Abstract

TTB-type NaNbWO6 has been used to perform sodium-proton exchange reactions by using nitric acid as an exchanging agent. The characterisation of the exchange reaction products, performed by means of chemical analysis, X-ray diffraction and thermogravimetric analysis, indicate that the exchange reaction takes place topotactically. The following formula is proposed for the obtained phase of variable composition: Na1-xHxNbWO6 (0<x<0.46).
