Tech Brief: Dr. Marichas developed a novel process to overcome key process and cost barriers to scale-up nanoparticle catalyst fabrication for Proton Exchange Fuel Cells and Proton Exchange Electrolyzer. The process does not require intensive electrical power and reduce manufacturing cost more than 50%.

Value Proposition: For many advanced and diverse applications, ranging from chemical sensing, catalyst to magnetic recording, current research is increasingly focused on exploiting the high surface-to-volume ratios of nanoparticles as a framework for the assembly of complex nanomaterials. Structures including core/shell nanoparticles and multicomponent hierarchical assemblies can exhibit enhanced properties and new functionality arising from the close proximity of chemically-distinct, nanostructured components. Developing scalable fabrication processes that provide the necessary control of nanoparticle structure for enhanced activity presents significant techno-economic challenges for bringing nanoparticles to large-scale industrial catalytic applications. The proposed RSDT technology with controlled precursor injection and tightly controlled reaction zones for nanoparticle core-shell formation provides a unique continuous process approach for scaling up core-shell nanocatalyst fabrication and hierarchical assemblies at costs that are relevant for large-scale industrial applications. We will expect our process to be used in the electrochemical, and catalyst applications, i.e. PEM fuel cell anodes, cathodes, batteries, and chemical reactions for chemical conversion (dehydrogenation reactions) and gas purification (preferential CO oxidation).
