Efficient Fluorinating Agent through Topochemical Fluorination of Co−Fe Layered Double Hydroxides
Résumé
Mixed-metal inorganic fluoride, Co0.60Fe0.40F3, solid solutions are obtained through topochemical reactions of Co2FeCl(OH)6*2H2O LDH with molecular fluorine, F2, at temperatures as low as 100 °C. This solid solution possesses interesting F*-releasing ability, and its efficiency as a solid-state fluorinating agent is demonstrated on a commercial polyethylene film. 19F solid state NMR and contact angle measurements underline the efficient fluorination of this polymer.
