X-ray absorption fine structure spectroscopy determination of the binding mechanism of tetrahedral anions to self assembled monolayers on mesoporous support

X-ray absorption fine structure (XAFS) spectroscopy is used to investigate the chemical interaction between the end member [Cu(NH₂)₆] of self-assembled monolayers on mesoporous supports (SAMMS) and the tetrahedral anion SO₄. The local structure about Cu indicates monodentate bonding between the SO₄ anion and the SAMMS.
