The nitrogen monoxide (NO) gas sensing properties of the Zn1−xCuxO sensors were studied systematically. The sensors were proved to have acceptable responses towards 20 ppb NO gas. Zn0.90Cu0.10O exhibited improved sensing performance at operating temperature of 55 °C compared to other samples. To improve sensor selectivity, a molecular zeolite filter was coated on the Zn0.90Cu0.10O sensor. The gas sensing results showed that the selectivity of intergrown zeolite filter coated Zn0.90Cu0.10O sensor enhanced significantly compared to uncoated sensors. © 2017Elsevier B.V.2018Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/14507https://doi.org/10.1016/j.matlet.2017.10.1210167-577XenMaterials Lettersinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14507
