Modeling surface chemistry and adsorption behavior of biomimetic chitosan/silica hybrid materials
Chitosan/silica hybrid powders, obtained by the sol-gel method (pH 6, 7, 8) are studied for proposing surface chemical models and rationalizing their behaviour as adsorbents. The chitosan and silica exposed groups in dried powders and their protonation state are inferred. Solid-state 29Si-NMR, XPS,...
