Here, we present a versatile template-assisted synthesis of nanostructured tin dioxide thin films using cellulose nanocrystals (CNCs). We demonstrate that the structural features of CNC-templated tin dioxide films strongly depend on the precursor composition. The precursor properties were studied by using low-temperature nuclear magnetic resonance spectroscopy of tin tetrachloride in solution. We demonstrate that it is possible to optimize the precursor conditions to obtain homogeneous precursor mixtures and therefore highly porous thin films with pore dimensions in the range of 10–20 nm (ABET = 46–64 m2 g–1, measured on powder). Finally, by exploiting the high surface area of the material, we developed a resistive gas sensor based on CNC-templated tin dioxide. The sensor shows high sensitivity to carbon monoxide (CO) in ppm concentrations and low cross-sensitivity to humidity. Most importantly, the sensing kinetics are remarkably fast; both the response to the analyte gas and the signal decay after gas exposure occur within a few seconds, faster than in standard SnO2-based CO sensors. This is attributed to the high gas accessibility of the very thin porous film."}],"publication_status":"published","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"publication_identifier":{"issn":["1944-8244","1944-8252"]},"author":[{"first_name":"Alesja","full_name":"Ivanova, Alesja","last_name":"Ivanova"},{"first_name":"Bruno","full_name":"Frka-Petesic, Bruno","last_name":"Frka-Petesic"},{"first_name":"Andrej","last_name":"Paul","full_name":"Paul, Andrej"},{"first_name":"Thorsten","last_name":"Wagner","full_name":"Wagner, Thorsten"},{"first_name":"Askhat N.","last_name":"Jumabekov","full_name":"Jumabekov, Askhat N."},{"first_name":"Yury","last_name":"Vilk","full_name":"Vilk, Yury"},{"last_name":"Weber","full_name":"Weber, Johannes","first_name":"Johannes"},{"full_name":"Schmedt auf der Günne, Jörn","last_name":"Schmedt auf der Günne","first_name":"Jörn"},{"full_name":"Vignolini, Silvia","last_name":"Vignolini","first_name":"Silvia"},{"id":"23547","first_name":"Michael","full_name":"Tiemann, Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722"},{"first_name":"Dina","full_name":"Fattakhova-Rohlfing, Dina","last_name":"Fattakhova-Rohlfing"},{"first_name":"Thomas","last_name":"Bein","full_name":"Bein, Thomas"}],"year":"2020","user_id":"23547","citation":{"bibtex":"@article{Ivanova_Frka-Petesic_Paul_Wagner_Jumabekov_Vilk_Weber_Schmedt auf der Günne_Vignolini_Tiemann_et al._2020, title={Cellulose Nanocrystal-Templated Tin Dioxide Thin Films for Gas Sensing}, DOI={<a href=\"https://doi.org/10.1021/acsami.9b11891\">10.1021/acsami.9b11891</a>}, journal={ACS Applied Materials &#38; Interfaces}, author={Ivanova, Alesja and Frka-Petesic, Bruno and Paul, Andrej and Wagner, Thorsten and Jumabekov, Askhat N. and Vilk, Yury and Weber, Johannes and Schmedt auf der Günne, Jörn and Vignolini, Silvia and Tiemann, Michael and et al.}, year={2020}, pages={12639–12647} }","mla":"Ivanova, Alesja, et al. “Cellulose Nanocrystal-Templated Tin Dioxide Thin Films for Gas Sensing.” <i>ACS Applied Materials &#38; Interfaces</i>, 2020, pp. 12639–47, doi:<a href=\"https://doi.org/10.1021/acsami.9b11891\">10.1021/acsami.9b11891</a>.","ieee":"A.
