英文摘要	In this paper, a series of hollow In2O3 @ Pd-Co3O4 core/shell nanofibers with ultra-thin shell about 20–30 nm have been successfully fabricated by coaxial electrospinning, which used in CO oxidation. Desirably, the In2O3 @ Pd-Co3O4 exhibited the higher CO activity with T90 = 56 °C and lower activation energy. Through some characterizations, it is verified that ultra-thin shell structures, stronger redox ability, structure defects, higher proportion of Pd2+ species and smaller proportion of Co3+ species and higher chemical adsorbed oxygen species of In2O3 @ Pd-Co3O4 were preponderant to the increase of CO activity. Therefore, the In2O3 @ Pd-Co3O4 catalyst could be considered a prospective candidate for the CO oxidation. © 2019 Elsevier B.V.
