General description

Copper(I) oxide is a weak inorganic base that can be used to activate halides for nucleophilic substitution reaction. It is also used in decarboxylation and cyclo condensation reactions.

Application

Copper(I) oxide can be used:
  • As a precursor to prepare nanoparticles, nanocrystals, and quantum dots for various applications.
  • To catalyze the N-arylation of azoles under aqueous conditions using phase-transfer catalyst.
  • To prepare reduced graphene oxide-based nano copper composites applicable as a sensor for the detection of dopamine.
  • As a copper precursor to prepare Cu2O-TiO2 nanoparticle-based composite materials with aluminosilicate geopolymers applicable in the removal of organic pollutants from water.
