The nanocrystalline films and powders of tungstic acids WO3?nH2O with n???1 and 2 are obtained from sodium tungstate aqueous solution. The nanoscale structure, electrochemical, optical, and chemichromic properties of these films are stud-ied. A design of optical hydrogen sensor is developed, and its laboratory specimen is made on the base of these films with high hydrogen sensitivity in the range of low hydrogen concen-tration in the hydrogen–air mixture (down to under 0.01 vol.% [H2]).
