ZnAlFe1−xSmxO4 (x = 0, 0.02, 0.04, 0.06, 0.08) spinel ferrites were successfully obtained for the first time via a sol–gel autocombustion technique using citric acid as combustion/chelating agent. These materials then employed photocatalysts degradation of Evans Blue, considered herein model organic pollutant. The XRD and FTIR analysis confirmed achievement pure ferrite structures all materials...
