Surface Acidity and Properties of TiO2/SiO2 Catalysts Prepared by Atomic Layer Deposition: UV−visible Diffuse Reflectance, DRIFTS, and Visible Raman Spectroscopy Studies

Highly uniform submonolayer to multilayer thin films of titanium dioxide supported on high surface area silica gel have been synthesized by atomic layer deposition (ALD) using titanium tetrachloride (TiCl4) and titanium isopropoxide (TTIP) as metal precursors. The deposition rate of titania films from TiCl4 was found to be stable in the 150-300 °C temperature range, which is slightly higher tha...

Dioxide ( TiO 2 ) using Poly ( methyl methacrylate ) ( PMMA )

The Minnesota Nano Center’s Keller Hall facility includes an atomic layer deposition (ALD) machine that is capable of depositing uniform alumina (Al2O3), hafnium oxide (HfO2), silicon dioxide (SiO2), zinc oxide (ZnO), and titanium dioxide (TiO2). ALD works by building alternate layers on a film using two different precursor gases – one usually supplying the metallic atoms and water vapor (H2O) ...

Selective atomic layer deposition of titanium oxide on patterned self-assembled monolayers formed by microcontact printing.

We demonstrate a selective atomic layer deposition of TiO2 thin films on patterned alkylsiloxane self-assembled monolayers. Microcontact printing was done to prepare patterned monolayers of the alkylsiloxane on Si substrates. The patterned monolayers define and direct the selective deposition of the TiO2 thin film using atomic layer deposition. The selective atomic layer deposition is based on ...

Novel Antimicrobial Titanium Dioxide Nanotubes Obtained through a Combination of Atomic Layer Deposition and Electrospinning Technologies

The search for new antimicrobial substances has increased in recent years. Antimicrobial nanostructures are one of the most promising alternatives. In this work, titanium dioxide nanotubes were obtained by an atomic layer deposition (ALD) process over electrospun polyvinyl alcohol nanofibers (PVN) at different temperatures with the purpose of obtaining antimicrobial nanostructures with a high s...

اثر حضور نانوخوشه‌های مس به عنوان زیرلایه بر خواص بلوری و نوری لایه دی‌اکسیدتیتانیوم

Two 10 and 20nm samples of Cu nano-cluster were grown on quartz substrates with a thickness of by electron beam deposition method. Nanolayers of titanium dioxide with a thickness of 300 nm were deposited on these Cu nano-cluster layers. For comparison، a layer of titanium dioxide with a thickness of 300 nm was also coated on quartz substrate. All coatings were conducted using electron-beam phys...
