“…So far, the development of TiO 2 coatings with improved photoactive and photoelectrochemical properties has primarily concentrated on the methods to synthesize the TiO 2 coating, [27,34,58] the optimization of the following heat treatments [32] or the doping of the coatings [56,59,60]. However, as mentioned above, also the selection of the substrate material plays a key role with respect to the properties of the coating.…”

Micron thick Titanium Dioxide (TiO 2 ) coatings exhibiting a nano-structured, anatase, mesoporous structure were successfully deposited across a range of polymer, conductive glass and metallic substrates at low velocities using a microblasting technique. This process was conducted at atmospheric pressure using compressed air as the carrier gas and commercially available agglomerated nano particles of TiO 2 as the feedstock. An examination of the effect of impact kinetics on the agglomerated powder before and after deposition was undertaken. A further examination of the coating microstructure along with photocurrent density measurements before and after thermal treatments was explored. Owing to the low temperature and velocity of the powder during deposition no change in phase of the powder or damage to the substrate was observed. The resulting TiO 2 coatings exhibited relatively good adhesion on both titanium and FTO coated glass substrates with coating thickness of approximately 1.5 μm. Photo-catalytic performance was measured under solar simulator illumination using a photo-electrochemical cell (PEC) with a 5 fold increase in performance observed after thermal treatment of the TiO 2 coated substrates. Microblasting was demonstrated to be a rapid and cost effective method for the deposition of nano-structured, photo-catalytic, anatase TiO 2 coatings.

“…However, in most of the study there was a high temperature effect on the spray feedstock, which may lead to the phase transformation from anatase to rutile ( . Although it was reported that the high-temperature flame can be avoided for TiO 2 coating deposition by conventional cold spray, it is much difficult to deposit thick coating with a thickness more than [10][11][12][13][14][15].…”

Composite powder was prepared using primary nanoTiO 2 powder and polyethylene glycol (PEG). The nanoTiO 2 coating was deposited through vacuum cold spray using both the composite powder and the primary nanopowder. The influence of annealing on the coating adhesion and photocatalytic activity was investigated. The coating adhesion was evaluated through erosion test by water jet. The photocatalytic performance of the coatings was evaluated through photodegradation of phenol in water. Results showed that annealing of the coating at a temperature from 450 to 500°C yielded both higher activity and better adhesion. The adhesion of the coating deposited using the composite powder was better than that using the primary nanoTiO 2 powder. It was found that the TiO 2 coating, resulting from the composite powder, presented much higher activity than that deposited with the primary nanopowder. The better activity is attributed to the existence of large pores resulting from the stacking of composite powder, which benefits the reactantsÕ transportation through the porous coating.
