Colloidal TiO2 sols which contain stable particles that are ca. 50 A in diameter have been produced. Scanning electron photomicrographs indicate that supported membranes which...
Supported γ-Al2O3 and TiO2 ceramic membranes were prepared by sol-gel techniques from alkoxide precursors. Tests were conducted to measure the permeabilities of these membranes to...
This paper discusses the physical-chemical properties of γ-Al2O3 and TiO2 ceramic membranes which have been prepared by sol-gel techniques from alkoxide starting materials. Mean pore...
Solar energy has been growing at an exponential rate over the past decade, and worldwide installed solar electric capacity is expected to more than double...
In this study, nanoporous zirconia (ZrO2) and titania (TiO2) coatings are shown to stabilize the cycling performance of lithium-ion batteries with LiMn2O4 spinel cathodes. The effect...
Nanoporous oxides (SiO2, TiO2, ZrO2, and AlOOH) synthesized from sol–gel chemistry techniques were used as coatings for stainless steel electrodes in water electrolysis systems. These...
Titanium-supported titania-based photoelectrodes were prepared either by sol-gel processes or by thermal oxidation. Catalytic activities and stabilities of these photoelectrodes were monitored by photooxidizing formic...
A photoelectrocatalytic reactor containing titania-coated titanium electrodes was employed to degrade solutions of formic acid (2 mmol dm-3) in 0.01 mol dm-3 NaCl. Reaction rates...
Photocatalysis is the use of light to activate a catalytic material. This technology is of interest because laboratory studies indicate that photocatalysis can completely oxidize...
The effect of reaction temperature on the catalytic and photocatalytic oxidation of ethylene on unplatinized and platinized versions of a TiO2/ZrO2 mixed-oxide thin-film catalyst is...
