Photocatalytic Degradation of RhB by SiC Nanowires
摘要
Abstract
The high purity monocrystal SiC nanowires are synthesized by carbonthermal reduction method. In different conditions, the photo catalysis degradation effect of SiC nanowires is studied when RhB is taken as the target breakdown products under 20 W UV lamp (λ = 253. 7 nm) . It is found that the RhB degradation reaches the best result under that condition of 0. 04 g SiC nanowires and pH 1. The degradation rate of RhB is 67. 63% when the illumination time is 6 hours. Kinetics analysis of different concentrations of RhB solution indicates that the degradation of RhB follows the first-order reaction kinetics model.关键词
