【摘要】：以水熱法合成了不同形貌的BiOBr樣品.采用X射線(xiàn)衍射(XRD)、掃描電子顯微鏡(SEM)、氮?dú)馕矫摳角�(xiàn)和紫外可見(jiàn)漫反射光譜(UV-Vis DRS)研究溶劑對(duì)BiOBr樣品的晶形、形貌、孔徑分布和比表面積、光學(xué)性質(zhì)的影響;以羅丹明B(RhB)為目標(biāo)降解物,研究溶劑對(duì)BiOBr的可見(jiàn)光催化性能的影響.實(shí)驗(yàn)結(jié)果表明,采用EG為溶劑的BiOBr在可見(jiàn)光降解RhB中表現(xiàn)出最佳的降解效果,因其較采用HNO_3、GL和PVP為溶劑的樣品具有更高I_((001))/I_((102)),更小的禁帶寬度和更均一的納米片形貌.此外,闡述了溶劑對(duì)光催化降解RhB的影響機(jī)理.
[Abstract]:BiOBr samples with different morphologies were synthesized by hydrothermal method. The crystal shape, morphology, pore size distribution and specific surface area of BiOBr samples were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption and desorption curve and UV-Vis DRS. The effect of solvent on the visible light catalytic performance of BiOBr was studied with Rhodamine Bhb as the target degradation material. The experimental results showed that BiOBr with EG as solvent showed the best degradation effect in visible light degradation of RhB. As compared with the samples using HNO3GL and PVP as solvent, it has higher I / T / I / I / T, smaller band gap and more uniform morphology. In addition, the influence mechanism of solvent on photocatalytic degradation of RhB is described.
