| Abstract: | Nanoporous copper (CuNPore) catalysts with tunable nanoporosity were fabricated from Cu30Mn70 alloy by controlling the de‐alloying temperature under free corrosion conditions. The tunable nanoporosity of CuNPore led to a significant enhancement of catalytic activity in click chemistry without using any supports and bases. Characterization of CuNPore surface, high reusability, leaching experiment, and formation of nanostructured copper acetylide revealed that the click reaction occurred at the catalyst surface. |
