Synergism of Co/Na in BiVO₄ microstructures for visible-light driven degradation of toxic dyes in water.

ABSTRACT: In this work, we report a synergism of Co/Na in Co@Na-BiVO₄ microstructures to boost the photocatalytic performance of bismuth vanadate (BiVO₄) catalysts. A co-precipitation method has been employed to synthesize blossom-like BiVO₄ microstructures with incorporation of Co and Na metals, followed by calcination at 350 °C. The structure and morphology of the as-prepared photocatalysts are characterized by XRD, Raman, FTIR, SEM, EDX, AFM, UV-vis/DRS and PL techniques. Dye degradation activities are evaluated by UV-vis spectroscopy, in which methylene blue, Congo red and rhodamine B dyes are chosen for comparative study. The activities of bare BiVO₄, Co-BiVO₄, Na-BiVO₄, and Co@Na-BiVO₄ are compared. To evaluate the id
