Cost-effective and eco-friendly treatment or recycled use of poly (ethylene terephthalate) (PET) is highly desired. Enzymic PET degradation is considered a promising approach, but currently available PET hydrolases (PETases) have low activity at ambient temperature Thus, elevating the reaction system temperature in a cost-effective way becomes a key to the economical enzymic PET degradation Herein, we proposed solar-driven enzymic PET degradation with DuraPETase, a stable mutant of PETase, by using Fe3O4 nanoparticles (NPs) as the solar-to-thermal agent. Simulated solar irradiation could elevate the suspension of Fe3O4 NPs from 25°C to 46°C for the effective PET degradation The enzyme immobilized onto Fe3O4 NPs, DuraPETase@Fe3O4, had higher stability than free DuraPETase, but a 10-d PET degradation experiments under simulated solar irradiation revealed that free DuraPETase in the presence of Fe3O4 NPs was approx. three times more effective than the DuraPETase@Fe3O4 system because of the superiority of free DuraPETase in degrading PET. This implies that enzyme immobilization is unnecessary in such a single-use system. By contrast, the DuraPETase-only system showed only 15.5% efficiency of the Fe3O4-mediated solar-driven system with free DuraPETase. The research demonstrated the potential of the Fe3O4-mediated solar-driven enzymic PET degradation strategy for further development in different practical scenarios. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Electric Literature of C4H10O3).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Electric Literature of C4H10O3
