Co3O4 nanostructures and Co3O4 supported on halloysite nanotubes: New highly active and thermally stable feasible catalysts for CO oxidation
Source abstract
Abstract
Abstract Co3O4 nanostructures were successfully pre-synthesized and then, deposited on natural halloysite nanotubes (HNTs) surfaces. A typical porous Co3O4 network was initially obtained, consisting of tightly assembled and sintered nanocrystallites. Nevertheless, when halloysite was included, Co3O4 nanoparticles, with a narrow size distribution (4.6 ± 1.2 nm), were uniformly attached on the HNTs surface. Bare Co3O4 nanostructure and Co3O4-HNTs nanocomposite (10% w/w Co3O4), presented high catalytic activity in CO oxidation. Regarding the catalytic behavior, bare Co3O4 nanostructures reached complete conversions from 130 to 900 °C, while Co3O4-HNTs nanocomposite produced a CO oxidation efficiency of 97% between 350 and 900 °C. Besides, a cyclability analysis was achieved at 150 and 500 °C. None of the samples presented an important decrease in the catalytic activity, as the CO conversion efficiencies were maintained during all the cycles performed. Finally, a first approximation of catalyst stability in the presence of H2S was studied.
