Fabrication of TiO2/Au nanorod arrays employing a positive sacrificial ZnO template and their electrochromic property

Removal of aqueous toxic Hg(II) by synthesized TiO2 nanoparticles and TiO2/montmorillonite

“…This lower temperature could explain the high surface area of the catalysts. The hydrolysis/polycondensation model for the formation of titanium dioxide from the reaction of titanium alkoxides with water in solution phase was 10 shown in some studies [22,[43][44][45]. The enhancement effect of solution pH value in the overall hydrolysis reaction is quite straightforward.…”

“…The enhancement effect of solution pH value in the overall hydrolysis reaction is quite straightforward. The dehydroxylation and the dealcoholation are accelerated to increase the overall surface hydrolysis process by acid [45]. During this acid catalyzed sol-gel process, both the formation of sol particles and the gelation process took place, which increased the local pH, resulting in the hydrolyzation of the Ti precursor, and created a dispersion of colloidal particles [22,[43][44][45]:…”

“…Further reaction caused bonds to form between sol particles, resulting in a network of titanium oxyhydroxide gel [45]:…”

Annealing temperature dependence on the structural and optical properties of sputtering-grown high-k HfO2 gate dielectrics

“…Solution-based methods mainly include sol-gel, metal-organic decomposition, and so on [17][18][19]. Compared to the solution deposition and chemical vapor deposition, the advantages of PVD-based deposition method included easily controllable growth of the low-k interfacial layer at low temperature and compositional consistency between the target and the deposited film [20][21][22]. However, the RF sputtering is one of the most feasible methods in fabricating high-quality thin films with inherent versatility and the capability of obtaining a homogeneous surface coverage at low temperatures under controlled processing conditions.…”

Investigation on preparation and photocatalytic activity of TiO2 nanosheet film on Ti substrate

“…Among different nanostructures, nanowires [3], nanotubes [4], nanobelts [5], nanoflakes [6], nanospheres [7] and nanorods [8] are some commonly reported architectures. In recent years, TiO 2 nanoarrays have been produced by a variety of methods, including template syntheses [9], anodic oxidization [10], metal-organic chemical vapor deposition [11] and hydrothermal synthesis [12].…”
