C3H6

1

The catalytic activity of the catalyst in CO 、 C3H6 and NO was investigated . The relationship between the catalytic activity and the structure of catalyst was always explored by means of X-ray diffraction , scanning electron microscopy .

考察了该催化剂对CO、C3H6和NO的催化转化性能，并借助扫描电子显微镜（SEM）、X-射线衍射（XRD）等方法研究了催化剂活性与结构的关系。

With the decreasing of P_ ( N2 ) / P_ ( C3H6 ), pyrocarbon deposition mode has the trend that changes from surface chemical reaction nucleation-growth mode to vapor nucleation-growth , and the pyrocarbon surface becomes rough .

随P（N2）／P（C3H6）降低，热解碳沉积模式有从表面化学反应成核.生长向气相成核.生长模式转化的趋势，沉积热解碳层随之变得粗糙。

The effect of deposition temperature , system pressure and P_ ( N2 ) / P_ ( C3H6 ) on the pyrocarbon morphology and deposition rate was studied . The results show that the pyrocarbon morphology can be governed by variation of the above parameters .

结果表明：沉积温度、系统压力和P（N2）／P（C3H6）均会使热解碳沉积形貌发生变化。
