2D bronze type tungsten oxide nano-sheet, light catalyst and photochromic element using methods and that it's manufacturing

摘要

PROBLEM TO BE SOLVED: To provide a tungsten oxide nanosheet having a 2D bronze structure that two or more of the 6-membered ring structures comprising a metal-oxygen octahedron are regularly arranged in a sheet cross-sectional direction, and also to provide a method for production thereof and a device using the same.;SOLUTION: The layered poly(tungstic acid) comprising a host layer having the 2D bronze structure is converted into a hydrogen ion exchanger having a solid acid property while maintaining its host structure, and a single layer peeling phenomenon is induced by introducing a bulky cation between the layers. Thereby, the tungsten oxide nanosheet is obtained, which has the 2D bronze structure that two or more of the 6-membered ring structures comprising a metal-oxygen octahedron are regularly arranged in a sheet cross-sectional direction.;COPYRIGHT: (C)2012,JPO&INPIT
