Tetrapodal ZnO (T‐ZnO) and aerographite networks represent two highly open porous (94.6 99.96%, respectively) model materials on which the impact of an atmospheric‐pressure plasma was studied for first time. The air treatment by a surface barrier discharge caused remarkable modifications T‐ZnO template, leading to large number oxygen vacancies. These observations were made using scanning electron microscopy (SEM) Raman spectroscopy. In second proposed set‐up, pellets material processed jet with pressurized nitrogen. Hexamethyldisiloxane (HMDSO) introduced as precursor into effluent nanoparticle deposition. Opposing trends in atomic concentrations versus distance source observed when gas (nitrogen or air) changed. More pronounced coverage occurred plasma. Their distribution SEM, energy‐dispersive X‐ray (EDX), Because higher oxidation treatment, deposited nanostructures appeared be mixture Si SiO x nanoparticles.
