Resource Recycling of Carbon Dioxide with Catalysis by Heteromultinuclear Metal Complexes

我们开发了用于二氧化碳电化学和光化学还原的方法和新材料。取得了以下进展：-我们建立了一种新的仪器，用于金属络合物催化的电化学还原产物的自动分析。它无需人工处理即可同时对气相和液态进行采样和分析。-我们提出了一个新的概念--“二元配体”，它使第一排过渡金属络合物的合理设计和合成成为可能。这些配合物在重复氧化还原循环下是稳定的，因此适合于电化学还原。我们还成功地利用这些配体进行了光化学反应和多核金属配合物的合成。-我们利用对苯二酚/对苯二酚氧化还原体系开发了新的光化学体系。这些系统对二氧化碳的捕获和化学还原很有用。

We developed methods and new materials for use in electrochemical and photochemical reduction of carbon dioxide. The following progress was made:- We built a new instrument for automatic analysis of products from electrochemical reduction catalyzed by metal complexes. It performs simultaneous sampling of gas and liquid phases and analysis without manual processing.- We proposed a new concept, "binary ligands," that enables rational design and synthesis of first-row transition metal complexes. These complexes are stable under repetitive redox cycles and thus suitable for electrochemical reduction. We also succeeded in photochemical reactions and synthesis of multinuclear metal complexes by use of these ligands.- We developed new photochemical systems by use of quinone/hydroquinone redox systems. These systems are useful for capture and chemical reduction of carbon dioxide.
