为了从催化剂的化学和物理性质来说明它的催化性能,在研制化肥催化剂的过程中,我们曾经使用X射线分析法、热分析法、表面积与孔结构测定、光学显微镜与电子显微镜的观察、电子探针分析、穆斯鲍尔效应测定等对催化剂进行了一些测定工作。其中,从X射线分析所获得的关于物相组成、晶格参数和晶粒度等晶体结构数据,对于剖析催化剂,选择催化剂制备条件,研究催化剂失活原因以及探讨助催化剂等方面,都发挥了较大的作用。一、剖析催化剂在研制催化剂的工作中,通常要选出一些同类型样品,进行比较。利用各种分析工具,比较全面地测定这些催化剂的化学组成、
In order to elucidate its catalytic properties from the chemical and physical properties of catalysts, we used X-ray analysis, thermal analysis, surface area and pore structure determination, optical and electron microscopy observations, electron Probe analysis, Moose Bauer effect determination of the catalyst for some of the determination. Among them, the crystal structure data on the phase composition, lattice parameter and grain size obtained from the X-ray analysis have played an important role in analyzing the catalyst, selecting the preparation conditions of the catalyst, studying the reason of the catalyst deactivation and exploring the cocatalyst Greater effect. First, the analysis of the catalyst In the development of the catalyst, usually to select some of the same type of samples for comparison. The use of a variety of analytical tools, a more comprehensive determination of the chemical composition of these catalysts,
