title: Synthesis and charge storage properties of templated LaMnO3-SiO2composite materials.
abstract: Mesoporous LaMnO3with bulk surface areas in the range 225-300 m2g-1were prepared by direct overgrowth around the short-channel version of SBA-15 silica. The extent of LaMnO3growth was found to be affected by the polarity of solvent system used to impregnate the SBA-15 with La3+and Mn2+precursors. The resulting LaMnO3-SiO2composites were stable in refluxing NaOH, suggesting that the SiO2was fully encapsulated. The composites were structurally characterized using a range of techniques including 2-D elemental mapping and Raman spectroscopy. The electrochemical behavior of the composites was tested for pseudocapacitance, which revealed normalized specific capacitances over 200 F g-1.
