Abstract

We report for the first time the growth of single-crystalline ternary mixed metal oxide nanowires consisting of Ir, Ru, V, and O via a vapour phase transport process by carefully controlling the relative ratios of IrO₂, RuO₂, and VO₂ precursors, which have a tetragonal rutile crystal structure with similar lattice parameters. We clearly observed that various compositions of Ir_1-x-yRu_xV_yO₂ nanowires were readily modulated by randomly incorporating Ir⁴⁺, Ru⁴⁺, and V⁴⁺ metal ions into the tetragonal lattice unit owing to their similar ionic sizes as confirmed by STEM elementary mapping as well as X-ray diffraction patterns for analysis of the crystal structure of mixed metal oxide nanowires.
