The rational integration of conductive RGO, magnetic CoFe₂O₄, and Ag–AgBr enables efficient visible-light harvesting, interfacial charge separation, and preserved redox activity. The composite was thoroughly characterized using FTIR, XRD, SEM, TEM, and XPS, confirming its successful fabrication and structural stability. The composite exhibits a narrow band gap of 2.26 eV and demonstrates superior suppression of charge-carrier recombination. Consequently, the photocatalyst achieved a high cetirizine degradation efficiency of 93.36% within 1 h. Band-structure and radical-scavenging studies supported a <em>Z</em>-scheme charge-transfer mechanism, with hydroxyl radicals (•OH) identified as the primary species responsible for pollutant breakdown. The photocatalyst performed optimally at pH 6, while humic acid concentrations below 2 ppm showed minimal impact on efficiency. LC–HR–MS analysis validated effective degradation and mineralization, allowing the proposal of a plausible reaction pathway. In addition, the composite exhibited strong antibacterial activity against <em>Bacillus subtilis</em>, <em>Staphylococcus aureus</em>, <em>Escherichia coli</em>, and <em>Salmonella typhi</em>. Overall, the multifunctional RGO/CoFe₂O₄/Ag–AgBr nanocomposite shows excellent potential for sustainable water treatment through simultaneous chemical pollutant removal and microbial control.</div></div>","PeriodicalId":13609,"journal":{"name":"Inorganic Chemistry Communications","volume":"186 ","pages":"Article 116279"},"PeriodicalIF":5.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146170141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired from nature, design and developing metal porphyrins is a very attractive solution. However, the activity and selectivity of metal porphyrins still need to be improved. During the ORR process of metal porphyrins, the breaking of O<img>O bond to form M-oxo species, is crucial. Hence, the ease of forming M-oxo species determines the selectivity of ORR. Early transition metals, such as Mn and Fe, readily form M-oxo species, favoring the 4e⁻ pathway. In contrast, late transition metals have difficulty forming M-oxo species, making the catalytic cleavage of O<img>O bond less likely and thus favoring the 2e⁻ pathway. Given that Co-oxo species possess suitable stability and reactivity, mononuclear Co centers can theoretically catalyze both 2e⁻ and 4e⁻ ORR, with the selectivity largely dependent on the electronic structure of Co and its surrounding environment. In this work, we designed Co porphyrin <strong>2</strong> with a pyridyl group, Co porphyrin <strong>1</strong> with a chlorine atom connected to the single adjacent nitrogen atom of pyridyl group, and Co porphyrin <strong>3</strong> without a pyridyl group to study the influence of pyridyl group on electrocatalytic ORR under acidic conditions. Experimental results demonstrate that pyridyl significantly enhances ORR activity and selectivity. Upon the addition of trifluoroacetic acid at the same concentration in homogeneous catalysis, the catalytic current of <strong>2</strong> was 1.8 times of Co porphyrin <strong>1</strong> and 4.5 times of Co porphyrin <strong>3</strong>, with an earlier onset potential and higher turnover frequency (TOF) value.

In this case, the issue was tackled using a self-synthesized ionic liquid (1-Dodecyl-3-methylimidazolium chloride) as the electrolyte, resulting in the creation of a MIL-53(Al) structure similar to the one obtained through solvothermal synthesis. A comprehensive parametric analysis was performed, taking into account the influence of different factors such as solvent composition, reaction time, cell voltage, electrode surface area/cell volume ratio, and cell temperature on both cell efficiency and CO₂ adsorption capability. Different techniques were used for characterizing both samples to determine their physicochemical properties including X-ray diffraction, BET analysis, FTIR, TGA, and SEM. The parametric analysis demonstrated that the key synthesis parameters influencing CO₂ adsorption capacity were cell voltage, cell temperature, and the electrode surface area/cell volume ratio. The findings also showed that the highest CO₂ absorption of 6.07 mmol/g was obtained from the ZIF-8 produced under the optimized conditions, while the maximum quantity of CO₂ captured by the optimized MIL-53(Al) sample was 3.89 mmol/g in the identical electrochemical cell.
