The earth-abundant and inexpensive copper metal have generated a great deal of interest specially in the field of catalysis. This paper discusses the uses of Cu and Cu-oxide NPs as catalysts for Ullmann type reactions and Gas Phase Reactions. We believe that this article will provide the necessary background information for further study and applications of Cu-based nanoparticles in catalysis., International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2019, CSEIT194422
