Electrocatalysis of CO2 reduction

二氧化碳的电化学还原可用于隔离二氧化碳排放，储存多余的电能，为燃料电池和工业原料提供非气体燃料，并为受限空间提供大气控制。加拿大可以对环境作出重要贡献，并将从此类技术的开发和营销中获得巨大利益。这项建议是基于之前的调查结果。我们发现一种新的二吡嗪基吡啶配体的羰基二氯铀络合物在一个非常容易接近的电势下作为二氧化碳还原的电催化剂。这项研究的目的是将这种有希望的催化剂应用到工作装置中，并开发出具有更高效率的新的候选电催化剂。科学方法有三个阶段。第一个步骤是将催化剂吸附到电极表面，相关的测试和使用修饰电极构建电池。第二阶段包括相关催化剂的准备和评估，这些催化剂将从当前设计的电子较少的版本中以较低的电位运行，然后像以前一样并入电池。第三阶段要求创建双功能催化剂，以促进通过质子穿梭侧链进行质子耦合电子转移

The electrochemical reduction of carbon dioxide can be used to sequester carbon dioxide emissions, store excess electrical energy, provide non-gaseous fuels for fuel cells and industrial feedstocks, and provide atmospheric control for confined spaces. Canada can make important environmental contributions, and stands to benefit enormously from the development and marketing of such technologies. This proposal is based on previous findings. We have found that a arbonyldichlororuthenium(II) complex of a new dipyrazinylpyridine ligand acts as an electrocatalyst for carbon dioxide reduction at a very accessible potential. The proposed research aims to implement this promising catalyst in a working device and to develop new candidate electrocatalysts displaying increased efficiency. The scientific approach has three stages. The first involves the adsorption of the catalyst onto electrode surfaces, associated testing and construction of a cell using the modified electrode. The second stage involves the preparation and evaluation of related catalysts that will operate at lower potentials from electron-poorer versions of the current design, then incorporation into a cell as before. The third stage calls for the creation of bifunctional catalysts facilitating proton-coupled electron transfer via a proton-shuttling side-chain for
