The other common cocatalysts, such as Pt, Rh, RhxCryO3, and PtxCryO3
(4–6), were much less effective on GBVO0.10. Phases II–IV present
repeated runs of the same catalysts to show the stability of GBVO0.10.
In phase V, heat treatment (623 K in air for 1 h)
further intensified the photocatalytic activity of RuO2-cocatalyzed
GBVO0.10
