In this study. using a sensing membrane composed of p-type reduced graphene oxide (rGO)-decorated hydrothermally synthesized n-type gallium oxide (Ga2O3) nanorods. nitrogen dioxide (NO2) gas sensors were successfully fabricated. The characteristics of the rGO-decorated Ga2O3 nanorods were analyzed by X-ray photoelectron spectroscopy (XPS). https://toyscyclers.shop/product-category/bicycle-helmets/
