biostudies-literatureUnknown7(49)Gys NAmino-alkylphosphonic acid-grafted TiO₂ materials are of increasing interest in a variety of applications such as metal sorption, heterogeneous catalysis, CO₂ capture, and enzyme immobilization. To date, systematic insights into the synthesis-properties-performance correlation are missing for such materials, albeit giving important know-how towards their applicability and limitations. In this work, the impact of the chain length and modification conditions (concentration and temperature) of amino-alkylphosphonic acid-grafted TiO₂ on the surface properties and adsorption performance of palladium is studied.
