Abstract: Porous ZnO nanostructures were synthesized using a microwave-assisted hydrothermal method, followed by calcination to induce pore formation by removing the urea used during synthesis. After microwave synthesis, field-emission scanning electron microscopy (FESEM) images confirmed the formation of ZnO flowers and plates, with pores generated in the flower petals and plates following calcination. The porous ZnO sensor demonstrated the ability to detect low concentrations of O3 and exhibited relatively low response and recovery times. Additionally, the porous ZnO sensor was exposed to four gases (O3, NO2, NH3, and CO), showing a high selectivity for O3.
