The MxHyTi3O7 (M=K, Fe, Zn, Co, Na, Ag) nanotubes were prepared by ion-exchange reactions, in which H2Ti3O7 nanotube reacted with salts of K2SO4, Na2SO4, Fe(NO3)3, ZnSO4, Co(NO3)2 and AgNO3 in solution respectively. The properties of products were characterized by SEM, TEM, XRD and EDX. Synthesis of MxHyTi3O7 nanotubes by ion-exchanged process was proved by our experimental results. The adsorption properties of MxHyTi3O7 nanotube for methylene blue in aqueous solution were studied.
