[PFCC Webinar] Professor Yasushi Sekine from Waseda University will be presenting ~Uncovering the mechanism of green, on-demand, highly efficient hydrogen production by ammonia decomposition in a low-temperature electric field~
We will hold a webinar in which Professor Yasushi Sekine (Waseda University) will talk about the following paper using Matlantis: Hydrogen production by NH₃ decomposition at low temperatures assisted by surface protonics
If you are interested in catalyst development or collaboration between simulation and experimental chemistry, please join us.
This webinar is also open to those who are considering using Matlantis or who would like to try it in the future.
However, please note that the content of the lecture does not include an introduction to the basic functions of Matlantis, so you will be able to enjoy the lecture even more if you review the overview of Matlantis (Atomistic simulation tutorial, Chapter 1, Introduction) before attending.

| Lecture name | Elucidation of the mechanism of green, on-demand, highly efficient hydrogen production by ammonia decomposition in a low-temperature electric field |
Overview of the lecture | Ammonia is considered a promising hydrogen carrier because it can be decomposed to produce hydrogen without emitting CO2. However, conventional decomposition requires high temperatures of around 400-500 degrees, which has been an obstacle to its practical use. In this study, we demonstrated that a high ammonia conversion rate can be achieved even at low temperatures of around 200 degrees by applying a direct current electric field to the Ru/ CeO2 catalyst. The effect of applying an electric field is to achieve a result that exceeds the equilibrium conversion rate, enabling economically efficient hydrogen production. Analysis of the reaction mechanism, combining spectroscopy and Matlantis calculations, revealed that the surface protons form an HN-NH intermediate, which leads to efficient hydrogen production. In the absence of an electric field, nitrogen desorption is slow and the reaction does not proceed easily, but the application of an electric field promotes the transfer of surface protons, and the reaction proceeds via the N 2 H 2 intermediate, demonstrating that a high ammonia conversion rate of over 90% can be achieved even at low temperatures of around 200 degrees. |
