Abstract

Cuprous oxide (Cu₂O) and cupric oxide (CuO) particles were synthesized using a wet chemical surfactant free method at different synthesis temperatures from 25 °C to 60 °C. Morphology, size, and chemical composition of the prepared Cu₂O particles were analyzed by FESEM, PXRD, and UV-vis. We discovered that the chemical composition of the Cu₂O particles remained unaffected by the synthesis temperature. However, morphology and size of the particles showed a strong temperature dependency. This could be attributed to the temperature induced formation of CuO species from the copper hydroxide (Cu(OH)₂) precursor which also functions as copper precursor for the Cu₂O particle growth. The cupric oxide species was determined to be the main cause for the formation of micrometer sized particles, whereas with the Cu(OH)₂ precursor species for the Cu₂O particles nanocubes with smaller edge lengths as well as octahedrons were obtained.
