Method of preparing core-shell copper nanoparticles immobilized on activated carbon and method of preparing chalcogenide compound using nanoparticles as catalyst

摘要

Disclosed herein is a method of preparing a Cu/Cu₂O core-shell copper nanoparticle catalyst having high catalytic activity from [Cu₃(BTC)₂] and NaBH₄ via a simple chemical reduction method. Also disclosed is a method of preparing a chalcogenide compound by using the nanoparticle catalyst as a heterogeneous catalyst in a cross-coupling reaction between a chalcogenide precursor compound and a boron-containing compound. The disclosed cross-coupling reaction is performed via a simple process, and the disclosed nanoparticle catalyst is compatible with various substrates under mild reaction conditions and exhibits excellent recyclability without a reduction in catalytic activity.
