将磁性基质Co0 .5Fe2 .5O4与ZrO2 进行组装制备出磁性固体酸催化剂 ,采用TEM、DTA、XRD、FTIR等手段对Co0 .5Fe2 .5O4/ZrO2 磁性固体酸催化剂的结构和性能进行了研究。结果表明磁性基质的引入延迟了ZrO2 的晶化以及ZrO2 (t)相向ZrO2 (m)相的转变 ,使ZrO2 更加稳定。我们合成的Co0 .5Fe2 .5O4/ZrO2 粒径在 40nm左右 ,且具有良好的催化性能和适宜的磁学性能
The magnetic solid Co0.5Fe2.5O4 and ZrO2 were assembled to prepare magnetic solid acid catalyst. The structure and properties of Co0.5Fe2.5O4 / ZrO2 magnetic solid acid catalyst were studied by means of TEM, DTA, XRD and FTIR. The results show that the introduction of magnetic matrix delayed the crystallization of ZrO2 and the transformation of ZrO2 (t) to ZrO2 (m), which made ZrO2 more stable. Our synthesized Co0 .5Fe2 .5O4 / ZrO2 particle size of about 40nm, and has good catalytic properties and suitable magnetic properties
