The synthesis of Cu-doped TiO2 in a single-step flame aerosol process is reported in this paper.
An examination of the alumina produced by the aerosol process suggests a high-surface area form of α-alumina.
Initially, a typical aerosol process is considered and a detailed population balance model is presented which describes how the aerosol size distribution evolves with time.
Further analysis revealed that bimodality is intrinsic to an aerosol process involving particle-particle coagulation and particle nucleation dominated by monomer dimerization.
Especially, by taking advantage of the subtle interplay between the parameters controlling NPs formation in aerosol process, it is possible to obtain either a continuous, three-dimensional network of particles (present a matrix structure) or a hollow structure.
There exist various methods of producing titania nanoparticles, such as sol gel process, electrochemical coating, hydrothermal process, hydrolysis, microemulsion method, thermolysis, flame aerosol process, chemical vapor deposition, etc. [27, 28, 29, 30, 31, 32, 33, 34, 35].
The proposed nonlinear control method is successfully applied through simulations to a typical aerosol process and is shown to outperform a conventional proportional integral control scheme and deal effectively with disturbances in the feed to the process.
Well structured platinum nanoparticles were deposited on different metal oxide nanoparticles by continuous chemical vapor synthesis/metal organic chemical vapor deposition in an aerosol process and by fixed bed MOCVD at atmospheric pressure.
