| Abstract Scope |
The green chemical synthesis of copper nanoparticles (CuNPs) is an alternative which uses chemicals and processes that reduce or eliminate the use and generation of toxic substances, such as ascorbic acid, cyclodextrin, plant extracts, chitosan and gelatine. In this study, precursor solutions of copper sulfate pentahydrate and ascorbic acid were used. The synthesized CuNPs were characterized by UV-vis, EDS, SEM and XRD. The presence of Cu oxide particles and CuNPs was inferred through UV-vis. In the images and compositions of the SEM-EDS were found oxygen and Cu, as well as particles of non-uniform size and morphology. The results showed that at pH 5, agglomerated CuNPs were found. XRD verification was performed on the particulate at pH 5 in which diffraction peaks were attributed to copper structure planes (with dimensions of 1042nm to 3.34nm) and other CuO and Cu2O diffraction peaks that overlapped with Cu phases. |
