Las nanopartículas de óxido de cobre (NPCuO) son de interés debido a sus numerosas aplicaciones, entre las cuales destaca la catálisis, por los diversos procesos y reacciones en los que han sido empleadas. La síntesis de estas nanopartículas puede realizarse mediante distintos métodos y a partir de diversas fuentes. En el presente trabajo de investigación se emplearon dos precursores; una solución acuosa de una sal de cobre y una solución contaminada con el ion metálico, proveniente de una industria productora de sales. Se compararon las características estructurales y químicas de las NPCuO obtenidas mediante la técnica de reducción a partir de ambos precursores y se evaluó su desempeño como catalizadores en una reacción de síntesis de un triazol mediante la reacción “Click”. Los resultados demostraron que las NPCuO fueron activas catalíticamente y que el agua residual industrial puede constituir una alternativa para la síntesis de nanopartículas de óxido de cobre con actividad catalítica.
Copper oxide nanoparticles (NPCuO) are of interest due to their numerous applications, among which catalysis stands out as one of the most important, given the diverse processes and reactions in which they have been used. The synthesis of these nanoparticles can be carried out using different methods and from various sources. In this research, two precursors were used: an aqueous solution of a copper salt and a solution contaminated with the metal ion, obtained from a salt production industry. The structural and chemical characteristics of the NPCuO obtained by reduction from both precursors were compared, and their catalytic performance was evaluated in a triazole synthesis reaction. The results demonstrated that the NPCuO were catalytically active and that industrial wastewater can be an alternative for the synthesis of copper oxide nanoparticles with catalytic activity.
