摘要: The present invention relates to a method for producing a core-shell structure including a CdSe core based on a glyme solvent. The method of the present invention enables the production of a core-shell structure including a CdSe core in a simple and economical manner. The present invention also relates to a core-shell structure including a CdSe core produced by the method. The core-shell structure of the present invention includes a large amount of CdSe and is uniform in size. Particularly, the core-shell structure of the present invention can be coated on a flexible plastic substrate of an optical device or semiconductor device due to its high stability.

摘要: Disclosed is a hybrid catalyst system for the production of hydrogen/carbon monoxide syngas. The hybrid catalyst system includes a dye, a rhenium (Re) catalyst, and a cobalt (Co) catalyst grafted on a semiconductor metal oxide. The hybrid catalyst system can produce syngas without the aid of external energy and enables control over the ratio of hydrogen/carbon monoxide formed. Therefore, the hybrid catalyst system can find application in various industrial fields, including chemical fuel production.

摘要: A carbon dioxide reducing photocatalyst is provided. The carbon dioxide reducing photocatalyst comprises: an electron receptor comprising a metal oxide; a polymer concentrator deposited on the electron receptor; and a metal catalyst deposited on the electron receptor, wherein electrons move from the polymer concentrator to the metal catalyst through the conduction band of the electron receptor if the polymer concentrator absorbs light.
