      abstract     = {Several iron xerogel catalysts were synthesized by
                      hydrolysis and condensation of tetraethoxysilane (TEOS) and
                      3-(2-aminoethylamino)propyltrimethoxysilane (EDAS) which is
                      able to form a chelate with iron ions. The EDAS/TEOS ratio
                      strongly influences the texture of xerogel catalysts. The
                      specific surface area and the micro- and mesoporous volume
                      increase with this ratio. It seems that EDAS plays a
                      nucleating agent role for silica particles and allows to
                      anchor Fe-based moieties inside the silica network. Iron
                      oxide nanoparticles of diameter 1–1.5 nm and Fe3+ ions
                      result, encapsulated in silica particles with sizes of about
                      10–30 nm in diameter. The iron species was determined by
                      Mössbauer spectroscopy and magnetometry measurements and
                      only Fe3+ species were observed in xerogel catalysts. The
                      Fenton and photo-Fenton effect of these catalysts were
                      evaluated on the degradation of p-nitrophenol in aqueous
                      media under different conditions. Results show that in the
                      presence of H2O2, iron xerogel catalysts present a
                      photo-Fenton effect, reaching $99\%$ of degradation after 24
