求教：德固赛 Degussa P25 万分感谢~~！ Degussa P25 老板问我一个问题，Degussa P25 为什么叫【P25】让我找到答案后，给他发邮件，他急用~~ 我晕，，  查了好久，也还没弄明白，这个P25，到底具体代表什么含义呢？P是什么的缩写啊？来这里求救，望指点~！有文献或者其他资料说明，最好了~ 万分感谢~！！ 谢谢~！ |

以下阿报道说明P25的编号中25不代表锐钛矿的含量。 别无他意，证明此事而已。希望继续追求真相 http://www.ips17.com/abstract/248.asp 17th International Conference on Photochemical Conversion and Storage of Solar Energy 27 July – 1 August 2008 Sydney Convention and Exhibition Centre, Sydney, AustraliaHomeHostsProgramTimetableAbstractsTours/TravelDestinationSponsorsGeneral InformationCommitteesBookmark This SiteWhat is Degussa P25? Crystal Composition Analysis, Reconstruction from Isolated Pure Particles, and Photocatalytic Activity Test Prof Bunsho Ohtani, Catalysis Research Center, Hokkaido University, Japan Mr Ding Li, Graduate School of Environmental Science, Hokkaido University, Japan Mr Yasunobu Azuma, Graduate School of Environmental Science, Hokkaido University, Japan Professor Ryu Abe, Catalysis Research Center, Hokkaido University, Japan It is well known that Degussa P25, a very famous titania powder sample, is composed of anatase and rutile crystallites, but, as far as the authors know, there have been no reports on correct quantitative analyses for the crystal composition. Recently, the author's group succeeded in isolation of anatase crystalline phases from P25 [1]. Using this pure anatase as well as rutile [2], calibration curves (Figure) for the X-ray diffraction peaks were obtained to determine the ratio of anatase, rutile and amorphous phase to be 78 : 14 : 8. Reconstitution of P25 was performed by mixing isolated pure anatase and rutile particles with a commercial amorphous titania in the above-mentioned ratio. An XRD pattern, BET surface area and a diffuse reflection spectrum of the reconstituted sample were almost the same as those of the original sample. The reconstituted sample showed the photocatalytic activities, in four reaction systems, which are almost the same as those by the original sample, even when the sample suspension was preparing only by putting two powders into an aqueous solution. This suggests that there is negligible synergetic effect by the co-presence of anatase and rutile in P25. [1] Trans. Mater. Res. Soc. Jpn. 2007, 32, 401. [2] J. Phys. Chem.
