- W2004199471 abstract "The modification of the surface reception properties of nanocrystalline structures is of great interest in environmental, catalysis and energy related applications. For instance, an oxide surface covered with a layer of another oxide opens the possibility of creating the nanosized counterparts of bulk catalytic systems. A relevant example is the TiO<sub>2</sub>-WO<sub>3</sub>, which is an active catalysts in a broad range of reactions. The chemical synthesis of the colloidal, nanocrystalline version of such system will first be exposed, by coupling suitable sol-gel chemistry with solvothermal processing. Then, the range of obtained structures will be discussed, ranging from WO<sub>x</sub>-surface modified TiO<sub>2</sub> to TiO<sub>2</sub>-WO<sub>3</sub> heterojunctions. The complex structural evolution of the materials will be discussed, depending on the W concentration. A summary of the acetone sensing properties of these systems will be shown. In particular, the surface activation of the otherwise almost inactive pure TiO<sub>2</sub> by surface deposition of WO<sub>3</sub>-like layers will be highlighted. Addition of the smallest W concentration boosted the sensor response to values comparable to those of pure WO<sub>3</sub>, ranging over 2-3 orders of magnitude of conductance variation in presence of ethanol or acetone gases. Simple analysis of the sensing data will evidence that the combination of such nanocrystalline oxides results in catalytic activation effects, with exactly opposite trend, with respect to pure TiO<sub>2</sub>, of the activation energies and best responses." @default.
