Combined experimental and first principles look into (Ce, Mo) doped BiVO₄.

ABSTRACT: Here we investigated the effects of Ce and Mo doping on hydrothermally synthesized bismuth vanadate BiVO₄ nanoparticles (NPs). The existence of monoclinic scheelite and tetragonal zircon phases of NPs was validated from Rietveld refinement of the powdered X-ray diffraction, room temperature Raman, and Fourier-transform infrared spectroscopy. The co-doping of Bi and V sites with respective Ce and Mo dopants in a mixed tetragonal zircon and monoclinic scheelite phases of BiVO₄ lattice was corroborated from high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy. The photoluminescence measurements revealed enhancement of photo-generated carrier recombination in (Ce, Mo) co-doped BiVO₄ NPs which may have hampered its photocatalytic
