Abstract

Mesoporous modified-red-mud (MRM) was obtained via the modification of as-received red mud (RM) by the acid digestion and alkali reprecipitation approach, which was further employed as the support for preparation of Ni/MRM catalysts by the impregnation method. The textural and structural properties of the MRM and as-prepared Ni/MRM catalysts were fully characterized by X-ray diffraction (XRD), thermogravimetry-differential thermal gravity analysis (TG-DTG), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and Fourier transform infrared spectra (FT-IR) techniques. The catalytic behavior of the prepared Ni/MRM catalysts for ammonia decomposition was investigated, indicating excellent catalytic activity, comparable to the previously reported metal oxide supported Ni catalysts. This study demonstrates the feasibility of utilizing the waste from the aluminum industry for the decomposition of ammonia to hydrogen.

Abstract

Mesoporous CoFe 2 O 4 nanomaterials were successfully synthesized via the cetyltrimethylammonium bromide (CTAB)-assisted method at normal pressure. The structure and morphology of the as-prepared CoFe 2 O 4 samples were characterized by XRD, TG-DTA, FT-IR, TEM and N 2 -sorption analysis. XRD studies indicated that the as-prepared product was well-crystallized spinel cobalt ferrite. The TEM image showed that the obtained CoFe 2 O 4 sample consisted of nanoparticles with the size about 15 nm. N 2 -sorption analysis indicated that the mesoporous CoFe 2 O 4 possesses a wormhole-like mesoporous structure with a narrow pore size distribution and high surface area (94.3 m 2 /g). The catalytic property of the as-prepared CoFe 2 O 4 for low-temperature CO oxidation was evaluated by using a microreactor-GC system, and the result shows that it is very active for CO total oxidation at 140 °C.
