To realize the practical supercapacitors, developing the cheap and highly capacitive electrode is the most essential. However, it is a harsh challenge to achieve this target based on single-component electrode. Herein, a series of inexpensive ternary-metal-sulfides, 2MnS/Cu<sub>2</sub>S/<em>x</em>ZnS/C (<em>x</em> = 0, 0.5, 1, 2, 3) are synthesized by hydrothermal reaction and the subsequent calcination with expired manganese/copper gluconates as the raw materials for the electrode in the pseudocapacitors. Furthermore, the effect of ZnS's content on the electrochemical properties of the ternary composites is also investigated. Specially, the optimal 2MnS/Cu<sub>2</sub>S/xZnS/C(<em>x</em> = 1) can output a specific capacitance of 1608 F/g at 1 A/g in the three-electrode system, while the 2MnS/Cu<sub>2</sub>S/xZnS/C||AC(<em>x</em> = 1) asymmetric supercapacitor can deliver a specific capacitance of 194 F/g at 1 A/g with the desirable energy density (800 W/kg) and power density (70.9 Wh/kg), higher than those of other samples.

The complex was characterized by various spectroscopic techniques, including FT-IR, UV-Vis spectroscopy, elemental analysis, TG-DTA, and conductivity measurements. X-ray crystallography confirmed the formation of the binuclear complex, revealing a dicationic unit with distorted octahedral geometry at the copper centers, bridged by two chloride ions. The coordination environment around each copper ion includes two nitrogen and two oxygen donors from the ligand, along with the bridging chlorides. Notably, the complex exhibits significant chromotropism, including solvatochromism, halochromism, ionochromism, and thermochromism, which are attributed to the Jahn-Teller effect and the flexible coordination environment around the copper centers. Thermal analysis indicates the stability of the complex up to 118°C, with subsequent decomposition occurring in distinct stages.

The chemisorption of GGL via hydroxyl and carbonyl groups on the Al<sub>12</sub>N<sub>12</sub> surface resulted in an enhanced the dipole moment and binding energy (E<sub>bin</sub>) in the water phase compared to methanol and dichloromethane phases at the CAM-B3LYP method. This adsorption process resulted in slight shifts in the electronic structure of all the complexes. Adsorption analysis revealed that the hydroxyl group of GGL, unlike its carbonyl group, exhibits strong interactions with the B atom in Al<sub>11</sub>BN<sub>12</sub>, the Mg atom in Al<sub>11</sub>MgN<sub>12</sub>, and the Ga atom in Al<sub>11</sub>GaN<sub>12</sub> fullerene-like cages. The Al<sub>11</sub>MgN<sub>12</sub> and Al<sub>11</sub>BN<sub>12</sub> fullerene-like cages exhibit weaker binding energies compared to Al<sub>11</sub>GaN<sub>12</sub>, resulting in shorter desorption times. This facilitates the delivery of GGL and increases its dipole moment, thereby enhancing its solubility. Additionally, GGL loaded onto Al<sub>11</sub>MgN<sub>12</sub> increases hardness, electronegativity, and electrophilicity while decreasing softness, indicating enhanced stability and interaction capabilities. Moreover, Al<sub>11</sub>MgN<sub>12</sub> exhibits high sensitivity to GGL molecules as a biosensor, owing to significant shifts in its energy gap compared to Al<sub>11</sub>GaN<sub>12</sub> and Al<sub>11</sub>BN<sub>12</sub> cages. Theoretical infrared (IR) spectroscopy calculations indicate changes in vibration frequencies due to GGL adsorption onto fullerene-like cages. Overall, the findings suggest that GGL-loaded Al<sub>11</sub>MgN<sub>12</sub> has promising potential for improving solubility and efficacy in drug delivery systems for biological applications.</div></div>","PeriodicalId":16414,"journal":{"name":"Journal of Molecular Structure","volume":"1324 ","pages":"Article 140787"},"PeriodicalIF":4.0,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720930","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}
