摘　　要：采用水浴法,用仲钨酸铵饱和溶液浸渍竹炭,经煅烧,沉积物分解。循环多次,制备出优质碳基和分布均匀的钨氧化物,为制备性能良好的竹基碳化钨奠定基础。采用XRD、SEM对其形貌和结构进行分析,结果表明,分解产物为钨的氧化物,颗粒分布均匀,可用于催化剂载体。The captioned precursor was prepared by water bath process according to which Bamboo charcoal was soaked with APT saturated solution. The morphology and structure of the precursor were analyzed by means of XRD and SEM. The results show that the products of the decomposition are tungsten oxides, which, in the form of uniformly distributed particles, can be used as the carrier for the catalyst.
