Resolving Surface Reactions in Plasma Catalysis: Towards Rational Catalyst Design

Introduction

Renewable energy is key to tackling climate change and reducing our dependence on fossil fuels. The intermittent supply of renewable energy hampers its efficient usage and creates a pressing need for innovative energy conversion approaches.

Energy-to-Fuel Conversion

Energy-to-fuel conversion using plasma-assisted catalytic conversion (PLAC) is highly promising for producing urgently needed fuels from greenhouse gases. In PLAC, reactants are activated in a plasma discharge, allowing for remarkable efficiencies beyond the limits of thermal catalysis.

Catalyst Design

The catalyst surface defines the reaction pathway and selectivity, and is thus key in catalyst design. However, at present, the active state of catalyst surfaces in plasma is unknown, limiting the impact of PLAC by inhibiting the design of dedicated plasma catalysts.

Project Goals

In SURPLAS, I will overcome this challenge and unlock the full potential of PLAC by:

1. Determining the surface reaction mechanisms of catalysts in plasma.
2. Demonstrating the rational design of plasma catalysts for CO2 hydrogenation.

My expertise in surface reactions, materials design, and in situ spectroscopy forms the basis of a pioneering approach to analyzing surfaces while they are exposed to microwave plasma.

Collaborative Efforts

My group’s unique embedding with plasma experts from industry and academia will facilitate the study of complex catalyst-plasma interactions. I will be the first to determine the active state of single-crystal surfaces and applied powder catalysts in plasma and to derive trends in selectivity and metal-support interactions in PLAC.

Expected Outcomes

This breakthrough in understanding will allow for the rational design of plasma catalysts, which I will validate by catalytic performance measurements.

Conclusion

This project will revolutionize PLAC by demonstrating catalyst design based on atomic-scale understanding of surface reactions in plasma. SURPLAS will allow me to lead the way into a new era of energy conversion, at a time when urgent need for fuels meets record growth in renewable energy.
