负载二氧化钛的膨胀石墨的制备及表征
The Preparation and Analyzed of an Exfoliated Graphite Inserting TiO2
【摘要】 将干燥的天然鳞片石墨、浓硫酸、重铬酸钾、乙酸酐、过氧化氢和钛酸四正丁酯混合搅拌,洗涤,烘干,在高温下膨化制备得到具有光催化作用的吸附材料负载二氧化钛的膨胀石墨。并利用能谱、SEM、XRD等方法对二氧化钛膨胀石墨进行分析和表征。
【Abstract】 Dry natural graphite, 98% sulfuric acid, dry potassium dichromate, acetic acid anhydride, hydrogen peroxide and tetra-n-butyl titanate are stirred and reacted together,and dried,heated rapidly at high temperature, then the exfoliated graphite inserting TiO2 is obtained and it is analyzed and characterized by energy spectrum, SEM, and XRD.
