Synergetic effect of dual co-catalysts on the activity of BiVO₄ for photocatalytic carbamazepine degradation.

ABSTRACT: An efficient visible-light driven three components photocatalyst for carbamazepine (CBZ) degradation has been assembled by co-loading reduction cocatalyst Pt and oxidation cocatalyst Co₃O₄ (MnO _x ) on BiVO₄. The apparent rate constant of the three components photocatalyst Pt/BiVO₄/Co₃O₄ for degradation of CBZ is 54 times that of Co₃O₄/BiVO₄ and 2.5 times that of Pt/BiVO₄, which shows a synergetic effect in the photocatalytic activity. The same synergetic effect is also observed for Pt/BiVO₄/MnO _x . The spatial separation of the reduction and oxidation cocatalysts could reduce the recombination of the photogenerated charges, which mainl
