Abstract:
Photodeposition of Pt on the Sc-doped La5Ti2CuS5O7 (Sc-LTC) photocathode, a visible-light-responsive semiconducting oxysulfide, is accomplished in a solution containing H2PtCl6 and K2C2O4. Pt particles are selectively deposited on the top surface of rod-like Sc-LTC particles as a result of one-dimensional transfer of photogenerated electrons.
