Description

Synthesis of Mn/Fe Prussian Blue Analogues and Investigation on Its Catalytic Activity
FIELD OF THE INVENTION
The present invention that related to Mn/Fe PBAs predominated a significant potential in pharmacology, physics, biomedical engineering and many different fields.
BACKGROUND OF THE INVENTION
Nanozyme is nanomaterials which have the catalytic activity of nanozymes. Compare with a natural enzyme, nanozyme has the advantages of lower cost, easy preparation, higher stability, recycling utilization, which provides the bases for the application of industrial catalytic enzyme. Unlike natural enzyme, artificial nanozyme can remain 85% catalytic activity in harsh condition ( pH and temperature). nanozyme is widely applied in the medical, chemical industry and agriculture field. Wang Wen-teyenal etc. produced a metallic-oxide nanozyme which has better catalytic performance. Yang Ruitao etc. used a bimetallic metal-organic framework material as nanozyme for colourimetric detection of hydrogen perox1
2019101135 30 Sep 2019 ide[ 1], This research discovered that this bimetallic MOF material can act as peroxidase mimic enzymes and oxide mimic enzyme for the first time. Through the review of the previous studies home and aboard, scholars prepared nanozyme successfully through the hydrothermal method, sacrificial template, U-shaped tube for double scattering, common reduction methods.
Manganese-iron alloy, which is manganese and iron composition of the ferroalloy, used as a deoxidizer and alloy additives in steelmaking. It is the most frequently used ferrous alloy in this industry. Prussian blue (Fe7(CN)i8· 14H2O) is not only stable, incompatible with strong acids, strong oxidizing agents, ammonia but also light-sensitive. Zheng Wei etc. researched PBNPs (Prussian Blue Nano Particles) in-depth[2]. First of all, they found that PBNPs have the activities of several different mimic enzymes such as peroxidase (POD), catalase (CAT), superoxide dismutase (SOD) and ascorbate oxidase (AAO). Secondly, from the study of PBNPs’ catalytic mechanism, it is found that its POD-like activity is much higher than the that of iron oxide nanoparticles (IONPs). From the previous literature research, it is found that PBNPs follow the electron transfer mechanism while IONPs follow the Fenton reaction mechanism. A systematic safety assessment of PBNPs inside the human body was carried out, and the data from the safety assessment of PBNPs indicate that PBNPs is completely safe to human.
In this research, we dissolved the MnSO4- H2O and PVP in a mixture solution of ethanol and deionized water, which was marked as solution A. Then the aqueous solution of K3 [Fe (CN) 6] was slowly added into solution A under the magnetic
2019101135 30 Sep 2019 stirring. After centrifugation and washing followed by a drying process, Mn/Fe PBAs were obtained. This method was simple, speedy, easy to operate and was able to produce manganese iron in a large-scale. The catalytic activity of Mn/Fe PBAs was strong. These advantages made manganese-iron nanozyme a promising candidate for analytical application. The mechanism of detection of catalytic activity of nanozymes is that TMB is oxidized by OH radicals to oxTMB which is a blue substance. In this research, the best reaction condition was obtained by changing the pH value, temperature, TMB concentration and concentration of nanozyme respectively.
SUMMARY OF THE INVENTION
The purpose of the experiment was to find whether the Mn/Fe PBAs owned the chemical characteristic of catalytic activity, which always appeared in nanozyme. To explore the chemical characteristic of high catalytic activity on Mn/Fe PBAs, Mn/Fe PBAs was produced by the coprecipitation method. To exactly know the best condition of the production of Mn/Fe PBAs, the influence factors of the catalytic reaction, pH, the concentration of TMB, the concentration of Mn/Fe PBAs, and temperature during the reaction, were needed. Finally, it was ensured that Mn/Fe PBAs had the chemical characteristic of the oxidase-like catalytic activity and this high catalytic activity was for oxidation.
