Green synthesis and characterization of zinc ferrite (ZnFe 2 O 4 ) nanocomposite via Tristaniopsis merguensis natural extract was performed. The precursors used in this analysis were Zn(NO 3 ) 2 .6H 2 O and Fe(NO 3 ) 3 .9H 2 O, it was known that the extracts of Tristaniopsis merguensis leaves had high total phenolic content. Synthesis is carried out by comparing the temperature without annealed and annealed at 700 °C. The presence of phenolic compounds in the extract of Tristaniopsis merguensis functions as a bioreductor agent and chelating agent in the formation of zinc ferrite material. The XRD analysis showed the diffraction peaks typical of ZnFe 2 O 4 at 29.98°, 35.85°, 42.75°, 56.51° and 62.09° at 700 °C annealed, indicating that the ZnFe 2 O 4 structure had a face center cubic structure with miller index (220), (311), (400), (400) and (400). The average particle size of ZnFe 2 O 4 is 9.0414 nm based on Scherrer’s calculations. FTIR analysis shows the presence of phenolic compounds in Tristaniopsis merguensis leaves extracts interacting with Zn 2+ and Fe 3+ ions producing sharp absorption at wave number 543.80 cm −1 corresponding to the vibrational mode of the metal oxygen bond (Zn-O-Fe).
