Environmental Treatment

Introduction

Environmental Treatment

Environmental treatment is a necessary prerequisite for maintaining the ecological environment and protecting biological diversity, and its importance cannot be ignored. In addition, environmental treatment can reduce pollution and waste emissions, protect natural resources, improve the stability and productivity of ecosystems, while improving the human living environment and ensuring people's survival and development. Since the 21st century, environmental pollution problems have become increasingly intensified, making the development of efficient and environmentally friendly environmental treatment measures an important topic for researchers. As nanozymes are becoming more and more known, their applications are found to be helpful in solving environmental pollution problems. They have high catalytic activity and can degrade organic pollutants in wastewater, degrade chemical warfare agents and inhibit marine biofouling. Furthermore, nanozymes are environmentally friendly, easy to recycle, and have good operational and storage stability under various environmental conditions. Based on the above advantages, nanozymes play a vital role in environmental treatment.

Applications

In the field of environmental treatment, nanozymes can be used to degrade organic pollutants in wastewater, degrade chemical warfare agents and inhibit marine biofouling.

Nanozymes in degrading organic pollutants in wastewater. Fe₃O₄ nanozymes are suitable for wastewater treatment. They can be used as peroxidase mimics to catalyze the degradation of phenols. In addition, Fe₃O₄ nanozymes also used for the catalytic decompositions of methyl blues, rhodamine B, and other organic substances. Furthermore, many other nanozymes with a peroxidase-like property have also been discovered to catalyze the degradation of organic pollutants. For example, the BSA-Cu₃(PO₄)₂·3H₂O hybrid nanozyme could be used as peroxidase mimics with excellent biocatalytic property, stability, as well as durability. In the presence of H₂O₂, this hybrid nanozyme could catalyze the decomposition of organic pollutants such as rhodamine B with high efficiency, demonstrating their possibility for treating wastewater^[1].

Nanozymes in degrading chemical warfare agents

Nanozymes in degrading chemical warfare agents. Chemical warfare agents refer to various chemical substances that are used for war purposes and have severe toxicity and mass destruction. Among them, nerve agents are toxic chemicals that destroy the normal transmission function of the nervous system. They are the most toxic type of chemical warfare agents today. As a new type of material that can effectively catalyze the degradation of nerve agents and similar substances, nanozymes have been widely used in the degradation of chemical warfare agents. They can catalyze the decomposition of organophosphorus nerve agents such as pesticide, paraoxon, parathion, malathion and the warfare agent O-ethyl S (2-diisopropylaminoethyl) methylphosphonothiolate (VX), dimethyl 4-nitrophenyl phosphate (DMNP), O-pinacolyl methylphosphonofluoridate (Soman), etc.

Nanozymes in inhibiting marine biofouling. Some nanozymes can be used as additives in ship antifouling coatings to inhibit the accumulation of marine microorganisms on ships. For example, CeO_2-x nanozymes possess inherent haloperoxidase-like activity. They can catalyze the bromination of the signaling compound N-(3-oxo-acyl)homoserine lactone (3-oxo HL) which impedes bacterial quorum sensing. When adding CeO_2-x nanozymes into coatings, they still retained high antifouling capacity and can effectively inhibit the adhesion of microorganisms, thus inhibiting marine biological pollution^[2].
