High-efficiency laser-irradiation spheroidizing of NiCo2O4nanomaterials
Abstract
We realized the desired spheroidizing of NiCo2O4nanomaterials by laser irradiating NiCo2O4suspensions with different concentrations. The results reveal that the as-prepared samples are desired spheres with the maximal average size of 568 nm and the superior dispersity, which were obtained at the energy density of 0.30 J·pulse-1·cm-2and NiCo2O4suspension concentration of 0.2 mg·mL-1. However, the phase segregation, which was induced by large amounts of solid redox of Co3+/Co2+and Ni3+/Ni2+, also appears in the laser-irradiation process.
