Phosphoric Acid Transfers Protons Cooperatively
High proton conductivity in liquid phosphoric acid arises from concerted transfer across chains of H3PO4 molecules rather than through individual transfer events (Nat. Chem., DOI: 10.1038/nchem.1329). Neat liquid phosphoric acid has the highest known intrinsic proton conductivity, and understanding the mechanism may help improve proton-conducting fuel-cell electrolytes. In the new work, a team led by Mark E. Tuckerman of New York University and Klaus-Dieter Kreuer of . . .
