Abstract We have developed a facile low-cost approach to the fabrication of large-scale flower-like perovskite-type oxides: orthorhombic LaCr 0.9Ni0.1O3-δ nanowires. The nanowires (∼76.2%) exhibited higher CO2 conversion than their conventional bulk counterpart (∼40.1%) due to exposure of more active sites. The unique morphological structure of the nanowires enhanced the dispersion of Pd nanoparticles on its edges and surfaces, resulting in excellent performance and stability in CO2 reforming of methane. The Pd decorated LaCr 0.9Ni0.1O3-δ nanowires exhibit optimum CO2 and CH4 conversions of ∼98.6% and ∼75.4% at 800 °C. The high turnover frequency (TOF) of CH4 (6.04 s -1) on 1 wt% Pd decorated LaCr0.9Ni0.1O 3-δ might be attributed to high dispersion of Pd species on the nanowires. This journal is
