Hydrogen bronzes, H_xV₂O₅, H_xNb₂O₅, H_xM_oO₃ and H_xWO₃, were synthesized by irradiating respective oxide powders, either with or without loading of Pt, suspended in 1 : 1 aqueous ethanol solution. All products had a different colour from the parent oxides, which fades out in a moist air. Photoacoustic spectra showed a broad and structureless absorption over the visible region. This method gives bronzes with a small x value (x ?? 0.02) except for H_0.32V₂0₅ and having the same X-ray diffraction pattern as that of the parent oxide.
