ABSTRACT

Affordable clean energy and climate action are two of the sustainable development goals set by the United Nations to be achieved by 2030. The vast majority of energy technologies relies on nanomaterials and their progress is strongly connected to the ability of materials chemists to tune their property- and function-dictating features. In this talk, I will present our recent group efforts towards the synthesis of atomically defined nanocrystals via colloidal chemistry. I will showcase how nanocrystals with precisely tunable shapes, sizes and interfaces serve as ideal platforms to advance our current knowledge towards improved selectivity in the electrochemical CO₂ reduction reaction. I will also share our results evidencing that these electrocatalysts can sustain their catalytic activity and selectivity at technologically relevant conditions, therefore might also offer practical solutions.

清洁能源和气候行动是联合国设定的到 2030 年要实现的两个可持续发展目标。绝大多数能源技术依赖于纳米材料；它们的发展与材料化学家调控其性质和功能决定的特性密切相关。在本报告中，我将介绍我们团队最近在通过胶体化学合成原子级确定的纳米晶体方面所做的努力。我将展示具有形状、尺寸和界面精确可调的纳米晶体如何作为理想平台来推进我们当前的知识，以提高电化学二氧化碳还原反应的选择性。我还将分享我们的结果，证明这些电催化剂可以在工业相关条件下维持其催化活性和选择性，进而为其实际应用提供可能。
