The visible-light photocatalytic efficiency of BiOCl/Bi 2 O 3 composites was notably enhanced by covering their surfaces with monolayer of WO 3 . The photocatalytic activity of WO 3 /BiOCl/Bi 2 O 3 in decomposing gaseous 2-propanol (IP) and aqueous 1

Highly crystallized TiO2(B) in a flat-whiskered morphology, with a width of ∼300 nm, thickness of 50–100 nm, and length of several microns, was successfully synthesized by three-step reactions employing Degussa P25 and CsCO3 as starting materials

For the first time we report novel BiOCl/Bi2O3 photocatalyst functional under visible light irradiation. Even though both the individual BiOCl and Bi2O3 show very low photocatalytic efficiency under visible light irradiation, their heterojunctions pr

We present a study of the photoresist (PR) etching and the low-k materials damage using a ferrite-core inductively coupled plasma (ICP) etcher, in order to develop an etching process for the low-k dielectric devices. We reveal that the N2/O2 flow rat

A new process for controlling the structure of TiO2 from hollow microspheres to highly dispersible nanoparticles has been developed by altering the concentration of tetrabutylammonium hydroxide (TBAH) in the solvothermal reaction of titanium isopropo

Highly organized and crystallized cubic and hexagonal mesoporous SnO2 thin films were selectively synthesized via an evaporation-induced self-assembly (EISA) process with SnCl4 as the precursor and a triblock copolymer (pluronic F127) as the template

Monodispersed 2.4 nm-sized SnO2 and 2.6 nm-sized CeO2 nanoparticles have been reproducibly formed through a non-hydrolytic solvothermal reaction with 2-ethylhexanoate complexes, without the addition of extra surfactants. During the synthesis, the dis

WO3/TiO2 was prepared by modifying the surface of TiO2 with clusters of crystallized WO3. Previously, we have reported that the TiO2 covered with the monolayer of WO3 shows greatly enhanced photocatalytic activity under UV light in decomposing VOCs.

2.5 nm-sized SnO2 nanoparticles in rutile phase were loaded on the surface of 25 nm-sized TiO2 (Degussa P-25) to form SnO2/TiO2 nano-composite structure. Up to 10 mol%, the loaded SnO2 nanoparticles were well-dispersed on the surface of TiO2 without
