Ink-jet printing of a TiO2–10%ZrO2 thin film for oxygen detection using a solution of metal alkoxoacetylacetonates

Abstract A solution of metal alkoxoacetylacetonates in isoamyl alcohol was used as a functional ink for ink-jet printing of TiO2–10%ZrO2 thin nanostructured films. It is shown that the anatase crystal lattice is formed during heat treatment of xerogel thin films in air at a temperature of 500 °C. According to the scanning electron microscopy, the particle size of the resulting films was 10–11 nm. The effect of the number of TiO2-ZrO2 deposited layers on resulting 2D-nanomaterial sensitivity to oxygen and other analyte gases (H2, CH4 and CO) at temperatures of 400 and 450 °C is shown.
