摘要: Titania supported Au–Co catalysts with nano- and sub-nanoparticles, were prepared 1% Au different contents of cobalt by one pot deposition precipitation urea. Monometallic gold also the same method for a comparative purpose. The characterization bimetallic catalyst evidenced presence sub-nanoparticles where 50% 40% particles are smaller than 1 nm formation particles. results show positive effect on size catalytic activity. effectiveness these in synthesis several propargylamines via amine, CH2Cl2 alkyne coupling (AHA coupling) was demonstrated. Different synthesized very good yields (71%–88%). A study monometallic gold, gold–cobalt investigated. most efficient reused up to six reaction cycles without significant activity loss.
