Abstract

Cerium dioxide nanoparticles are a promising material in many industries, for example, catalysis, chemical industry, biomedicine. Cerium ions located on the surface of nanoparticles easily enter into redox reactions. To increase the activity of such nanoparticles, it is necessary to increase the nonstoichiometry of nanoparticles by increasing the ratio of Ce3+/Ce4+ ions. The increase in non-stoichiometric nanoparticles of cerium dioxide is an important issue for increasing their catalytic activity. Annealing in a reducing atmosphere has been proposed as a method for increasing the concentration of Ce3+/Ce4+.Cerium dioxide nanoparticles are a promising material in many industries, for example, catalysis, chemical industry, biomedicine. Cerium ions located on the surface of nanoparticles easily enter into redox reactions. To increase the activity of such nanoparticles, it is necessary to increase the nonstoichiometry of nanoparticles by increasing the ratio of Ce3+/Ce4+ ions. The increase in non-stoichiometric nanoparticles of cerium dioxide is an important issue for increasing their catalytic activity. Annealing in a reducing atmosphere has been proposed as a method for increasing the concentration of Ce3+/Ce4+.

在还原气氛中退火的二氧化铈纳米颗粒的发光光学性质

二氧化铈纳米颗粒在催化、化工、生物医药等领域具有广阔的应用前景。位于纳米颗粒表面的铈离子容易进入氧化还原反应。为了提高纳米颗粒的活性，必须通过增加Ce3+/Ce4+离子的比例来增加纳米颗粒的非化学计量。增加非化学计量二氧化铈纳米颗粒是提高其催化活性的一个重要问题。在还原气氛中退火是提高Ce3+/Ce4+浓度的一种方法。二氧化铈纳米颗粒在催化、化工、生物医药等领域具有广阔的应用前景。位于纳米颗粒表面的铈离子容易进入氧化还原反应。为了提高纳米颗粒的活性，必须通过增加Ce3+/Ce4+离子的比例来增加纳米颗粒的非化学计量。增加非化学计量二氧化铈纳米颗粒是提高其催化活性的一个重要问题。在还原气氛中退火是提高Ce3+/Ce4+浓度的一种方法。
