d electronic configuration and redox activity, which did a favor for CeMMPBA-2 to optimize the intermediate OH* adsorption, thereby enhancing its electrocatalytic ability to drive OER. This study gives new ideas on the design of multi-metal electrocatalysts with high efficiency to induce electron strategies to achieve high-entropy catalysts for energy conversion.\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"40 9","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148616969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents the rational design of biosourced mixed-metal cluster-based MOFs, Fe2M-fumarate (M = Cu, Zn, Mn), and isostructural with MIL-88A (Fe). The frameworks serve a dual purpose: as degradable micronutrient fertilizers that enable controlled metal release through the slow breakdown of secondary building units and as reservoirs for atmospheric moisture due to their water-adsorption characteristics. Physicochemical characterization confirmed the successful formation of homogeneous mixed-metal clusters, yielding spindle-shaped crystallites with distinct porosity profiles. Notably, the Fe2Cu–MIL-88A analogue exhibited a unique “breathing” behavior, achieving a remarkable water vapor uptake of ~630 mg g−1, significantly outperforming the Zn and Mn analogues. In contrast to the rapid dissolution characteristic of conventional salts, in vitro release assays revealed a biphasic profile, with a gradual initial release of Cu, Zn, or Mn, followed by a more sustained release of Fe, driven by hydrolytic matrix degradation. Kinetic modeling indicated that the Weibull model (R2 ≤ 0.98) best describes this complex mechanism, which combines erosion and diffusion. The release profiles can be tuned by varying the secondary metal within the trimeric cluster, illustrating the versatility of this approach. These findings position Fe2M–fumarate nanorods as a promising platform for moisture-responsive, sustained-release micronutrient delivery in agricultural environments.\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"40 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensing performance is based on the interactions between the APTMS-QDs@MOF and nitrate ions. The amine–Zn interaction and electrostatic interaction between negatively charged MOF and positively charged APTMS-QDs result in the quenching of APTMS-QDs due to an electron transfer process, along with the formation of the flower-like morphology of APTMS-QDs@MOF. When nitrate ions were introduced into the APTMS-QDs@MOF system, the quenching effect was reduced, resulting in a noticeable recovery of fluorescence. The fluorescence intensity increased proportionally with nitrate ion concentration, indicating good selectivity. The sensor exhibited a good linear response in the concentration range of 0.8–4.0 μM, with a detection limit of 0.295 μM. The sensing mechanism was further studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), and HR-TEM. The results revealed that nitrate ions weakened the interactions between the MOF and the APTMS-QDs, leading to a partial collapse of the MOF structure and recovery of fluorescence.
