| Abstract |
An ethanol steam reforming (ESR) reaction is a H2-production process that the fuel reacts with water in the
presence of catalysts. The catalyst structures and active phase compositions have a role in ethanol conversion and
hydrogen-production selectivity. The Fe3O4 catalysts with Ni and Cr dopants were prepared and used for the ESR.
The morphology and structural property of prepared catalysts were determined by FESEM-EDS, XRD, and XAS
techniques. The spinel structures were observed in Fe3O4, Ni/Cr@Fe3O4, and NiFe2O4 while the CrFe2O4
exhibited a mixture between Fe2O3 and Cr2O3 phases. The combined X-ray absorption spectroscopy, mass
spectrometry, and gas chromatography was applied to investigate the performance of prepared catalysts during
temperature-programmed reduction and ESR processes. The NiFe2O4 exhibited the highest catalytic activity and
stability for hydrogen production. The Ni-incorporation in spinel ferrite structure enhanced reduction efficiency
of iron compounds at low temperatures and improves its catalytic activity and stability to the ESR process.
Furthermore, the NiFe2O4 catalyst also exhibited the ability to regenerate during ESR process as evidenced by Xray absorption spectrum |
