Photocatalytic Activity of M(M=Mg,Ca,Sr,Ba,Ni)Nb_2O_6
Source abstract
Abstract
Powder samples,NiNb_2O_6,MgNb_2O_6,CaNb_2O_6,SrNb_2O_6,BaNb_2O_6,were prepared by solid state reaction.Crystal structure,optical and powder morphology of the samples were analyzed by XRD,UV-Vis diffuse reflectance spectra and SEM.The photocatalytic properties were investigated by degrading rhodamine B under UV irradiation.The substitution of alkaline-earth metals for Ni improves the photocatalytic activity of MNb206.After UV irradiation for 10h,the concentrations of RhB/SrNb_2O_6 suspension and RhB/BaNb_2O_6 suspension are degraded to 21% and 37%,respectively.
