Kronos Titanium Dioxide Rutile Crystal 128

Kronos Titanium Dioxide Rutile Crystal 128

In general, scholars studied comparison of photocatalyst and carcinogen characteristics, and production methods between anatase and rutile forms of titanium dioxide nanoparticles. First of all, there is a band gap difference, and anatase has about 3.2 eV band gap, and rutile has about 3.0 eV band gap. Since absorption is inversely proportional to band gap, rutile can absorb more light than anatase. According to photoconductivity measurements, electron-hole pair life time is in anatase is longer than one in rutile, so more charge carriers in anatase participate in surface reactions. In addition, there are researches about toxicology of anatase and rutile titanium dioxide nanoparticles in particular subjects. Results show that anatase is more toxic than rutile. These are the fundamental comparisons, but there are also difference in usage and applications which are both rutile and anatase forms are used.
