Abstract
WO3 coatings with tunable micro-nano hybrid structures were fabricated by liquid precursor flame spraying. The coatings consisting of the sole component of monoclinic WO3 show porous topographical morphology with grains of â¼20 nm and pores of â¼4-8 μm. Assessment of gas sensing performances of the coatings to ozone reveals their optimum operating temperature of 150 °C, and sensor response of 3.9 and 46.7 to ozone concentration of 0.5 ppm and 2.0 ppm respectively. The results shed light on construction of ceramic coatings with tunable hybrid structures by the precursor flame spray technical route for functional applications.
