The Preparation And Properties Of Modified BiOI And BiOI/Cellulose Composite

As a usual natural macromolecular compound,cellulose has a unique structure.Because of the excellent physical,chemical and electronic properties,carbon nanotube have attracted much more attention.Bismuth oxyiodide is an efficient photocatalyst whose properties and modification have been the hot study region.Two different methods are used to prepare BiOI nanomaterials.By Fe,Co,Ni doping,M-BiOI is got.The characterization of the structure and properties are analysis with XRD,SEM,XPS and UV-vis.It is investigated to confirm the doping ratio and the best preparation condition.BiOI/cellulose composite is prepared by sedimentation going through discussing pH value,the ratio of carbon nanotubes.By the photocatalytic degradation of Methyl Orange as the object of study,the visible photocatalytic properties of M-BiOI,BiOI/cellulose composite and its strengthening mechanism are analysed,which provides the basis for studying new material in the photocatalytic degradation of pollutants.
