Plasma Catalysis

Plasma catalysis combines plasma physics and chemistry to develop novel catalytic processes. This research area investigates how non-equilibrium plasmas can activate molecules and create reactive species that enhance chemical reactions. Investigations include understanding plasma-surface interactions, designing plasma reactors, and synthesizing materials that benefit from plasma treatment. Specific applications explored involve the conversion of greenhouse gases, the synthesis of valuable chemicals like ammonia, and the development of advanced materials with tailored properties. The fundamental science focuses on controlling plasma parameters to optimize reaction pathways and improve energy efficiency.

This research holds significant relevance for Arkansas’s agricultural and industrial sectors. For instance, advancements in ammonia synthesis can support fertilizer production, a key component of the state’s robust agricultural economy. Furthermore, the utilization of CO2 and the development of environmental remediation techniques can address challenges related to industrial emissions and water quality, benefiting the state’s natural resources and public health. The efficient conversion of small molecules also offers pathways for developing new chemical manufacturing capabilities within Arkansas.

The field draws upon expertise in materials science, nanoparticle synthesis, and semiconductor device fabrication. Research in plasma catalysis is inherently interdisciplinary, engaging with catalysis, environmental science, and chemical engineering. This work is conducted across multiple institutions within Arkansas, fostering collaboration and expanding the state's research capacity in advanced chemical processing and materials innovation.
