Abstract

The present work focuses on the study of the interaction of rare-earth oxides (REOs: La₂O₃, CeO₂, Pr₆O₁₁, Nd₂O₃, Sm₂O₃, Eu₂O₃, Gd₂O₃, Tb₄O₇, Dy₂O₃, Ho₂O₃, Er₂O₃, Tm₂O₃, Yb₂O₃, Lu₂O₃, and Y₂O₃) with hydrogen using the H₂-TPR technique. The temperature windows for surface and bulk H₂-TPR peaks of all nanocrystalline rare-earth oxides were determined and discussed in detail. A comprehensive analysis of the reducibility of rare-earth oxides was also conducted. This analysis identifies the pathways and general trends of the reduction processes in nanocrystallites of all rare-earth oxides — key information for their use in a wide range of scientific applications, such as heterogeneous catalysis and luminescent materials.

镧系氧化物还原性的H2-TPR综合研究

目前的工作重点是利用H2-TPR技术研究稀土氧化物（REOs: La2O3, CeO2, Pr6O11, Nd2O3, Sm2O3, Eu2O3, Gd2O3, Tb4O7, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3， Lu2O3和Y2O3）与氢的相互作用。测定了所有纳米晶稀土氧化物表面和体H2-TPR峰的温度窗，并进行了详细的讨论。对稀土氧化物的还原性进行了综合分析。该分析确定了所有稀土氧化物纳米晶体中还原过程的途径和一般趋势，这是它们在广泛的科学应用中使用的关键信息，例如多相催化和发光材料。图形抽象
