摘　　要：采用激光固相热解反应法，以ＣＷＣＯ２激光作为辐照光源，成功地合成了ＣａＯ超精细粉末。实验结果表明：本法生成的粉末呈球状结构，粒径在２０～５０ｎｍ之间。激光多相催化１－庚烯反应使１－度烯异构化的转化率升高。并且使得顺式的相对含量大于反式的相对含量。CaO ultrafine powders were systhesized by CO2 laser solid-phase reaction method,with an CW CO2 laser as light source and Calcium carbonate as main row-material, IR, XPS and TEM were used to describe the characteristic of the powders. The experimental results showed that the powders were spherical, with narrow-size distribution and good uniformity. Their sizes are in the range of 20-50nm. The results that laser heterogeneous Catalyzes 1 hepten isomerization indicated that the conversion efficency of 1-hepten isomerization was raised and the raletively concentration of trans-2-hepted was higher than that of ets-2-hepten.
