Evonik Aeroxide P25 (formerly Degussa P25) is a flame-made multiphasic TiO2 nanoparticles containing anatase and rutile, as well as a small amount of amorphous TiO2. The past decades have witnessed the wide applications of P25 as a benchmark material for studying photocatalytic mechanism, materials and process. However, controversy remains regarding the microstructure of anatase and rutile: do they...
The formation of hydrous TiO2 (or TiO2 hydrates) by forced hydrolysis is a well-known sol–gel reaction. Self-assembly of nanosized primary TiO2 hydrates to monodisperse spheres has attracted numerous research interests for various applications. Recently the resultant hydrous TiO2 spheres (HTSs) have been demonstrated to be a versatile starting material for the facile and controllable synthesis of...
