However, the shortcomings such as a low specific surface and an unstable structure made it difficult to display an excellent electrochemical performance. To address the said problems, carbon fibers were grown in situ on foam nickel by CVD method to prepare a three-dimensional foam nickel/carbon fiber composite collector, and then nickel-cobalt hydroxides were obtained on the composite current collector by a hydrothermal method with the aim of a superior supercapacitor electrode material (CF/Ni–Co). Effects of anions of metal salts (such as acetate, nitrate, sulfate and chloride) on the morphology, structure and electrochemical performance of the obtained electrodes were investigated. The results suggested that the sample CF/Ni–Co(SO4) synthesized with nickel sulfate and cobalt sulfate possessed large specific surface area. It also displayed outstanding capacitive performance with a superb specific capacitance of 3675.6 F/g at 1 A/g, a high capacitance retention rate of 70.6% as the current density increased to 15 A/g, and a good cycling stability of 66.4% after 2000 cycles of charge-discharge at 15 A/g, demonstrating CF/Ni–Co(SO4) with the three-dimensional nickel foam/carbon fiber composite as current collector had great potential for high-performance supercapacitor electrode materials.","PeriodicalId":767,"journal":{"name":"Russian Journal of Physical Chemistry A","volume":"98 10","pages":"2371 - 2379"},"PeriodicalIF":0.7,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its surface morphology, optical absorption coefficient and photocatalytic activity are greatly improved compared with pure C3N4 and AlFeO3. Photocatalytic experiments confirmed that the C3N4/AlFeO3 photocatalyst showed high photocatalytic activity for degradation of methyl orange under visible light irradiation, and its degradation rate was 9.40 times that of C3N4 and 5.13 times that of AlFeO3. The optimal catalyst content, dye concentration and pH value are 1 g/L, 20 mg/L and 5, respectively. Capture and stability experiments confirmed that the C3N4/AlFeO3 photocatalyst is recyclable, and holes, hydroxyl radicals and superoxide radicals are the main active species in the photocatalysis process.","PeriodicalId":767,"journal":{"name":"Russian Journal of Physical Chemistry A","volume":"98 10","pages":"2380 - 2389"},"PeriodicalIF":0.7,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These versatile microspheres have great potential for further development. With the development of novel polymerization techniques, different types of nanometer polymer microspheres have been synthesized and more and more attention has been paid to their potential applications. In this study, nanometer polymer microspheres containing biphenyl formaldehyde were synthesized by Schiff base reaction. We used Tri(4-aminophenyl)amine and 4,4'-biphenyldicarboxaldehyde as reactants, a mixture of 1 : 4 DMF and ethanol as solvent, glacial acetic acid as catalyst, and reflux heating to obtain nanometer-polymer microspheres. We also evaluated the adsorption performance of these microspheres using methyl orange as a simulated pollutant. We conducted a single factor experiment to investigate the effects of different ratios, dosages, times, and temperatures on adsorption efficiency. We characterized the nanometer-polymer microspheres by XRD, IR, and SEM techniques to examine their size, morphology, and structure. Experimental results showed that the optimal ratio for nanometer-polymer microspheres was 1 : 2, with an optimal dose of 25 mg. The optimal adsorption conditions were a temperature of 30°C and a time of 60 min. Since the pH of the solution ranged from 3 to 8, the zeta potentials of microspheres had a negative value. Meanwhile, zeta potentials became more negative as pH increased. The adsorption equilibrium data fit well with the Freundlich model. The microspheres had a stable and uniform rigid structure and good regeneration performance, with regeneration efficiency higher than 80% after five adsorption-desorption cycles.","PeriodicalId":767,"journal":{"name":"Russian Journal of Physical Chemistry A","volume":"98 10","pages":"2313 - 2323"},"PeriodicalIF":0.7,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
