Pt nanoparticles residing in the pores of porous LaNiO3 nanocubes as high-efficiency electrocatalyst for direct methanol fuel cells

Author affiliations

Abstract

Pt-filled porous LaNiO3 cubes are prepared through a facile route. The characterizations reveal that large numbers of pores (9–10 nm) are distributed homogeneously in porous LaNiO3 cubes. The Pt nanoparticles residing in the pores of porous LaNiO3 cubes are about 5 nm in size. The investigation on the electrocatalytic activity reveals that electrocatalytic activity of the obtained Pt loaded porous LaNiO3 nanocubes exhibit a significantly improved electrochemical active surface area (EASA) and a remarkably enhanced electrocatalytic performance toward methanol oxidation. The results are significant for improving the efficiency of Pt-based catalysts for DMFCs as well as the applications of perovskite compounds.
