| General description: | Copperis a versatile and widely used metal with significant importance in variousfields, particularly in catalysis and material science. In material science,copper is used in various conductive materials due to its excellent electricaland thermal conductivity, ductility, and corrosion resistance. Additionally,copper is also extensively used as a catalyst in various chemical reactions dueto its ability to facilitate electron transfer and promote redox reactions. Itoften acts as a catalyst in various reactions which include reduction, cross-couplingreactions and “click" chemistry (such as copper-catalyzed azide-alkynecycloaddition reactions. |
