摘要
堇青石(2Mg O2·Al2O3·Si O2)比表面积高、规整性强,以此为载体,涂敷Ti O2后,通过水热合成负载氯化钴,然后经过500℃焙烧及硼氢化钾(KBH4)浸渍,合成了负载型Co Ti O3/堇青石催化剂。利用X射线衍射(XRD)及X射线光电子能谱(XPS)对催化剂进行表征。催化实验研究表明,该催化剂经KBH4溶液浸渍后催化KBH4溶液水解析氢性能优良。
CoTiO3/cordierite catalyzer was synthesized with high specific surface area cordierite of clear and near as carrier, coating with TiO2 and loading cobalt chloride by hydrothermal synthesis, then baking at 500 ℃ and soaking in kalium borohydride （KBH4） solution. Character the catalyzer with X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. Experiment research shows that it has superior performance of hydrogen evolution after soaking in KBH4, and its performance of catalytic hydrolysis in alkaline KBH4 solution is better than the solution without alkali.
