Controlled reduction of Cu~(2+) to Cu~+ with an N,O-type chelate under hydrothermal conditions to produce Cu_2O nanoparticles

摘要

N,O-type organic chelates reduced coordinated Cu~(2+) ions under hydrothermal reaction conditions to produce Cu_2O/CuO nanoparticles. Chelates in which the N and O atoms are closely spaced produced smaller amounts of CuO nanoparticles, indicating their higher ability to reduce Cu~(2+) ions to Cu~+ ions. [Cu(Gly)_2]~2 with the shortest ligand chain length produced only Cu_2O nanoparticles and, therefore, can be used as a single molecule precursor for the synthesis of Cu_2O nanoparticles.
