Preparation and characterization of TiO2-nanotube/Ti plates loaded Cu2O nanoparticles as a novel heterogeneous catalyst for the azide–alkyne cycloaddition

• Cu2O-NPs/TiO2-NTs/Ti plates were prepared by electrodeposition of Cu2O nanoparticles on TiO2 nanotubes.
• The plates are applied for the azide–alkyne cycloaddition.
• Excellent yield has been achieved.

Cu2O-NPs/TiO2-NTs/Ti plates were fabricated via electrodeposition of Cu2O nanoparticles on TiO2 nanotubes previously formed by anodizing of titanium. Microstructure studies show that nanoparticles of Cu2O having high surface area have been deposited on the walls of as-prepared TiO2 nanotubes. The catalytic activity of plates was tested for azide–alkyne cycloaddition. The results of catalytic experiments demonstrate that the Cu2O-NPs/TiO2-NTs/Ti plate exhibits significantly enhanced catalytic activity for the azide–alkyne cycloaddition.
