Abstract

The high-value-added chemical reagent peroxydisulfate (S₂O₈²⁻) was produced photocatalytically over noble-metal loaded WO₃ powder suspensions in aqueous H₂SO₄ under flowing O₂ and simulated solar light irradiation. Pt cocatalyst showed the highest photocatalytic activity for S₂O₈²⁻ formation of the studied metals (Au, Pd, Rh, and Ru). Further study indicated that continuous accumulation of S₂O₈²⁻ was achieved only over the Pt/WO₃ photocatalyst.
