“…These NPs can either be formed inside the discharge or be injected into it. Introducing directly NPs makes possible to choose their size and shape, which allows a better control of the final nanocomposite properties . The feasibility of this approach at atmospheric pressure was demonstrated by Bardon et al who improved anti‐corrosion properties by incorporating aluminum‐cerium oxide NPs into a polymer matrix.…”

Atmospheric pressure Dielectric Barrier Discharge (AP‐DBD) was used to deposit homogeneous carbon‐TiO2 composites. Non‐intrusive Laser Light Scattering was employed to study the transport of the nanoparticles across the plasma. The characteristics of the coating were found to depend on the gas flow and on the spray chamber used for introducing the nanoparticles (cyclonic and Scott spray chambers). According to the SEM images, higher gas flows favor the formation of more homogeneous coatings both in terms of thickness and NPs‐aggregates distribution regardless of the spray chamber. The Scott spray chamber was shown to be more efficient for the deposition of uniform coatings even at low gas flows. It also yields the highest Ti concentration that reaches up to 18%. Furthermore, the light scattered by the nanoparticles was shown to be directly related to the coating thickness, hence to the density of nanoparticles in the plasma.

“…Generally, to obtain crystalline anatase TiO 2 , the temperature needs to be above 400 • C and below 700 • C. Or crystalline rutile TiO 2 would be formed. [17]. In our reaction system, the energy of charged particles and excited neutrals can be enhanced by increasing the discharge power.…”

Highly crystallized TiO 2 flower-like films with observable strong white photoluminescence are successfully deposited on the quartz glass substrates in one-step within an atmospheric non-thermal Ar/O 2 /TiCl 4 plasma system. It has shown that the properties and the structure of the synthesized films are influenced by plasma parameters such as discharge power and precursor supply rate etc. The deposited films with various plasma powers are evaluated by field-emission scanning electron microscope (FE-SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and photoluminescent spectrum (PL). It is clear that the flower-like crystalline in which the flower blades are connected among each other can be greatly constructed on the TiO 2 film in the earlier stage. The evaluation of XRD and HRTEM show that the film is pure anatase phase when the discharge power is 100 W and it transformed into the mixed phase of anatase and rutile when the discharge power is 120 W and in an extended time of 2 hours. The anatase TiO 2 flower-like film shows a strong white photoluminescence which could have potentially great applications in photocatalyst, in-situ cytokine effects, biocompatible fluorescence probes or biological imaging.

“…TTIP is the most commonly used titanium precursor, but others, like titanium tetrachloride (TiCl 4 ), can be used as well for the synthesis of nanocrystalline titania powders by passing them through an atmospheric plasma, without the need of an extra heat treatment. With this set up, it was possible to form the crystalline anatase structure without the use of extra heating, just the dielectric barrier discharge (DBD) electromagnetic field proved to be sufficient 65…”

A review of published works in the field of catalyst synthesis and treatment with the use of non‐equilibrium plasma techniques has been composed. Non‐equilibrium plasmas, also called low temperature plasmas, are known for their high reactivity (high electron temperature), while keeping the overall gas temperature low. Non‐equilibrium plasmas are often applied for dry surface modifications as an environment friendly alternative for solvent‐based techniques. In the field of heterogeneous catalysis, non‐equilibrium plasmas are most commonly used for the treatment of catalytically active surfaces. Such applications can result into highly dispersed catalysts with high activity and stability, such as photo‐catalytically active titanium dioxide films. Moreover, (non‐equilibrium) plasma‐assisted chemical vapor deposition can also be used for the synthesis of powder‐like materials used in heterogeneous catalysis for a wide range of applications, for example, ultrafine Fe2O3. The research field is still emerging, but already proves to be very promising, as will be shown in the review.
