      abstract     = {Porous tin dioxide is an important low-cost semiconductor
                      applied in electronics, gas sensors, and biosensors. 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.},
