Adsorption and photocatalytic oxidation of dimethyl sulfide and ethyl mercaptan over layered K_(1-2x)Mn_xTiNbO_5 and K_(1-2x)Ni_xTiNbO_5
二甲基硫和乙硫醇在层状K1-2xMxTiNbO5(M=Mn2+、Ni2+)上的吸附与光催化氧化作用

Layered K1-2xMxTiNbO5(M = Mn,Ni) was prepared by ion-exchange of KTiNbO5 obtained by the solid-state method with Mn2+ and Ni2+.The crystal structure and optical property of the as-prepared K1-2xMxTiNbO5 were studied by using powder X-ray diffraction and ultraviolet(UV)-visible light diffuse reflection spectroscopy.The adsorption feature and photocatalytic oxidation activity of dimethyl sulfide(DMS) and ethyl mercaptan(EM) over the as-prepared K1-2xMxTiNbO5 were evaluated using infrared spectroscopy.K1-2xMxT...
