The main goal of this research is to obtain carbon material (by pyrolysis of biomass in the presence of inert gas N2) and then physical activation with CO2 obtained active carbon material and finally chemical treatment (using TEOS - tetraethyl orthosilicate) enabled the creation of highly porous bio-SiO2 ceramics. The results of experiments of pyrolysis at several high operating temperatures, activation of carbon material and with multicycle action using TEOS clearly showed the possibility of obtaining SiO2 nanostructures, after carbothermal reduction to 600 °C. Increasing the activation temperature and the duration of the activation process initiates the development of SiO2 particles within the porous structure. The final SiO2 powder product was analyzed by several different test methods. Structure and morphology were analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). Surface chemistry and functional surface groups were determined by Fourier Transform Infrared... Spectroscopy (FTIR). The obtained results are guidelines for further study and understanding of the properties of SiO2 and for the possibility of its application
