Rutile and anatase mixed TiO2 is a promising material for photocatalytic applications. In this work, rutile-anatase core-shell nanotube (NT) and nanorod (NR) structures were fabricated directly on a fluorine doped SnO2 (FTO) glass substrate using a hydrothermal growing/etching and TiCl4 post-treat...
TiO2 powder (P-25), widely used as the support for metal catalysts, contains both anatase and rutile TiO2 phases. It is important to distinguish these two crystalline phases at the nanoscale in order to understand the effect of the support structure in Au/TiO2 catalysis. In this study, the...
A convincing explanation of why mixed phases of anatase and rutile TiO2 outperform individual polymorphs is lacking. An energetic band alignment of ~0.4 eV is now shown to exist between the two phases with anatase possessing the higher electron affini

求助：anatase tio2 和 rutile ti2的带隙值分别为多少？其CB和VB的位置分别在多少ev？
TiO2is the most widely used material for the electron transport layers (ETLs) because it is characterized by proper band alignment with light absorbers, adequate optical transmittance, and high electron mobility. There are two thermodynamically stable crystal phases of TiO2: anatase and rutile. Howeve...
