The Fe<sub>2</sub>O<sub>3</sub>/Carbon hybrid nanoparticles (NPs) were fabricated by using dual-nozzle electrospray, heat stirring and carbonization. According to the increased diameter of polypyrrole (PPy) NPs as core parts, the size of hybrid NPs also increased gradually. Furthermore, the Brunauer-Emmett-Teller (BET) surface area was decreased, exponentially. This is because the additional pore in carbonization steps. These synthesized hybrid NPs were applied to detect the NO<sub>2</sub> gas at room temperature. The minimum detectable level (MDL) of hybrid NPs was as low as 1 ppm, which is higher than that for a chemical sensor based on hybrid materials.
