제목 Preparation of Mesostructured Material using Deironed Illite Reformed by DBD Plasma
초록 Mesoporous materials designed with hydroxyl groups on the surfaces within illite structure reformed by the dielectric-barrier discharge (DBD) plasma were investigated in this study. The chemical composition of the used illites was as followings; aCTMACl: bIllite: c EtOH: 5000 H2O (a: 0.5-3, b:0.1-1.5, c: 1-5). All reactions were carried out between 313K and 423K under various pH conditons. The crystallized framework was characterized by means of PXRD, TGA, TEM and nitrogen adsorption. Results of XRD and FTIR spectroscopy showed the significant changes between illite samples after and before plasma treatment. Author suggests that after disintegration of the illite layers under specific condition, the fragments of these layers aggregate to form pore around CTMA+ ions. This implies that silanol groups, Si-OH, or siloxyl anions, Si-O-, on the surface of illite reformed by DBD plasma are interacted as hydrogen bonding with CTMA+ and form mesopore whereas the formed mesopore structure aggregated to form the wall of the mocropores. The results agreed with t-plot with typical mesoporous materials containing micropores.
