Highly Active Rutile TiO Nanocrystalline Photocatalysts.

The controllable synthesis of rutile TiO single crystal particles with the preferential orientation of {111} facets still remains a scientific and technological challenge. Here, we developed a facile route for fabrication of rutile TiO nanorod crystals (RTiONRs) having high ratios of oxidative {111} to reductive {110} surfaces. RTiONRs were synthesized using a peroxo-titanium complex (PTC) approach, which was controlled by changing the Ti/HO ratio.

Immobilization of horseradish peroxidase onto kaolin.

Kaolin showed as a very perspective carrier for the enzyme immobilization and it was used for the adsorption of horseradish peroxidase (HRP). The effects of the enzyme concentration and pH on the immobilization efficiency were studied in the reaction with pyrogallol and anthraquinone dye C.I.
