We explore the low-temperature limit of atomic layer deposition of Pt using MeCpPtMe3 and O2. We reveal that by supplying a sufficiently high O2 exposure, highly dispersed and thermally stable Pt sub-nanometer clusters can be deposited onto the surface of P25 TiO2 nanoparticles e

The promotional effects on photocatalytic hydrogen production of CuxO clusters deposited using atomic layer deposition (ALD) on P25 TiO2 are presented. The structural and surface chemistry study of CuxO/TiO2 samples, along with first pr

The photocatalytic mechanism of TiO2 (P25) nanoparticles coated with SiO2 (SiO2:TiO2) by atomic layer deposition was investigated. The deposition of SiO2 on TiO2 not only gives a photocatalytic improvement for the

This work presents a gas-phase approach for the synthesis of Cu2O/TiO2 powder-based photocatalysts using atomic layer deposition (ALD). The process is carried out in a fluidized bed reactor working at atmospheric pressure using (trimethylvinylsilyl)-hexafluo

Photocatalysts for water purification typically lack efficiency for practical applications. Here we present a multi-component (Pt:SiO2:TiO2 (P25)) material that was designed using knowledge of reaction mechanisms of mono-modified catalysts (SiO2:T
...
We employed atomic layer deposition (ALD) to deposit ultrathin SiO2 layers on P25 TiO2 nanoparticles to fabricate TiO2/SiO2 core/shell nanostructures. The ALD process was carried out in a fluidized bed reactor working at atmospheric pre

This work presents a novel chemical vapor deposition (CVD) approach that enables the deposition of ultrathin and conformal SiO2 layers on TiO2 anatase nanoparticles at room temperature using SiCl4 and air containing water without the use of a cata
