Abstract

In this paper, nanoferrite (CdFe₂O₄-SnO₂) was prepared by the auto combustion method (sol-gel), with weight ratios of (x = 0.0, 0.05, 0.10, 0.15, 0.20, 0.25) for SnO₂. The properties of the nanoferrite were characterized by XRD, FE-SEM, and EDX techniques. The results showed that the produced compound had a cubic spinel ferrite phase; the crystallite size was determined using the Scherrer and Williamson-Hall equation. The FE-SEM image demonstrated that the compound is porous, with nanoscale particles that have a ball-like appearance. The EDX test verified the existence of Fe, O, Cd, and Sn atoms. Gas sensing showed the compound's high sensitivity to H₂S.
