摘要：

Silver was deposited on TiO2 powders (Degussa P25) by the photodecomposition of two different silver salts, AgF and AgNO3. The photocatalytic activity of TiO2 powder samples was evaluated by the degradation of 1,4-dichlorobenzene (DCB). Photodecomposition of AgF on TiO2 gave higher photocatalytic activity than that of AgNO3. The optimum catalytic activity found by the deposition of Ag was comparable to that obtained from Au. It was also observed that the photocatalytic activity of Ag-loaded TiO2 films was greater than that obtained for pure TiO2 films. This result is consistent with the results obtained for Ag-deposited TiO2 powders. © 1993 Academic Press, Inc.
