摘要: Abstract The In 2 O 3 nanostructures with different morphologies including nanowires, nanobelts, nanotubes and nanoparticles have been prepared through a two-step route that involves nitridation re-oxidation treatment using commercial powders as the starting material. structural examinations reveal synthesized are polycrystals composed of large quantity smaller crystal sizes than electrochemical properties working electrodes Li-ion batteries investigated increase charge capacity has observed. present improved gas sensitivity compared raw Moreover, nanoparticle sensor exhibits excellent selectivity to NO .
