Abstract

A novel heterostructured RuS₂-titanate nanohybrid has been prepared by reacting the exfoliated titanate sheets with the monodispersed RuS₂ nano-sol particles. At first the stable colloidal nano-sheets could be prepared by intercalating tetrabutylamine into layered protonic titanate, H_xTi_2-x/4□_x/4O₄·H₂O (x=0.67) with a lepidocrocite-like structure, and by successive exfoliating process in an aqueous solution. And then, the monodispersed RuS₂ nano-sol particles capped with 1-thioglycerol were hybridized with the colloidal titanate nanosheets. The final product was then heated at 400 °C for 1 h under N₂ gas atmosphere in order to complete the grafting reaction of intercalated RuS₂ nano-sol on the interlayer surface of layered titanate. X-ray diffraction indicated that the RuS₂-titanate nanohybrid has a pillar height of ∼1 nm. From UV-vis absorption spectra, it was found that the present nanohybrid showed visible light sensitization by RuS₂ nanoparticles with narrow band gap.
