Study on room temperature gas-sensing performance of CuO film-decorated ordered porous ZnO composite by In₂O₃ sensitization.

ABSTRACT: For the first time, ordered mesoporous ZnO nanoparticles have been synthesized by a template method. The electroplating after chemical plating method was creatively used to form copper film on the surface of the prepared ZnO, and then a CuO film-decorated ordered porous ZnO composite (CuO/ZnO) was obtained by a high-temperature oxidation method. In₂O₃ was loaded into the prepared CuO film-ZnO by an ultrasonic-assisted method to sensitize the room temperature gas-sensing performance of the prepared CuO/ZnO materials. The doped In₂O₃ could effectively improve the gas-sensing properties of the prepared materials to nitrogen oxides (NO _x ) at room temperature. The 1% In₂O₃ doped CuO/ZnO sample (1 wt% In_2</
