Abstract

The catalytic decomposition of methane into hydrogen and carbon was studied on La 2 O 3 -promoted Raney-type Fe catalysts. Promoted catalysts were synthesized by in situ thermal treatment of physical mixtures of Raney Fe and La 2 O 3 . The catalysts were characterized by particle size measurement, Brunauer-Emmett-Teller method (BET), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). La 2 O 3 acts as a textural promoter. XPS reveals charge transfer from La 2 O 3 to Fe. Promoted Raney Fe catalyst with an optimum loading of La 2 O 3 exhibited good performance in methane decomposition.
