Research Abstract

The hydration structure of zinc ions confined in nanospaces of activated carbons was determined by XAFS and powder XRD measurements. XAFS spectra indicate that the distorted hydration structure whose structure is remarkably different from that in the bulk aqueous solution is formed in the nanospace. In addition, XRD band at d=2.0 nm was appeared for the aqueous solution confined in the nanospace whose average pore width is 0.7 nm, stemming from the ordering of molecular assembly of aqueous solution of zinc acetate.
