Abstract:in the work,the novel CuO-ZnO catalysts have been prepared by precipitation method for water gas shift reaction. The effect of temperature and copper content on the performance of catalysts has been investigated in detail. The XRD BET and TPR technology has been employed to analyze the specific surface area of catalysts. The results indicate: the activity of catalysts increase with increasing of copper content. However the activity of catalysts is independent of surface area of ZnO. The highly activity of catalysts can be attributed to nano- copper crystalline.

摘要:本文用两步法制备了新型光电聚合物材料并测试了其光电转化效率等性能。典型的制备过程如下:首先将10mL的乙醇和50mL的甲酸加入到反应器中,然后在剧烈搅拌下将氢氧化钠溶解于上述体系中,在催化剂存在下70摄氏度下搅拌三小时。产品经过蒸馏、洗涤、结晶、真空干燥得到。详细考察了反应温度、催化剂用量、反应浓度对产品性能的影响。应用BET技术分析了固体产品的比表面积。结果表明:随着反应时间的延长,产品收率提高;而所得聚合物的性能与催化剂的孔隙率无关,所得聚合物效率高的原因是催化剂活性高。

? 摘要:近年来,氢能和燃料电池吸引了科学家们越来越多关注。几年来BASF的科学家提出了高效而简单可行的制备方法来制备铂(Pt)催化剂用于乙醇重整反应。然而,该铂(Pt)催化剂催化剂存在着成本高昂的缺点。本文采用浸渍(impregnant)法制备了新型氧化铝负载的纳米镍催化剂并评价了其在乙醇水蒸气重整反应中的性能。典型的制备过程如下:首先将氧化铝粉体分散于50mL乙醇和50mL水混合溶液中,然后在剧烈搅拌下将硝酸镍溶液滴加到上述体系中, 70摄氏度下搅拌三小时。纳米镍催化经过过滤、洗涤和干燥得到。详细考察了镍含量、制备问题、反应时间对纳米镍催化剂性能和纳米镍晶粒尺寸的影响。应用BET技术表征了催化剂的比表面积。结果表明:随着镍含量的增加,催化剂活性提高;所得催化剂具有高活性的原因可以归结为催化剂表面上存在着纳米镍。

? Abstract: In recent years, more and more attentions have been paid on hydrogen energy and fuel cell. (用absorb much interests 句式也对,用其他句式也可以,只要意思对写作对就可以)A effective and straightforward preparation method for Pt catalyst have been proposed by the scientists of BASF group. However, this kind of Pt catalyst has an obvious drawback of high costs. In this paper,
