Flower-like Ceria Nanoparticles

Product Name Name:Flower-like Ceria Nanoparticles Product Overview Rare earth metals and compounds play important roles in both traditional processes and high-tech fields such as information technology, biotechnology, chemical synthesis, and waste treatment. Among various rare earth metal oxides, ceria has attracted much attention due to its reversible transition between +4 and +3 valence states. This valence state transition ability endows it with the functions of oxygen storage and activation, thereby endowing it with catalytic performance. In addition, its diverse enzyme mimicking activities have promoted the application of various ceria nanomaterials as nanoenzymes in the biomedical field, from in vitro diagnosis (such as detection of glucose, glutathione, and adenosine triphosphate ATP) to in vivo treatment (such as tumor treatment), becoming one of the current research hotspots. Technical Parameter Particle size:30nm(TEM) Appearance:Yellow dispersion Product Features 1) Oxygen storage and release performance: Cerium element can achieve rapid reversible conversion between Ce³ ⁺ and Ce⁴⁺, and its reversible oxygen storage/release ability can store oxygen in oxygen rich environments and release oxygen in oxygen poor environments, maintaining local oxygen partial pressure balance in the catalytic region. Its catalytic activity is much higher than that of micron sized materials with the same composition. 2) Multi enzyme simulated activity: Nano ceria has the simulated catalytic function of various natural enzymes: superoxide dismutase (SOD) simulated activity; Catalase mimicking activity; Phosphatase mimicking activity, etc. 3) Photocatalytic performance: Ceria has excellent photocatalytic performance due to its semiconductor electronic structure and variable valence defect characteristics. Application Fields 1) Catalysis: Cerium dioxide nanomaterials have been widely used in energy catalysis and conversion, as well as automotive exhaust purification, due to their excellent reversible oxygen storage and release ability and structural stability. 2) Biological applications: Cerium dioxide nanomaterials have been proven to have good biocompatibility and multi enzyme simulation activity, which can simulate natural enzymes such as superoxide dismutase and catalase to scavenge free radicals. Therefore, they can be used as drug carriers or fluorescent probes for biological imaging for disease diagnosis; The photothermal effect of alloy nanoparticles can be used for photothermal therapy of cancer.
