摘　　要：采用重铬酸钾和过氧化氢为氧化剂,浓硫酸、乙酸酐和钛酸四正丁酯为插入剂,水洗、干燥、高温膨化法,成功地将膨胀石墨的制备方法与二氧化钛的制备方法相结合。嵌入后膨胀石墨的膨胀体积为280ml/g。实验证明了该材料不仅具有物化吸附性能,还可进行农药污水的降解。Double potassium dichromate and hydrogen peroxide Were used as oxidant, and sulfuric acid, acetic acid anhydride and tetra-n-butyl titanate were used as inserting substance, and then washing, drying,heating rapidly at high temperature was needed. That triumphantly combined the preparation of the exfoliated graphite with that of TiO2. The volume of prepared exfoliated graphite is 280ml/g. In our experiment, this material had capability of not only physics and chemical adsorption, but also photocatalysis for insecticide.
