제목 Adsorption of Organic dyes on TiO2@CaO through Calcium with Catechol Dye
초록  Adsorption of organic-dyes on Titanium dioxide nanoparticles has gained interest for the development of dye-sensitized solar cells. Catechol chemistry has important advantage that strong binding strength and applicable at many substances. The nanoparticles of core shell structure can provide multi-functional nano material exhibiting the characteristics of two or more. The Calcium ions with high affinity for Ca2+ adsorb to TiO2. Alizarin red S (AR) includes the Catechol ligand and shows a strong adsorption force in a variety of materials such as TiO2. AR is adsorbed on (TiO2 nanoparticle) because of complex formation of metal atoms on nanoparticle surface by two adjacent hydroxyl groups or adjacent carbonyl groups of AR. The adsorption between organic matter and inorganic matter is difficult but the use of catechol chemistry makes organic matter of AR adsorbed on inorganic matter such as TiO2 nanoparticle easier.
