Catalyst activity was determined by not only specificsurface area of catalyst but also the distributions of active center and utilization ratio of internal surface.
催化剂活性不仅与比表面有关,还与其活性中心分布情况、内表面利用率有关。
2
The specificsurface area of catalyst decrease with preparing temperature increasing.
比表面积随催化剂制备温度和制备时间的增加而减小。
3
The obtained catalyst has high specificsurface area, pore volume and content of the zero-valent iron; and the iron is uniformly distributed on the surface of carbon and has favorable stability.
