What is Degussa P25?
Degussa (Evonik) P25, Aeroxide TiO2 P 25, is a titania photocatalyst that is used widely because of its relatively high levels of activity in many photocatalytic reaction systems.
What is commercial P25?
The commercial catalyst P25 is the most used, and its crystalline composition contains about 78% anatase and 14% rutile, the remaining 8% corresponds to the amorphous phase [34] .
What is Anatase tio2?
Anatase (IMA symbol: Ant) is a metastable mineral form of titanium dioxide (TiO2). Anatase is always found as small, isolated and sharply developed crystals, and like the thermodynamically stable rutile (the more commonly occurring polymorph of titanium dioxide), it crystallizes in the tetragonal system.
What’s the difference between rutile TiO2 and anatase TiO2?
The key difference among them is in their appearance. Anatase Titanium Dioxide is colorless, whereas Rutile Titanium Dioxide is usually found in dark red appearance. Rutile titanium dioxide is optically positive, whereas Anatase titanium dioxide is optically negative.
What is anatase and rutile?
Titanium dioxide Tio2 has two forms: rutile and anatase. Rutile is deep red while anatase is yellow to blue. Rutile has a high absorbance property than anatase. Rutile and anatase are both used in the white pigmentation of paints, paper, and ceramics.
What is the difference between anatase and rutile?

What does P25 stand for?
Degussa (Evonik) P25, Aeroxide TiO 2 P 25, is a titania photocatalyst that is used widely because of its relatively high levels of activity in many photocatalytic reaction systems.
What is designdegussa?
Degussa is composed of anatase and rutile developing a wide range of environmentally crystallites and Degussa (Evonik) P25, Aeroxide beneficial products, including self-cleaning fabrics, TiO 2 P25, is a Titania photo catalyst that is auto body finishes, and ceramic tiles.
Is there an amorphous phase in P25?
The sample P25 was supplied by Nippon Aerosil in a scale of 1 kg. Anatase [6] and rutile [5] crystallites were isolated according to previous reports. It has been reported that P25 contains an amorphous phase based on transmission electron microscopy (TEM) [7], [8], but there have been no attempts to isolate the amorphous phase from P25.
