Synthesis and catalytic application of nanofibrous La(0.9)A(0.1)MnO(3) (A = Ca, Cu, Ag) with macroscopic shapes
Fabrication of nanofibrous La(0.9)A(0.1)MnO(3) (A = Ca, Cu, Ag) perovskite-type oxides with macroscopic shapes can be successfully obtained by using CNFs as templates. Field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) analysis confirmed the template effect and formation of nanofibrous perovskite-type oxides on macroscopic silica fiber. It turned out that it is reliable to control the desired single-phase La(0.9)A(0.1)MnO(3) (A = Ca, Cu; Ag) perovskite-type oxides formation by tuning the corresponding metal ratio during preparation process. Furthermore, it showed that the as-prepared nanofibrous La(0.9)A(0.1)MnO(3) (A = Ca, Cu, Ag) perovskite-type oxides can greatly decrease the combustion temperature of nanosized carbon black particles, and follows the order of La0.9Ag0.1MnO3 > La0.9Cu0.1MnO3 > La0.9Ca0.1MnO3, indicating their high potential application prospects in diesel soot particles treatment.
