The obtained ferrites were then characterized through XRD, TEM, EDS, UV-vis, and SEM. XRD and TEM results exhibited cubic nanostructures with sizes ranging from 9 to 16 nm and 11 to 18 nm for ZnF and CoF, respectively. SEM images showed homogenous, porous flat surfaces. EDS spectra confirmed the successful synthesis of ZnF and CoF nanostructures with high purity. UV-vis spectra results of MB and MO dyes showed maximum sunlight absorbance in the absence of ZnF and CoF, while_{<span style="background-color:#ffffff;"> </span>}a regular decrease in the sunlight absorbance was observed in the presence of ZnF and CoF_{<span style="background-color:#ffffff;"> </span>}within 15-60 min. The UV-vis results also showed that ZnF had higher photocatalytic activity than CoF._{<span style="background-color:#ffffff;"> </span>}The experimental findings showed that the highest % degradation was 92.89% and 96.89% for MO and MB dyes, respectively, over ZnF compared to CoF_{<span style="background-color:#ffffff;"> </span>}photocatalyst (87.55% and 88.41% for MO and MB, respectively). These findings confirm that porous ZnF and CoF nanostructures are critical in promoting the degradation of dyes under sunlight instead of UV-vis light lamps that consume/require electrical energy.</span></span></span></span></span></span></span> Metallic ferrites,CoFe3O4,photocatalysts,methyl orange,ZnFe2O 1 12 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-4955-1&slc_lang=en&sid=1 Salihah Alkhobrani ummod07@hotmail.com 1800319475328460017316 1800319475328460017316 No Department of Chemistry, Faculty of Science, Al-Baha University, Saudi Arabia, Hossein Bayahia hbayahia@bu.edu.sa 1800319475328460017317 1800319475328460017317 No Department of Chemistry, Faculty of Science, Al-Baha University, Saudi Arabia Fares T.
