In-Situ Electrochemical-Photoreduction Synthesis and Photocatalytic Performance of Pd/BiF3 Thin Films
In this study, the Pd/BiF3 thin films are successfully prepared by the facile in-situ electrochemical-photoreduction method from the Bi plates, and the photocatalytic performances of the BiF3 thin films with different mass fractions of Pd are investigated for comparison. The Pd/BiF3 thin films are characterized by the XRD, SEM, XPS and UV-Vis DRS methods. The photocatalytic performance of Pd/BiF3 thin films is investigated with rhodamine B (RhB) as the photocatalytic degradation object. Our characterization results indicate that when the noble metal Pd is loaded uniformly on the surface of BiF3 thin films and the mass fraction of Pd is 2.0%, the Pd/BiF3 thin films exhibit the optimal photocatalytic activity and stability for the degradation of RhB. In addition, there exist an obvious redshift of optical absorption bands and a decrease of bandgap from 3.70 eV to 3.03 eV. The capture experiment of active species confirms that when the mass fraction of Pd is 2.0%, the roles of the ·OH, ·
