Study on Thermal Stability of γ-Al2O3 Powders Modified by Samarium Doping AITranslate
Abstract AITranslate
Using aluminum nitrate(Al(NO3)3·9H2O)as the oxidizing agent,glycine(C2H5NO2)as the reducing agent,and samarium nitrate(Sm(NO3)3·6H2O)as the modifier,γ-Al2O3 powders were synthesized by solution combustion method.The products were characterized by XRD,SEM,BET and TG-DTG.The effects of roasting temperature and modifier addition on the phase of the products were analyzed and discussed.The experimental results show that theγ-Al2O3 powders with high thermal stability could be prepared under the molar ratio of aluminum nitrate(Al(NO3)3·9H2O)to glycine(C2H5NO2)of 3∶5,addition of modifier Sm(NO3)3·6H2O of 1%,roasting temperature of 1025℃,and roasting time of 4 h.And theγ-Al2O(3)powders have the characteristics of large specific surface area and stable structure,which can be used as the carrier of catalyst.
