O presente artigo tem como objetivo avaliar a formação de pós de óxido deníquel-zinco (Ni0,75Zn0,25O) por meio da metodologia de síntese verde utilizando comomeio reacional particulados secos provenientes do rejeito do maracujá-amarelo(Passiflora edulis f. flavicarpa). Para obtenção do precursor, foi preparada uma soluçãoentre os nitratos, particulados de maracujá e água destilada, sendo disposta em umrefratário e submetida ao tratamento térmico nas condições de 353 K por 24 h. Oprecursor produzido foi calcinado nas condições de 673 e 773 K por 1h e os pós de óxidomisto foram caracterizados por meio das técnicas de Difração de Raios-X (DRX) eEspectroscopia de Infravermelho por Transformada de Fourier (FTIR). Com a técnicaalternativa de síntese, a partir das deconvoluções dos espectros de FTIR foramidentificadas as bandas vibracionais referentes as fases de ZnO e NiO em sua formaconjugada. Com os dados experimentais ajustados de DRX as fases cristalinas foramidentificadas e as amostras apresentaram tamanhos de grãos cristalinos médios de 52 e90 nm para as temperaturas de 673 e 773 K, respectivamente.
