Studies on photocatalytic activity of zinc ferrite catalysts synthesized by shock waves

The photocatalytic activity in the photodehydrogenation of H2S of zinc ferrites synthesized by shock wave loading is investigated and compared with that of zinc ferrites prepared by calcination. It is shown that photocatalytic activity of zinc ferrites prepared by shock wave treatment is much higher and that this activity increases with the increase of shock wave pressure. XRD, TEM, and electron diffraction methods were used to characterize the catalysts. Possible reasons for the enhancement of photocatalytic activity are discussed.
