Abstract
Epitaxial Sr(V x Cr y Ti 1-x-y )O 3 (0≤x+y≤0.05) ternary composition spreads were grown on two different single crystal substrates, LaAlO 3 and Nb-doped SrTiO 3 , by use of combinatorial laser molecular beam epitaxy with a specially patterned slide masking plate. The photocatalytic activity on the composition spreads was evaluated by the photo-reduction of Ag + in an AgNO 3 aqueous solution to deposit Ag metal on the spreads. The V-doping effect was found to depend greatly on the substrate: the photodeposition of Ag was much enhanced in the composition region of SrV 0.05 Ti 0.95 O 3 only on the Nb-doped SrTiO 3 , but not on the LaAlO 3 and non-doped SrTiO 3 .
