High surface area porous silicon carbide synthesized via sol-gel and carbothermal reduction process 作者: Wang DH (Wang, Dong-Hua) 來源出版物: JOURNAL OF OPTOELECTRONICS AND ADVANCED MATERIALS 卷: 13 期: 2-4 頁: 218-222 出版年: MAR 2011 被引頻次: 0 參考文獻: 18 引證關(guān)系圖 摘要: A modified sol-gel method is proposed for the preparation of high surface area porous silicon carbide. In this method, furfuryl alcohol and tetraethoxysilane were used respectively as carbon and silicon precursors for preparing a carbonaceous silica xerogel. Polymethylhydrosiloxane (PMHS) was employed as pore-adjusting agent in the sol-gel process. SiC was obtained by the carbothermal reduction of the carbonaceous silica xerogel at 1300 degrees C in argon flow and then purified by removing excess silica, carbon and other impurities. XRD, FTIR, SEM, HRTEM and BET were used to characterize the SiC samples. The results show that the SiC products are found to have high specific surface area of 167 m(2)/g. PMHS has important effect on the surface area, pore volume of the SiC products. The SiC exhibits different photoluminescence properties. 文獻類型: Article 語言: English 作者關(guān)鍵詞: Sol-gel; Polymethylhydrosiloxane; High surface area silicon carbide; Carbothermal reduction; XRD; FTIR; SEM; HRTEM; BET KeyWords Plus: FABRICATION 通訊作者地址: Wang, DH (通訊作者), Weinan Teachers Univ, Dept Chem & Chem Engn, Weinan 714000, Peoples R China 地址: 1.
