Abstract.
Fig. 3 FT-IR Spectrum of Cu-Fe-La/FSC Finding the inorganic spectrum gallery of FT-IR spectra gallery, 3460.30cm-1 and 1639.49cm-1 peak belonged to -OH-peak, and this caused by bending vibrations in the catalyst among the –H-O-H- bonds of water molecules, showing that there was also the presence of the structure water molecules after the catalyst roasts; In 675.09 cm-1 the -Al-O-bond belonged to the stretching vibration, which is a main component of catalyst body FSC.
