Nanozyme-Based Catalytic Degradation of Pollutants

Human activity is already causing serious pollution in our environment. Many toxic pollutants, including heavy metals, dyes and other organic and inorganic substances, are produced in the production of goods or during their use. Due to a lack of regulation and awareness, many toxic compounds have been released into the environment, especially in aquatic environments such as lakes, rivers and oceans. These pollutants cause significant damage to our ecosystems, including humans, plants, animals and microorganisms. They have been identified as a cause of toxic and carcinogenic effects in humans through contamination of drinking water and food.

Great effort has gone into remediation to remove these contaminants or to degrade them into less harmful products. Biocatalytic methods have been investigated as an effective means of degrading organic pollutants. However, nanozymes have shown catalytic properties, such as peroxidase and oxidase-like, and they can be used to degrade contaminants by native enzymes. More importantly, nanozymes can overcome the limitations of enzymes in terms of production cost, recyclability, higher reaction rates, and a wider range of operational scenarios. Creative Enzymes, as a leading global company, is committed to helping our clients achieve effective and successful research. We develop types of nanozymes and schemes for degradation of pollutants, including phenolic, dye, and antibiotic pollutants.

Fig. 1 The degradation processes of organic pollutants by nanozymes.

Catalytic Degradation of Phenolic Pollutants with Nanozymes

• Phenolic pollutants are widely distributed in surface water and groundwater, they have attracted international attention due to their high toxicity. Such pollutants not only enrich organisms and inhibit their growth, but can also be transmitted through the food chain, such as water, organisms and animals, endangering human health.
• As an efficient catalyst, nanozymes can be used to catalyze the coupling reaction of phenolic pollutants in water. Nanozymes can avoid the limitations of natural enzymes in practical applications.

Catalytic Degradation of Dye Pollutants with Nanozymes

• Synthetic dyes have many advantages, so they are widely used in textile, food, rubber, medicine and other fields. However, many factories do not have sewage treatment facilities. As a result, most of the dye wastewater is discharged directly into natural water. According to related reports, most dyes are refractory to degradation, and these dyes may eventually enter the body along biological chains.
• In this situation, Creative Enzymes develops methods to degrade of dye pollutants with nanozymes, including Fe₂GeS₄, CuO / Ti₆O₁₃, Fe₃O₄ nanozymes and others.

Catalytic Degradation of Antibiotic Pollutants with Nanozymes

• Antibiotics are widely used in clinical medicine, which can fight pathogenic bacteria and treat diseases caused by bacterial and other microbial infections in the human. In addition, some antibiotics can have an immunosuppressive effect. However, antibiotics are widely used in a variety of situations, leading to the discharge of antibiotic waste into rivers.
• As a new technology for pollution treatment, nanozymes have the characteristics of green environmental protection and low cost, so they can also degrade antibiotics in water.

Catalytic Degradation of Pesticide Organic Pollutants with Nanozymes

There are many types of pesticides with complex structures and strong toxicity to living organisms. Neither specific adsorption methods nor biodegradation methods can effectively remove pesticide residues. Degradation techniques based on nanozymes can efficiently remove different types of pesticides by ignoring structural differences in pesticides and environmental conditions.
