Title:
TRANSITION METAL COMPOUND-LOADED TITANIUM OXIDE SUSPENSION
Document Type and Number:
WIPO Patent Application WO/2014/045903
Kind Code:
A1
Abstract:
Provided is a transition metal compound-loaded titanium oxide suspension that includes transition metal compound-loaded titanium oxide crystals, has an extremely low content of ionic impurities, has excellent responsivity to visible light, and offers excellent photocatalytic capability. This transition metal compound-loaded titanium oxide suspension is a suspension of a transition metal compound-loaded titanium oxide in which a transition metal compound is loaded on crystalline titanium oxide, the transition metal compound-loaded titanium oxide having an average aspect ratio (major axis/minor axis) of 1.5 or greater. The suspension is characterized in that, if the content of the transition metal compound-loaded titanium oxide is 4 wt% or greater, the electric conductivity of the supernatant of the suspension is 300 µS/cm or less. Preferably, the crystalline titanium oxide is a rutile-type titanium oxide having crystal faces (110) and (111) and/or a rutile-type titanium oxide having crystal faces (110), (111), and (001).
