Catalytic Degradation of Phenolic Pollutants with Nanozymes

Phenolic compounds have become a common organic pollutant in soil and groundwater due to their wide range of applications in wood-antimicrobial, pesticide, disinfectant and other fields. It is a serious threat to human health and the ecological environment due to its carcinogenic, reproductive toxic, neurotoxic and other properties. Natural enzymes such as peroxidase and phenol oxidase can be used as efficient green catalysts to catalyze coupled reactions with phenolic pollutants. However, the practical application of natural enzymes is limited by many environmental factors such as pH, temperature, metal ions, and natural organic matter.

Therefore, there is an urgent need to find new and effective artificial materials that mimic the catalytic oxidation properties of natural enzymes and efficiently remove phenolic contaminants from the environment. Creative Enzymes provides a variety of nanozymes for the catalytic degradation of phenolic pollutants, helping our customers worldwide in the nanozymes field.

Degradation of 2, 4-Dichlorophenol with Nanozymes

• 2, 4-dichlorophenol (2, 4-DCP) is a typical refractory phenolic organic pollutant with mutagenicity and carcinogenicity.

• Creative Enzymes synthesizes Fe₃O₄ / graphene nanozymes, classified into metal-organic framework enzyme catalyst, by a combination of mechanical and hydrothermal methods. It has been used as a heterogeneous Fenton photocatalyst for photocatalytic degradation of 2, 4-DCP with degradation efficiencies up to 100%.

Degradation of Catechol with Nanozymes

• Catechol, a phenolic compound commonly used in industry, is often discharged into aquatic ecosystems in large quantities through wastewater from industries such as textile, cosmetics, and food processing and manufacturing.
• We prepare Fe₃O₄ / CeO₂ metal oxide nanocomposites for efficient degradation of organic pollutants under simple conditions as Fenton heterogeneous mimic enzyme catalyst. It was shown that the catalyst has the significant advantage of multi-phase catalysis and is easy to select by magnetic separation. These properties make this type of catalyst reusable multiple times, and thus can greatly reduce the cost.

Degradation of Bisphenol A with Nanozymes

• In recent years, bisphenol A (BPA) has been found to be abundant in aquatic ecosystems due to excessive wastewater discharge.
• We use Fe₃O₄ nanozymes as a heterogeneous catalyst for the efficient catalytic degradation of BPA through the synergistic effect of ultrasound and catalytic reactions. We also modified the target nanozymes by evaluating the degradation rate of BPA in different systems.

Degradation of P-Chlorophenol with Nanozymes

• P-chlorophenol is an intermediate organic pollutant widely used in pesticides and organic synthesis with high stability and toxicity.
• We prepare Fe nanozymes complex by reduction method and use as heterogeneous H₂O₂ mimetic enzyme catalyst for degradation of p-chlorophenol.
