Summary of physicochemical characterization data of CuO nanoparticles.
| Physicochemical property |
Technique | Small CuO NPs | Large CuO NPs |
|---|---|---|---|
| Particle size (nm) | TEM* | 4 ± 1 | 24 ± 9 |
| Surface area (m2/g) | BET** | 118 ± 4 | 22 ± 0.4 |
| Bulk composition | XRD | CuO | CuO |
| Surface composition | XPS | Cu-OH, acetate | Cu-OH, carbonate |
Particle size obtained from TEM technique was expressed as mean ± SD and based on 100 particles.
Surface area obtained from BET technique was expressed as mean ± SD (n=3).
