Fabrication of Indium Oxide on Indium Foil through a Solvothermal Process

In₂O₃ nanoribbons were produced directly from In metal foils by using a solvothermal approach. Presence of the excess OH⁻¹ ions was crucial in the formation of the In₂O₃ nanoribbons, and increase in concentration of the OH⁻¹ ions caused an increase in the density and length of the nanoribbons. The crystal structure and morphology of the products were investigated through X‐ray diffraction and scanning electron microscopic studies. The growth mechanism of the In₂O₃ nanoribbons was quite similar to that of the high‐temperature‐based vapor‐solid (VS) process.
