The effect of pH on the synthesis of stable $ Cu_{2} $O/CuO nanoparticles by sol–gel method in a glycolic medium

Abstract In this work, we demonstrate that using a glycolic medium, both stable CuO and $ Cu_{2} $O nanoparticles can be elaborated from Cu colloidal particles by adjusting their chemical environment, in particular the acido-basicity of the solution. In this context, the effect of pH on the sol–gel...

520			\|a Abstract In this work, we demonstrate that using a glycolic medium, both stable CuO and $ Cu_{2} $O nanoparticles can be elaborated from Cu colloidal particles by adjusting their chemical environment, in particular the acido-basicity of the solution. In this context, the effect of pH on the sol–gel synthesis of $ Cu_{2} $O/CuO NPs was investigated. XRD results confirmed the formation of pure $ Cu_{2} $O with a cubic structure at lower pH (pH ≤ 6), whereas the pure monoclinic CuO was formed at higher pH (pH ≥ 12). TEM image indicates that the as-formed CuO NPs in basic pH are spherical in shape and their average size is found to be in the range of 4.5 nm. However, the as-obtained $ Cu_{2} $O NPs in acid pH are cubical, with an average diameter of about 3 nm, and agglomerated into large spherical particles under the effect of ethylene glycol. Using the UV–Vis spectroscopy, the measured band gap energies of the prepared $ Cu_{2} $O and CuO NPs are 2.07 and 4.08 eV respectively. FTIR results confirm the purity of the synthesized CuO and $ Cu_{2} $O nanoparticles.

In this context, the effect of pH on the sol–gel synthesis of $ Cu_{2} $O/CuO NPs was investigated. XRD results confirmed the formation of pure $ Cu_{2} $O with a cubic structure at lower pH (pH ≤ 6), whereas the pure monoclinic CuO was formed at higher pH (pH ≥ 12). TEM image indicates that the as-formed CuO NPs in basic pH are spherical in shape and their average size is found to be in the range of 4.5 nm. However, the as-obtained $ Cu_{2} $O NPs in acid pH are cubical, with an average diameter of about 3 nm, and agglomerated into large spherical particles under the effect of ethylene glycol. Using the UV–Vis spectroscopy, the measured band gap energies of the prepared $ Cu_{2} $O and CuO NPs are 2.07 and 4.08 eV respectively. FTIR results confirm the purity of the synthesized CuO and $ Cu_{2} $O nanoparticles.

In this context, the effect of pH on the sol–gel synthesis of $ Cu_{2} $O/CuO NPs was investigated. XRD results confirmed the formation of pure $ Cu_{2} $O with a cubic structure at lower pH (pH ≤ 6), whereas the pure monoclinic CuO was formed at higher pH (pH ≥ 12). TEM image indicates that the as-formed CuO NPs in basic pH are spherical in shape and their average size is found to be in the range of 4.5 nm. However, the as-obtained $ Cu_{2} $O NPs in acid pH are cubical, with an average diameter of about 3 nm, and agglomerated into large spherical particles under the effect of ethylene glycol. Using the UV–Vis spectroscopy, the measured band gap energies of the prepared $ Cu_{2} $O and CuO NPs are 2.07 and 4.08 eV respectively. FTIR results confirm the purity of the synthesized CuO and $ Cu_{2} $O nanoparticles.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cu2O</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Copper Acetate</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pure Cu2O</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Acetate Monohydrate</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cu2O Nanoparticles</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bahmad, L.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Laânab, L.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jaber, B.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied physics</subfield><subfield code="d">Berlin : Springer, 1973</subfield><subfield code="g">122(2016), 5 vom: 05.

title_auth	The effect of pH on the synthesis of stable $ Cu_{2} $O/CuO nanoparticles by sol–gel method in a glycolic medium
abstract	Abstract In this work, we demonstrate that using a glycolic medium, both stable CuO and $ Cu_{2} $O nanoparticles can be elaborated from Cu colloidal particles by adjusting their chemical environment, in particular the acido-basicity of the solution. In this context, the effect of pH on the sol–gel synthesis of $ Cu_{2} $O/CuO NPs was investigated. XRD results confirmed the formation of pure $ Cu_{2} $O with a cubic structure at lower pH (pH ≤ 6), whereas the pure monoclinic CuO was formed at higher pH (pH ≥ 12). TEM image indicates that the as-formed CuO NPs in basic pH are spherical in shape and their average size is found to be in the range of 4.5 nm. However, the as-obtained $ Cu_{2} $O NPs in acid pH are cubical, with an average diameter of about 3 nm, and agglomerated into large spherical particles under the effect of ethylene glycol. Using the UV–Vis spectroscopy, the measured band gap energies of the prepared $ Cu_{2} $O and CuO NPs are 2.07 and 4.08 eV respectively. FTIR results confirm the purity of the synthesized CuO and $ Cu_{2} $O nanoparticles. © Springer-Verlag Berlin Heidelberg 2016
