The efficiency of the photocatalysts MoS2, ZnTe or CdSe for the reduction of aqueous carbonate or Cr(VI) is compared with that of the usual catalyst Pt/anatase P25. The anatase pigment P25 [1], when photoplatinised [2], was found to be an efficient photocatalyst for the reduction of aqueous carbona
The electrokinetic behavior of titanium dioxide particles (Degussa P25, mainly composed of anatase) put in contact with chromium(VI) aqueous solutions is highly sensitive to light exposure under normal laboratory conditions. In the dark, adsorption of Cr(VI) gives rise to substantial decrements in t
