Abstract: Provided is a palladium on carbon (Pd/C) catalyst obtained by using an ionic liquid, a method for preparing the same, and a method for hydrogenation of hydrofluorocarbon using the same. More particularly, palladium particles are supported on carbon particles by using an ionic liquid, and the resultant Pd/C catalyst is used for hydrogenation of hydrofluorocarbon. The catalyst includes palladium particles having a smaller particle size and a more uniform shape as compared to the existing Pd/C catalysts, and thus shows high catalytic activity.

Abstract: The present disclosure relates to a hydroxyl group-containing amine-based sulfur dioxide and sulfurous absorbent, and a method for preparing the same. The absorbent uses an ionic liquid in the form of a salt including a diamine compound substituted with a hydroxyl group, and can be used as an absorbent capable of removing not only sulfur dioxide (SO2) but also sulfurous acid (H2SO3) formed by combination of sulfur dioxide with water.

Abstract: Disclosed is a method for adsorbing a dye for a dye-sensitized solar cell. The method includes: coating a paste including metal oxide nanoparticles on the upper surface of a titanium oxide thin film and calcining the coated paste to form a porous film; adding an additive to a sensitizing dye solution to promote the adsorption of the dye; and dipping the porous film in the sensitizing dye solution to adsorb the sensitizing dye onto the surface of the porous film. The sensitizing dye solution is a dispersion of the sensitizing dye in an organic solvent. Also disclosed are a working electrode prepared using the sensitizing dye solution and a dye-sensitized solar cell including the working electrode. The addition of the additive shortens the time of dye adsorption. Despite the shortened adsorption time, the dye does not undergo desorption in the long term as well as in the short term, ensuring long-term stability of the solar cell.

Abstract: Disclosed is a polymer gel electrolyte composition. The composition includes an aqueous solution of a polysaccharide-based polymer and a liquid electrolyte in which a redox derivative is mixed with an organic solvent. The composition is easy to inject. The composition is free from problems of leakage and volatilization, thus being environmentally friendly. Further disclosed is a highly efficient dye-sensitized solar cell using the composition. The dye-sensitized solar cell is stable for a long period of time and can be readily commercialized.
