| 报告介绍 | In the decades to come, mankind will have to make a significant shift in the way it deals with our planet’s available resources, and in particular in our use of energy. It is not difficult to argue that the sun is the only sustainable source of energy available to us, and electrochemistry and catalysis will play a key role in harvesting, storing and releasing that energy.
In the talk, I will first summarize the application of the Sabatier principle to multi-electron transfer reactions and demonstrate how the rate of such reactions crucially depends on the free energy relations between intermediates. Next I will discuss experimental examples of various relevant reactions: carbon monoxide oxidation and reduction, water oxidation, and nitrite reduction, studied on single-crystalline electrodes in an electrochemical cell, using a variety of experimental and computational methods. From such studies, we can derive conclusions for suitable nanomaterials for real devices.
