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.

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，从而能够解释npAu氧化化学中迄今部分不可预测的复杂催化行为。在不来梅大学和奥尔登堡大学、汉堡-哈堡工业大学和不来梅自由大学工作的9个研究小组的主要目标是，详细了解低配位原子的作用、第二金属的作用以及导致吸附分子，特别是分子氧激活的可能基本步骤的范围。三个领域将密切合作：材料的合成，旨在以受控和可重复的方式制备具有特定性质的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由孔隙率引起的质量传输特性一起考虑。这是该财团在过去三年里已经合作之后的延续提议。
