“…Both catalysts were prepared by the impregnation procedure following calcination at 723 K. Redolfi et al reported the phase diagram of the Ni–Mn–O system. In this result, there is a mixture of NiO and Ni 6 MnO 8 phases above a Ni/(Ni + Mn) ratio of 0.85 in the Ni–Mn–O system . However, the XRD result of 9Ni–1Mn/SBA-15 shows only the NiO phase, and its crystallite size is about 5 nm.…”

The reaction mechanism of steam reforming of cyclohexane as a model compound of tar on Ni/SBA-15 and Ni−Mn/ SBA-15 catalysts was investigated by the transient technique and temperature-programmed reduction method. These catalysts were prepared by the impregnation of SBA-15 with an ethylene glycol-containing metal precursor and characterized by transmission electron microscopy (TEM), X-ray diffraction, and X-ray photoelectron spectroscopy. The spent catalysts were characterized by thermogravimetric analysis and Raman spectrometry. According to TEM analysis, it was considered that the Ni−Mn alloy state was formed on 9Ni−1Mn/SBA-15. Compared with the 10Ni/SBA-15 catalyst, the addition of Mn into Ni increased the formation of H 2 because of strong interactions between Ni and Mn in the Ni−Mn alloy and acceleration of the dehydrogenation of C 6 H 12 .
