为了进一步提高直接乙醇燃料电池催化剂的性能,在800℃下碳化聚吡咯包覆的蒙脱土,制备碳包覆蒙脱土复合载体.通过多醇还原法在其表面沉积铂纳米颗粒,并考察碳包覆蒙脱土复合载体在电催化乙醇氧化反应中的效果.所制备的样品用X射线衍射仪、扫描电镜、透射电镜和X射线光电子能谱分析了物相结构、表面形貌和组成.电化学结果表明,所合成的碳包覆蒙脱土负载铂催化剂比商业碳（Vulcan XC-72）载铂催化剂具有较大的电化学面积和电催化乙醇氧化活性.

甘南地区不同生境西藏沙棘根际土壤可培养硝化细菌多样性研究

为了解西藏沙棘根际土壤可培养硝化细菌的多样性,分析研究了甘南地区三个样地西藏沙棘根际土壤中的硝化细菌.结果共分离得到32株硝化细菌,分属于4个属.硝化细菌数量最多的是样地T5-1,为每克干土(5.69±0.81)×10~5 CFU;样地T5-2硝化细菌最少,为每克干土(0.43±0.06)×10~5 CFU;样地T5-3的硝化细菌数量介于样地T5-1和T5-2之间,为每克干土(4.29±0.42)
