•ZnO thin film was prepared by spray pyrolysis technique.•The formation of spherical shaped nanoparticles was observed.•The active detection range of hydrogen peroxide was found to be 10–50 ppm.•The minimum detection limit of hydrogen peroxide vapour was found to be 10 ppm.•The response and recovery times for 50 ppm were 115 s and 130 s, respectively.
The nanostructured ZnO thin films were deposited using spray pyrolysis technique. Formation of polycrystalinity with hexagonal wurtzite structure was observed from the structural study. Highly dense spherical shaped nanoparticles with fine crystallites were observed from the surface morphological studies. The light induced hydrogen peroxide vapour sensing was done using chemi-resistive method and its effect on the sensing response was studied and reported.
