Construction of Cerium-Based Nanozymes
Creative Enzymes provides services to customers worldwide in the field of the construction of cerium-based nanozymes. Our platform is equipped with cutting-edge facilities and professional experts to support nanozyme research. Here, we provide various services according to customers' requirements.
Customized Cerium-Based Nanozymes Construction Services
| Nanozymes Features | Mimical Enzyme Activity | |
|---|---|---|
| Cerium Oxide (CeO2) Nanozymes | An ideal material for nanozyme because it not only has excellent biocompatibility; but also has ample oxygen vacancies that can realize the valence conversion between Ce3+ and Ce4+. | Catalase-like and superoxide dismutase |
| CeVO4 Nanozymes | The enzyme activity of the CeVO4 nanozymes depends on the relative ratio of surface Ce3+ / Ce4+ ions, the presence of V5+ and the surface-Cyt c interactions. | Cytochrome c oxidase (CcO) and superoxide dismutase |
| Pt / CeO2 Nanozymes | The property of strong stabilization is related to the stability of Pt2+ ions within square-planar [PtO4] moieties on the surface of nanostructured CeO2. | Catalase-like and superoxide dismutase |
| MOF / Ce Nanozymes | MOF / Ce nanozymes are of special interest due to the combination of microporosity, the Ce(III) / (IV) redox properties and the presence of low-energy 4f orbitals. | Heterogeneous catalysis and heterogeneous photocatalysis |
Cerium Oxide (CeO2) Nanozymes Construction Services
- The catalytic performance of nanozymes depends primarily on the difference in specific surface area, crystal surface and valence caused by material morphology and structure.

- Creative Enzymes helps our clients synthesize cerium oxide nanozyme with diverse morphology and flexible size for research purposes, including spherical, flake, bulk, rod, octahedral, spindle and other shapes.
CeVO4 Nanozymes Construction Services

We provide CeVO4 nanozymes using synthetic methods such as solvothermal, sonochemical, hydrothermal and other methods. It can form different structures, for example cube-like, tiny flake-like and so on.
Pt / CeO2 Nanozymes Construction Services
- We provide Pt / CeO2 nanozymes that were synthesized by co-precipitation.
- The introduction of other active metals will be selected as an effective strategy to increase the catalytic activity of cerium oxide materials. Therefore, we also provide composite nanozymes based on CeO2 that have outstanding performance in a variety of catalytic reactions, such as Fe / CeO2 nanozymes, Co / CeO2 nanozymes, Mn / CeO2 nanozymes, Cu / CeO2 nanozymes and so on.
MOF / Ce Nanozymes Construction Services
The most common strategies for the synthesis of MOF / Ce nanozymes are based on the use of water and / or DMF in solvothermal reactions and employing Ce(NO3)3 · 6H2O or CeCl3 as the metal source.
Cerium-Based Nanozymes Related Services
After the construction of cerium-based nanozymes, we also provide determination of peroxidase activity, catalase activity, superoxide dismutase activity and others, measure of catalytic kinetics data as well as stability tests. Our one-step service will help our clients make progress in research.
Creative Enzymes provides cost-effect, high quality and hassle-free services to our clients worldwide. We provide our clients with direct access to our experts as well as prompt respond to their inquiries. If you are interested in our services, please feel free to contact us or make online inquiry.
