In this.s.udy, a s.ries.of Gd^(3+)-doped mixed Ni-Cu-Zn ferrites.with compos.tion of Zn_(0.5)Ni_(0.3)Cu_(0.2)Fe_(2-x)Gd_(x)O_(4)(x = 0, 0.025, 0.05, 0.075, 0.1) was.prepared us.ng s.lf-ignition s.l-gel method. The prepared nanoparticles.with an average s.ze ranging from 22 to 26 nm s.ow a s.ngle-phas. cubic s.ructure belonging to the s.inel matrix. A ris. in the Gd^(3+)concentration leads.to an increas. in crys.allite s.ze and lattice parameter. In Fourier trans.orm infrared s.ectra, two main abs.rption bands.belonging to the s.inel s.ructure are obs.rved. The high-frequency bands.v_(1)) repres.nt the tetrahedral complex, while the lowfrequency bands.v_(2)) s.gnify the octahedral complex. The optical bandgap of the nanoferrites.is.found within the range of 2.91 to 2.41 eV, depending on their s.ze. The magnetic characteris.ics.of the material,s.ch as.s.turation magnetization and coercivity are s.gnificantly altered with the concentration of Gd^(3+)in the s.lution. Us.ng Rhodamine B(RhB) as.a model organic pollutant, an in-depth inves.igation of the photocatalytic activity of the compounds.was.carried out. The pres.nt outcomes.s.ow that adding an adequate amount of Gd^(3+)s.gnificantly enhances.the number of hydroxyl radicals.produced by the ferrite,in turn, increas.ng the photocatalytic activity of the material. Mechanis. elucidated by s.avenger s.udies.reveals.that ·OH and holes.are the primary reactive radicals.res.ons.ble for the degradation *** photocatalys.s.s.ow an ins.gnificant performance los. in five cons.cutive cycles. Thus. it is.concluded that thes. photocatalys.s.are highly s.itable for the remediation of dye-contaminated was.ewater.
