Manganese Oxide-Surface Modified Titanium(IV) Dioxide as Environmental Catalyst

The purpose of this study is to present an “environmental catalyst” possessing both thermocatalytic activity and visible-light activity for the decomposition of organic pollutants. Molecule-sized MnOx clusters are highly dispersed on the surface of TiO2 (anatase/rutile = 4/1 w/w, P-25, Degussa) by the chemisorption-calcination cycle technique using Mn(acac)3 complex as a precursor (MnOx/TiO2). ...

Graphite / Titanium Dioxide Composite

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

Achieving Stable Results with Titanium Dioxide

Titanium dioxide has been a favored high index material by some, but it appears to be less popular with others because of difficulties in obtaining a stable result. We discuss what we think is the root of the problem and how it may be rectified. The need to have negligible absorption places a lower limit on the background oxygen pressure and some constraints on temperature and deposition rate. ...
