METHOD FOR PREPARING CORE-SHELL TYPE COPPER NANOPARTICLES IMMOBILIZED ON ACTIVATED CARBON AND METHOD FOR PREPARING CHALCOGENIDE COMPOUND USING SAME AS CATALYST

摘要

The present invention relates to a method for preparing a Cu/Cu_2O core-shell type copper nanoparticle catalyst having high catalytic activity by using [Cu3(BTC)_2] and NaBH_4 through a simple chemical reduction process, and a method for preparing a chalcogenide compound by using the core-shell type nanoparticles as a non-homogeneous catalyst for a cross-coupling reaction between a chalcogen precursor compound and a boron-containing compound. The cross-coupling reaction according to the present invention includes simple processing steps, has compatibility among various substrates under a mild reaction condition, and shows excellent reusability without degradation of catalytic activity.;COPYRIGHT KIPO 2016
