Atrazine degradation through a heterogeneous dual-effect process using Fe-TiO₂-allophane catalysts under sunlight.

ABSTRACT: This study investigated the novel application of Fe-TiO₂-allophane catalysts with 6.0 % w/w of iron oxide and two TiO₂ proportions (10 % and 30 % w/w) for degrading atrazine (ATZ) using the heterogeneous dual-effect (HDE) process under sunlight. Comparative analyses with Fe-allophane and TiO₂-allophane catalysts were conducted in both photocatalysis (PC) and HDE processes. FTIR spectra reveal the unique hydrous feldspathoids structure of allophane, showing evidence of new bond formation between Si-O groups of allophane clays and iron hydroxyl species, as well as Si-O-Ti bonds that intensified with higher TiO₂ content. The catalysts exhibited an anatase structure. In Fe-TiO₂-allophane catalysts, iron oxide was incorporated through the s
