“…Copper nanoparticles (Cu NPs) exhibit high potential in the field of nanoscience and nanotechnology due to their inexpensive cost and novel physiochemical characteristics; thus, they are being used to replace noble metal NPs. Recently, Cu NPs have been considered as promising catalysts for the oxidation of alcohols, 14 oxidation of CO, 15 C–C bond formation reactions, 16 C–heteroatom bond formation, 17 and various coupling reactions. 18,19 Unfortunately, thermodynamically unstable Cu NPs are prone to coalescence and agglomeration, resulting in a significant reduction in their catalytic activity.…”
