Facile hydrothermal carbonization with ZnCl<sub>2</sub>/FeCl<sub>3</sub> and physical activation were employed in addition. The physicochemical and energy storage properties of the graphitic carbons were investigated using Field Emission Scanning Electron Microscope (FESEM), N<sub>2</sub> adsorption-desorption, Brunauer-Emmett-Teller (BET), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Raman spectroscopy, Cyclic Voltammetry (CV), Galvanostatic Charge-Discharge (GCD) and Electrochemical Impedance Spectroscopy (EIS). Biomass modification by radiolytic oxidizing species aided in improving the energy storage properties of the resultant ACs without significantly changing the textural qualities. The radiation type played an important role on the surface functional groups, basal plane, and pore structures of the graphitic materials. The energy storage mechanism was based on a combination of EDLC and pseudo capacitances with high Coulombic efficiency. The highest specific capacitance obtained was 325.20 F/g providing capacity retention of 94.79 % after 10,000 cycles. A promising method of AC production for energy storage application has therefore been successfully demonstrated.</p></div>","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"7 2","pages":"Article 100192"},"PeriodicalIF":6.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588913323000546/pdfft?md5=14c07abc1b70c7c00d0075e78bf4aa7d&pid=1-s2.0-S2588913323000546-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47375788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is found that the obtained composite had higher photocatalytic activity than pure Cu<sub>2</sub>O. Particularly, 25 wt% N-DSC/Cu<sub>2</sub>O composite showed the highest photocatalytic performance with 95 % of TC degradation within 100 min and more excellent stability. Combined with various characterizations, it is confirmed that carbon bonds should be conducive to the separation of photoelectron and hole, and the carbon layer with an excellent electrical conductivity on Cu<sub>2</sub>O can reduce the charge transfer resistance between N-DSC and Cu<sub>2</sub>O, thereby improving the absorption of visible light and enhancing the photocatalytic activity. Moreover, it is considered that the synergistic effect of photo-generated electron pair in Cu<sub>2</sub>O and N-DSC could promote the photodegradation efficiency of N-DSC/Cu<sub>2</sub>O composite.

The catalytic performance and deactivation properties of MCM-22 zeolite in the oligomerization reaction of 1-hexene were investigated. Structure–activity relationships were established through the kinetic study. Although the density of strong acid sites was essential for the oligomerization of 1-hexene, the presence of low pressure was also necessary for the formation of dimers.
