氧化铈纳米酶的结构调控及POD酶活性研究

Study on the Structure Regulation and POD Enzyme Activity of Cerium Oxide Nanoenzymes

为探究CeO_(2)纳米粒子表面Ce^(3+)/Ce^(4+)比例变化对过氧化物酶(POD)活性的影响,以实现对POD催化反应的可控调节,本研究使用简易水热法合成CeO_(2)纳米粒子,并通过不同的气氛热处理来调控CeO_(2)纳米粒子表面Ce^(3+)/Ce^(4+)的比例来展开相关探索。

The impact of altering the Ce^(3+)/Ce^(4+)ratio on the peroxidase(POD)activity of CeO_(2)nanoparticles was investigated to achieve precise regulation of POD catalytic reaction.In this study,CeO_(2)nanoparticles were prepared by a facile hydrothermal method and controlled the surface Ce^(3+)/Ce^(4+)ratio of the nanoparticles by adjusting the atmospheres during the calcination process.
