Abstract
Cobalt-aluminum layered double hydroxide (Co-Al LDH) is synthesized in the presence of functional amino-organic compounds, including glycine, acetamide and urea. Mixed cobalt-aluminum oxide nanoparticles were prepared from Co-Al LDH by the calcination method. The mixed oxides nanoparticles are characterized by a number of diverse techniques such as FTIR, TGA, XRD, SEM and TEM. The presence of functional amino-organic compounds affects the XRD patterns of Co-Al LDH and the computed lattice parameters. Thin films from Co-Al LDHs with 100 ± 5 nm thickness were fabricated by thermal evaporation method. The average optical energy gaps for Co-Al LDHs films were 2.325 eV with the optical characterization ratio of σ2:σ1 and ε1:ε2 resulted from thin film. Based on the obtained results mixed Co-Al oxides nanoparticles are considered promising alternative materials for producing clean and renewable energy and for enhancing the power conversion efficiency of the prototype of solar cell.
