Structural, electro-magnetic and catalytic characterisation of the LaMn1–xCuxO3–δ system

Abstract

The LaMn1xCuxO3delta; system has been investigated for the first time from the point of view of the structure in relation to different preparation procedures. Skeletal FTIR spectroscopy has been used in support to XRD characterisation. Oxygen content, magnetic behaviour and resistivity have also been measured. Two compositions have been tested in the catalytic combustion of methane.
