Abstract

Highlights New silica-based particles embedding iron were synthesized by freeze-drying-assisted sol–gel route. Fe O addition impedes the SiO crystallization denoting the glass network stabilizer role of iron. 2 3 2 3+ As 5 mol% Fe O is added to 0.7SiO ∙0.3Na O matrix Fe ions occur in a superparamagnetic phase. 2 3 2 2 Sodium release was noticed after washing the samples and immersion in simulated body fluid. Na release enhances porosity and facilitates the penetration of protons closer to inside iron ions. ● ● ● ● Keywords Silica-based particles Freeze-dried sol–gels Local structure XPS EDAX * S.
