Textural properties of prepared alumina, stania and iron oxide catalysts Galal Elmanfe * Chemistry Department, Faculty of Science, Omar–AlMukhtar University, El-Beida, Libya *Email: galalmohamed1@yahoo.com DOI: https://doi.org/10.54172/mjsc.v29i1.265 Abstract Aluminum, Iron and Tin oxides were prepared by precipitation method using ammonia solution. The prepared gels were dried and calcined for three hours at 873 K to give the appropriate metal oxides Al 2 O 3 , Fe 2 O 3 and SnO 2 . These samples have been characterized by means of nitrogen adsorption at 77 K. Textural data obtained from N 2 adsorption show that alumina has higher surface area than other oxides indicating the presence of small particle size in alumina samples. Moreover, these oxides have mixed porosity ranging from micro and mesopores. The analysis of t- and α S curves shows the agreement between the values of specific surface area, S BET , S t and S S . Keywords: Alumina; Stania; Iron oxide; Texture; Porosity. Introduction Historically, oxide catalysts have been used primarily for vapor phase reaction in the petroleum and petrochemical industries. Recent work, however, has shown that these catalysts can also be effective in promoting a number of synthetically useful reactions. While simple oxides show activity for some oxidations, they are more commonly used as solid acids or bases. Complex oxides can act as acids or bases as well as oxidation catalysts. Complex oxide can range in composition from
