Citrus bio-residues play an importantrole in obtaining different materials through the solgel method. This method is a friendly technique.These waste consists of organic compounds with awide variety and chemical reactivity. In this way, ithas been recognized that this kind of waste, generatedmostly by the food industry, has an important potential to obtain silica to be used as a catalyst support.Provided that the principles of green chemistry andcircular economy are present. This work aims to usethe peel and juice of orange bio-residues, in acidic hydrolysis to obtain sol-gel silica. FT-IR spectra confirmsilica formation according to the centered band at1070 cm-1. In addition, SEM and TEM images of thesynthesized materials were compared to a referencesample to contrast their morphology. Strictly speaking, orange bio-residues promote silica polymerization, due to the availability of complex organic compounds and their abundant acidic contribution.
