Synthesis plasmonic Bi/BiVO4 photocatalysts with enhanced photocatalytic activity for degradation of tetracycline (TC)
摘要
Abstract
In recent years
the excessive use of antibiotics has become a serious problem for human health. BiVO
4
regarded as one of the most promising visible-light-driven photocatalysts was used to degrade the antibiotics. In this paper
we fabricated Bi/BiVO
4
plasmonic photocatalysts which enhanced the photocatalytic activity of BiVO
4
for degradation of tetracycline (TC) antibiotic. The Bi/BiVO
4
photocatalysts were characterized by X-ray diffraction
X-ray photoelectron spectroscopy
scanning electron microscopy
transmission electron microscopy and high-resolution transmission electron microscopy. In addition
the photocatalytic experiment results show that the 0.04-Bi/BiVO
4
sample has the best photocatalytic activity for 2 times than the pure BiVO
4
photocatalyst. The cycle experiments
after four repetitions of the experiments
showed the sample still maintained a high photocatalytic activity. Finally
the photocatalytic reaction mechanism was also studied by free radical capture experiments and electron paramagnetic resonance spectroscopy.
