β-Bi 2 O3的制备及光催化性能研究
Synthesis ofβ-Bi2 O3 and its VisibIe Light PhotocataIytic Performance
摘要
Abstract
β‐Bi2 O3 was synthesized by a precipitation method ,using cetyl‐trimethyl ammonium bro‐mide ,bismuth nitrate ,concentrated nitric acid and sodium hydroxide solution as raw materials .The as‐synthesized samples were characterized by X‐ray powder diffraction and ultraviolet‐visible spectropho‐tometer .The influence of temperature of NaOH solution on the formation of β‐Bi2O3 was systematically investigated .Moreover ,the influence of the addition of HCl on the visible light photocatalytic perform‐ance and corresponding intrinsic mechanism were studied .The experimental results show that the pureβ‐Bi2 O3 samples could be obtained when NaOH solution was heated to boiling (98℃) .The photoactivity of β‐Bi2 O3 was significantly improved ,due to the formation of BiOCl layer on the surface β‐Bi2 O3 ,which results in inhibited recombination of electrons and holes and thus improved photocatalytic performance .关键词
