Abstract

Individual perovskite-like LaCoO3 obtained by the citrate method and LaCoO3 supported onto the mesoporous molecular sieve MSM-41 have been characterized by X-ray powder diffraction, EPMA, low-temperature nitrogen adsorption, H2 TPR, and EXAFS. The catalytic activity of the supported cobaltate in methanol oxidation is two orders of magnitude higher than the activity of the bulk cobaltate owing to nanosized LaCoO3 particles in the pores of the molecular sieve.
