The purpose of this study is to prepare a multifunctional gradient structure (gradient membrane or nanostructured alloy-metal oxide coupling) and explore the influence of icosahedral structure (Frank-Kasper phases and quasicrystals) on catalytic properties of different Oxidation-Reduction Reactions.The main work of this year is divided into three parts. The first part is to study the catalytic properties of Tsai-type 1/1 approximant crystals (ACs) such as Al-Pd-Sc, Ga-Pd-Sc. The activity of these catalysts and their selectivity for C2H4 were evaluated using simple C2H2 hydrogenation reactions with no surface oxidation. It can be found that substituting Ga with Al greatly improves the catalytic activity. DFT calculation shows that the adsorption energy of C2H2 on Al-Pd-Sc surface is higher, indicating that Al-Pd-Sc is more likely to adsorb gas molecules and promote the reaction. These findings can provide guidance for the selection of components in the preparation of gradient structures.In the second part, the Frank-Kasper phases (TCPs) related to quasicrystals is studied. There is a great number of icosahedral clusters in TCPs, and these clusters are aperiodic in IQC, but three-dimensionally periodical in TCPs. Our research indicate that TCPs (icosahedral clusters) are prone to generate stacking fault during formation, which provides a basis for the frequently found IQC structure in the TCPs.The third part explores whether Ga/In-Co-Ni/Cu can form quasicrystals. At present, there is no possibility of quasicrystals in these alloys with different compositions.

本研究旨在制备多功能梯度结构（梯度膜或纳米结构合金-金属氧化物耦合），探索二十面体结构（Frank-Kasper相和准晶）对不同氧化还原反应催化性能的影响，本年度主要工作分为三部分。第一部分研究了Al-Pd-Sc、Ga-Pd-Sc等蔡氏型1/1近似晶体的催化性能，通过简单的C2 H2加氢反应考察了这些催化剂的活性和C2 H4的选择性。结果表明，用Al取代Ga可大大提高催化剂的活性。DFT计算表明，C2 H2在Al-Pd-Sc表面的吸附能较高，说明Al-Pd-Sc更容易吸附气体分子，促进反应。这些发现可以为梯度结构制备中组分的选择提供指导。第二部分研究了与准晶相关的Frank-Kasper相。在TCP中存在大量的二十面体团簇，这些团簇在IQC中是非周期性的，而在TCP中是三维周期性的。我们的研究表明，二十面体团簇在形成过程中容易产生堆垛层错，这为二十面体团簇中常见的IQC结构提供了依据。第三部分探讨Ga/In-Co-Ni/Cu能否形成准晶。目前，在这些不同成分的合金中不可能存在准晶。
