As a p-type semiconductor material, cuprous oxide ([Cu.sub.2]O) has been paid much attention owing to its fundamental significance and widespread potential applications in solar cells, gas sensors, Li-ion battery, and catalysis [1-5].
For the cuprous oxide with the space group of Pn[bar.3]m, the numbers of oxygen ions per unit area on the (100) surface and on the (111) surface were estimated to be 2.78 and 8.83 [nm.sup.-2], respectively [9].
Transition metals, such as ferrous iron ([Fe.sup.2+]) or cuprous copper ([Cu.sup.1+]), play a pivotal role in cellular redox chemistry by reducing [H.sub.2][O.sub.2] to the highly toxic O[H.sup.*] radical (Fenton catalysis).

A satisfactorily working anode produces a dark grey, almost black film comprising Cuprous Oxide (CuO).
The iron was oxidized by the sulfur "in a continual and gradual manner" (Bateman, 1923), and this caused the solution to grade from cupric to cuprous as controlled by iron oxide availability.
This process utilizes ammonia-ammonium-sulphate solution and air to leach cuprous copper from chalcocite concentrates.
