Fig. 3. (a) Photocatalytic oxidation performance of BA over Pd nanoparticles, PdxS nanoparticles, CdS–PdxS NRs, CdS icosapods, physical mixture of CdS icosapods and PdxS nanoparticles, and CdS–PdxS icosapods under visible-light irradiation (λ > 420 nm). (b) Photocatalytic recycling tests for the CdS–PdxS icosapods. (c) Quenching experiments with different reactive species photocatalyzed by the CdS–PdxS icosapods. (d) In situ EPR spectra in N2 saturated CH3CN solution with the addition of DMPO.
