Sol-Gel法制备氧化铝负载铜基超细粒子影响因素的研究

Influence Factors Study of Alumina Supported Copper Ultrafine Particle by Sol-Gel Method

通过对Sol-Gel法制备氧化铝负载铜基超细粒子的研究,表明PEG分散剂对粒度分布有重要影响;采用XRD对制得的催化剂表面组成进行了研究,指出了发生固相反应生成活性较低的CuAl2O4的影响因素。

Alurnina supported copper ultrafine particle by sol-gel method were studied. The results showed that PEG dispersant had important impact on granularity distribution; the surface constitution of catalyzer was analyzed by XRD and the influence factors that producing low active GuAl2O4 in the solid state reaction were pointed out.
