FOR 2213: Nanoporous gold - A prototype for a rational design of catalysts

研究单元2213将有助于理解纳米多孔金（npAu）的表面化学及其对结构和组成因素的依赖性，从而解释npAu氧化化学中的复杂和迄今为止部分不可预测的催化行为。详细了解低配位原子的作用，第二金属的作用和可能的基本步骤的范围，导致吸附的分子，特别是分子氧的活化，构成了在大学不莱梅和奥尔登堡，在技术大学汉堡-哈堡和在自由大学不莱梅的9个研究小组的财团的主要目标。三个领域将密切合作：材料的合成，旨在以可控和可重复的方式制备具有特定性能的npAu催化剂，气相应用（多相催化）和液相应用（催化和电化学）。在所有情况下，表面特性将与材料中的微观应变和孔隙率导致的质量传输特性一起考虑。这是联合体在过去三年合作后的延续方案。

The research unit 2213 will contribute to the understanding of the surface chemistry of nanoporous gold (npAu) and its dependence on structural and compositional factors allowing to explain the complex and so far partially unpredictable catalytic behavior in oxidation chemistry of npAu. A detailed understanding of the role of low-coordinated atoms, the role of second metals and the range of possible elementary steps leading to the activation of adsorbed molecules, particularly molecular oxygen, constitutes the main aim of the consortium of 9 research groups working at the University Bremen and Oldenburg, at the Technical University Hamburg-Harburg and at the Free University Bremen. Three areas will intimately work together: material’s synthesis, aiming at preparing npAu catalysts with defined properties in a controlled and reproducible fashion, gas phase applications (heterogeneous catalysis) and liquid phase application (catalysis and electrochemistry). In all cases, surface properties will be considered together with microscopic strain in the material and mass transport properties resulting from the porosity. This is the continuation proposal after the consortium has already worked together over the last three years.
