Abstract

Zinc oxide (ZnO) nanostructures with different morphologies induced by variation of pH were successfully synthesized using the microwave-assisted hydrothermal method. Based on scanning electron microscopy (SEM), photoluminescence (PL) and electron paramagnetic resonance (EPR) studies, variation of pH have substantial effect on the morphology, surface defects, magnetic properties, and surface area of the ZnO nanostructures. The sensing performance of the ZnO nanostructures to different concentrations of methane (CH<sub>4</sub>), and ammonia (NH<sub>3</sub>) at 300&deg;C was investigated.
