Information:
Copper (I) oxide (Cu2O/ CAS :1317 38 0) is a metal oxide semiconductor with promising applications in solar energy conversion and catalysis. To understand the Cu/Cu2O/CuO system at the nanoscale, we have developed a method for preparing highly uniform monodisperse nanocrystals of Cu2O. The procedure also serves to demonstrate our development of a generalized method for the synthesis of transition metal oxide nanocrystals. Cu nanocrystals are initially formed and subsequently oxidized to form highly crystalline Cu2O. The volume change during phase transformation can induce crystal twinning. Absorption in the visible region of the spectrum gave evidence for the presence of a thin, epitaxial layer of CuO, which is blue-shifted, and appears to increase in energy as a function of decreasing particle size. XPS confirmed the thin layer of CuO, calculated to have a thickness of ∼5 Å. We note that the copper (I) oxide phase is surprisingly well-stabilized at this length scale.
