title: Preparation and characterization of electrospun La(1-x)Ce(x)CoO(δ): Application to catalytic oxidation of benzene.
abstract: An electrospinning with calcination process was employed for the synthesis of La1-xCexCoOδ (x=0, 0.2, 0.4, 0.6, 0.8, and 1.0) oxides. These catalysts were investigated in terms of total benzene oxidation, and characterized by means of XRD, BET, H2-TPR, SEM, XPS, and TEM techniques. The results show that the amount of Ce doping obviously affects the physicochemical and catalytic properties of La1-xCexCoOδ, and when x=1.0, CeCoOδ exhibits the best activity and highly thermal durability for catalytic oxidation of benzene. Additionally, it is demonstrated that the increased activity over perovskite phase dominated oxides is ascribed to a larger surface area while the activity enhancement over metal oxides mainly results from a higher valance of Co and better redox property.
