Through changing carbonization temperature, mesoporous carbon/silica hybrid samples with different BET surface areas and pore size distributions were obtained. The materials were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Thermo Gravimetric Analyzer (TGA) and nitrogen adsorption-desorption analysis. The results showed that carbonization temperature would directly influence the pore structure. When the carbonization temperature is 850℃, the mesoporous carbon/silica hybrid material with perfect orderliness and narrow pore size distribution can be prepared.      ZTFLH:  O613   服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y2013/V27/I4/385 [1] 李福禄, 韩春淼, 高嘉望, 蒋健, 许卉, 李冰. 氧化石墨烯的变温发光[J]. 材料研究学报, 2022, 36(8): 597-601.
