abstract = {The main objective of this study was to assess the photoactive properties of iron-doped
silica xerogels under solar radiation. For this purpose, silica xerogels (XGS) synthesized by the sol-gel
method were doped with Fe (III) by two routes: impregnation and polymerization. XGS samples
were texturally and chemically characterized by N2 adsorption, XRD, FTIR, Raman, SEM-EDX, DRS,
and PL, evidencing the suitability of using XGS substrates to host iron clusters on their surface with
total compatibility. Chlorphenamine (CPM), ciprofloxacin (CIP), and ranitidine (RNT) were used as
model compounds. The degradation of the molecules was made under simulated solar radiation
testing the synthesis pad, load, material size, and reuse. It was found that XGS doped with Fe by
the impregnation route (XGS-Fe-Im) were able to completely degrade CPM and RNT in 30 min
and 10 min, respectively, whilst for CIP it achieved the removal of 60% after 1 h of solar radiation
exposure, outperforming parent materials and solar radiation by itself. The study of the degradation
mechanism elucidated a major influence from the action of HO  radicals. The present investigation
offers a potential route of application of XGS Fe-doped materials for the removal of emerging concern
contaminants under near real-world conditions.},
