In this study, nitrogen-dopedncarbon quantum dots (N-CQDs) with high reactivity were used to activatendandelion-like hierarchical tungsten oxide (WO3) microspheresnto construct an efficient and stable acetone gas sensor. Benefitingnfrom the synergistic effect of both the abundant active sites providednby the unique dandelion-like hierarchical structure and the high reactionnpotential generated by the sensitization of the N-CQDs, the resultingn16 wt % N-CQDs/WO3 sensor shows an ultrahigh response valuen(Ra/Rg = 74@1nppm acetone), low detection limit (0.05 ppm), outstanding selectivity,nand reliable stability to acetone at the optimum working temperaturenof 210 °C. Noteworthy that the N-CQDs facilitate the carriernmigration and intensify the reaction between acetone and WO3 during the sensing process. Considering the above advantages, N-CQDsnas a sensitizer to achieve excellent gas-sensitive properties of WO3 are a promising new strategy for achieving accurate acetonendetection in real time and facilitating the development of portablenhuman-exhaled gas sensors.","PeriodicalId":523603,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147918877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
