Description

The synthesis of the polyvanadomolybdate xerogels with the general formula (NH4)2-xHxV12-yMoyO31±δ·nH2O is accomplished in form of powders and films and their structure and certain properties are studied. It is shown, that the molybdenum additions by the peroxide method of synthesis of the polyvanadates with the H2V12O31-δ·nH2O quasi-unidimensional layered structure stabilize the gel formation process and increase the thermal stability of the given xerogels. The films of the obtained xerogels consists of the V-O-Mo layers, formed by the type of the δ-phase layers of the vanadium oxide bronze (NH4)0.5V2O5

Abstract (Russian)

Осуществлен синтез, изучено строение и некоторые свойства ксерогелей поливанадатов-молибдатов с общей формулой (NH4)2-xHxV12-yMoyO31±δ·nH2O в виде порошков и пленок. Показано, что добавки молибдена при пероксидном методе синтеза поливанадатов с квазиодномерной слоистой структурой H2V12O31-δ·nH2O стабилизируют процесс образования гелей и повышают термическую устойчивость данных ксерогелей. Пленки полученных ксерогелей состоят из слоев V-O-Mo, построенных по типу слоев δ-фазы оксидной ванадиевой бронзы (NH4)0.5V2O5
