Abstract
We use X-ray powder diffraction to study heterogeneous solid-phase reactions induced by IR radiation in the system Cu(OOCCH3)2·H2O/PAN and intermediate copper compounds in the synthesis of copper nanoparticles. The composite Cu(OOCCH3)2 · H2O/PAN after annealing contains crystallites of copper (l Cu = 16 nm), a new metastable compound Cu x>2O (\( l_{Cu_{x > 2} O} \) = 20 nm), and Cu2O (\( l_{Cu_2 O} \) = 20 nm). After 45 days of air exposure, the intensity of Cu x>2O reflections in the composite decreases dramatically, whereas that of copper reflections increases. Cu x>2O has a monoclinic unit cell with the parameters a = 5.424, b = 3.196, c = 3.072 Å, β = 119.51°.
