Through the mussel-inspired chemistry, we were attempted to connect to the titanium dioxide nanoparticles (TiO2) on chemically reduced graphene oxide (rGO) using a dopamine having a catechol group. The reduction of GO toward rGO coincided with the functionalization of PDA layer on rGO using dopamine, and TiO2/dopamine/rGO was prepared by connecting the polydopamine/rGO with TiO2 (P25) in aqueous tris-buffered silane (TBS) solution (pH 8.5). after that, TiO2/Dopamine/rGO prepared spontaneously is able to adsorb pollutants such as methylene blue to the surface of graphene, result from pi-pi interaction and van der Waals interaction. we was also successfully attempted to provide photocatalytic activity regarding degradation under either ultraviolet or even visible light. 2019년 한국교통대의 지원을 받아 수행하였음. |
