Solution-Processed Synthesis of Copper Oxide (Cu x O) Thin
This article reports a solution-processed synthesis of copper oxide (Cu x O) to be used as a potential photocathode for solar hydrogen production in the solar water-splitting system. Cu x O thin films were synthesized through the reduction of copper iodide (CuI) thin films by sodium hydroxide (NaOH) which were deposited by the spin coating method from CuI solution in a polar aprotic solvent

Rapid combustion synthesis of Cu2Y2O5 as a precursor for
Mar 01 2018 · A simple rapid and energy saving combustion synthesis of Cu2 Y 2 O 5 microcrystals. Short combustion time <1 s ensures the obtaining of a reactive precursor mixture. The liquid phase combustion ensures a good homogeneity of precursors. The optimal annealing time at 1000 °C for pure phase Cu 2 Y 2 O 5 is around 5 min.
