This hybrid structure consisted of CCHH and RGO (synthesized by a one-step hydrothermal method), in which RGO uniformly dispersed in CCHH, being used as the gas sensing film. The resistivity of the hybrid structure was highly sensitive to the changes on NH3 concentration. CCHH in the hybrid structure was the sensing material and RGO was the conductive channel material. The hybrid structure could improve signal-to-noise ratio (SNR) and the sensitivity by obtaining the optimal mass proportion of RGO, since the proportion of RGO was directly related to sensitivity. The gas sensor with 0.4 wt% RGO showed the highest gas sensing response reach to 9% to 1 ppm NH3. Compared to a conventional gas sensor, the proposed sensor not only showed high gas sensing response at room temperature but also was easy to achieve large-scale production due to the good stability and simple synthesis process.<\/jats:p>","DOI":"10.3390\/s19030615","type":"journal-article","created":{"date-parts":[[2019,2,1]],"date-time":"2019-02-01T16:19:58Z","timestamp":1549037998000},"page":"615","source":"Crossref","is-referenced-by-count":7,"title":["Simple Synthesis of Cobalt Carbonate Hydroxide Hydrate and Reduced Graphene Oxide Hybrid Structure for High-Performance Room Temperature NH3 Sensor"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1339-3259","authenticated-orcid":false,"given":"Chang","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Microelectronics, School of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"},{"name":"Guangdong Shunde Xi\u2019an Jiaotong University Academy, NO.3 Deshengdong Road, Daliang, Shunde District, Foshan 528300, China"}]},{"given":"Huan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Microelectronics, School of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Dan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Microelectronics, School of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]},{"given":"Xianqi","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Microelectronics, School of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"},{"name":"Research Institute of Xi\u2019an Jiaotong University, No. 328 Wenming Road, Xiaoshan District, Hangzhou 311215, China"}]},{"given":"Xin","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Microelectronics, School of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"},{"name":"Guangdong Shunde Xi\u2019an Jiaotong University Academy, NO.3 Deshengdong Road, Daliang, Shunde District, Foshan 528300, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5748-3021","authenticated-orcid":false,"given":"Weihua","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Microelectronics, School of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"},{"name":"Guangdong Shunde Xi\u2019an Jiaotong University Academy, NO.3 Deshengdong Road, Daliang, Shunde District, Foshan 528300, China"}]},{"given":"Hongzhong","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Manufacturing Systems Engineering, Xi\u2019an Jiaotong University, Xi\u2019an 710049, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1869","DOI":"10.1063\/1.1504867","article-title":"Stable and highly sensitive gas sensors based on semiconducting oxide nanobelts","volume":"81","author":"Comini","year":"2002","journal-title":"Appl.
