“…10,11 The mesoporous TiO 2 matrix is fabricated thanks to sol-gel and EISA methods 12 before incorporating silver ions. Few research studies considering inkjet [16][17][18][19] or exography [20][21][22] to deposit sol gel recently began to appear in electronics, [17][18][19][20]22 photovoltaics 21 and photocatalysis 16 areas. This heterogeneity leads to an inhomogeneous broadening of the localized plasmon resonance (LSPR) of Ag NPs and gives the lms a grey brown color.…”

“…This heterogeneity leads to an inhomogeneous broadening of the localized plasmon resonance (LSPR) of Ag NPs and gives the lms a grey brown color. Inkjet was rst chosen because it permits directly 16,17,19 to print patterns or continuous layers 18 with precision by controlling the amount of released ink. This oxidation results from the excitation of free electrons at the surface of particles, through their LSPR, and from their transfer to the TiO 2 conduction band.…”

“…For the sake of completeness, it should be mentioned that the films with such a response typically originate in sol-gel processes combined with molecular templating. Reverse micelles are ideally suited for such purposes [37][38][39][40][41][42][43], and the piezoelectric inkjet printing, for their surface deposition on conductive substrates. Of course, a tedious optimization of all steps is always compulsory.…”

The reaction rate concepts in heterogeneous catalysis are based on well-defined and usually well-quantified active sites. Such an active site is stable over time and its main features are typically constant. In heterogeneous photocatalysis, the active site is of different nature. Its existence depends on the instantaneous availability of photons and the variable ability of the photocatalyst to use them. In fact, a realistic expression of the active site that at least in the main feature -stability over timeresembles the classical heterogeneous catalytic concept is missing. Here, the concept of a dynamic active site of the heterogeneous oxidation photocatalyst that is (in a dynamic sense) time stable is elaborated and carefully discussed. The novelty of this approach should be seen in the straightforward applicability of standard kinetic models.

“…The authors of this paper have previously reported the deposition of sols based on reverse micelle templates [17] by inkjet printing. The resulting titania patterns showed interesting sensing properties [18] as well as photocatalytic activity [19] and the material inkjet printing approach was found extremely useful due to its precision, repeatability, inherent patterning capability and efficiency of material consumption.…”

Thin layers of titanium dioxide were fabricated by direct inkjet patterning of a reverse micelles sol-gel composition onto soda-lime glass plates. Several series of variable thickness samples were produced by repeated overprinting and these were further calcined at different temperatures. The resulting layers were inspected by optical and scanning electronic microscopy and their optical properties were investigated by spectroscopic ellipsometry in the range of 200-1000 nm. Thus the influence of the calcination temperature on material as well as optical properties of the patterned micellar titania was studied. The additive nature of the deposition process was demonstrated by a linear dependence of total thickness on the number of printed layers without being significantly affected by the calcination temperature. The micellar imprints structure of the titania layer resulted into significant deviation of measured optical constants from the values reported for bulk titania. The introduction of a void layer into the ellipsometric model was found necessary for this particular type of titania and enabled correct ellipsometric determination of layer thickness, well matching the thickness values from mechanical profilometry.
