What is the impact of the 40-55 nm particle size range on the catalytic efficiency of ceria oxide nanoparticles?
The specified particle size range of 40-55 nm (TEM) indicates a polydisperse distribution rather than a monodisperse population. Since catalytic activity is surface-area-dependent, a broader size distribution can lead to variable performance in applications such as oxygen storage or polishing. The product's zeta potential of ~20 mV also affects available surface area in suspension, further influencing catalytic consistency.
Can this water-based ceria dispersion be mixed with organic solvents or biological buffers without aggregation?
This product is a water-based dispersion at 1 mg/mL with a zeta potential of ~20 mV, providing moderate electrostatic stabilization. Mixing with organic solvents, high-ionic-strength buffers, or other dispersions may destabilize the colloidal system, leading to aggregation. The compatibility with non-aqueous or biological media must be empirically tested before integration.
What does the zeta potential of ~20 mV imply about the long-term colloidal stability and storage requirements of this ceria dispersion?
A zeta potential of ~20 mV is near the threshold for moderate colloidal stability (typically ±30 mV indicates good stability). The product description lists this value and an appearance of milkwhite dispersion, suggesting that settling may occur over time. Specific storage conditions are not provided, but gentle shaking or sonication before use is recommended to redisperse any sediment.
This product is a 2.5 mL aqueous dispersion of ceria oxide nanoparticles (40-55 nm) with a zeta potential of ~20 mV, suitable for research use in catalysis, polishing, or biomedical applications where controlled particle size and colloidal stability are required.
Positive
- Controlled particle size and zeta potential: The TEM-verified 40-55 nm range and ~20 mV zeta potential indicate good colloidal stability and reproducibility for research applications.
- Aqueous dispersion at defined concentration: Pre-dispersed in water at 1 mg/mL simplifies handling and ensures consistent dosing for catalysis or materials synthesis.
Trade-offs
- Low concentration and small volume: The 1 mg/mL concentration and 2.5 mL package size limit total mass (2.5 mg), which may be insufficient for bulk or high-throughput experiments.
- Storage and handling sensitivity: As a colloidal dispersion, stability may be affected by temperature, pH, or contaminants; requires careful storage and handling to avoid agglomeration or sedimentation.
