Synthesis, characterisation and ethanol sensing applications of MoO3 – MoO2 nanostructures at room temperature

In the present work, MoO3 - MoO2 nanocomposite is synthesised via hydrothermal method and is characterised using various state-of-the-art techniques. The high crystallinity of the sample is observed from XRD and FESEM reveals the 2D plate like layered structures with hexagonal facets. The prepared c...

Description
Summary:In the present work, MoO3 - MoO2 nanocomposite is synthesised via hydrothermal method and is characterised using various state-of-the-art techniques. The high crystallinity of the sample is observed from XRD and FESEM reveals the 2D plate like layered structures with hexagonal facets. The prepared composite is subjected to ethanol sensing at room temperature and it is observed that the material exhibits 4.5% for 25 ppm ethanol with response time as 98 s and recovery time as 219 s. The observed small response of the composite material MoO3 – MoO2 with longer response-recovery time might be due to the large sized fibrils observed.
