  • The metal oxide catalyst TiO2 has been treated by shock wave, and then used as a photocatalyst for the dehydrogenation of H2S. Results show that, compared with the unshocked sample, the treated ones exhibit much higher photocatalytic activity within the experimental pressure range of 16~34 GPa, the activity has been increased by a factor of 2~3. Analyses of XRD and u.v. vis diffuse reflection spectra suggest that the enhancement may be attributed to the higher density of residual strain and dislocation defects and the degradation of energy gap of the shock treated TiO2.
