About
Jonah Erlebacher is a professor in the Department of Materials Science and Engineering at Johns Hopkins University, with a secondary appointment in the Department of Chemical and Biomolecular Engineering. He joined the faculty of the Whiting School in 2000 and has been recognized for his advances in materials for energy technologies, computational materials science, and innovative methods for manufacturing nanostructured metals. His research focuses on developing methods for deep decarbonization of energy technology by transforming small molecules like methane and carbon dioxide into solid carbon, and upgrading low-value carbon into high-value products such as fiber, structural carbon, and biochar for permanent and safe sequestration. Additionally, he explores novel chemical pathways to produce hydrogen efficiently and at scale, utilizing experiments, process modeling, computational fluid dynamics, and prototype reactor systems. Erlebacher also works on creating and studying metal coatings that are highly resistant to corrosion and mechanical fatigue, employing experimental synthesis and multi-scale modeling. He holds multiple patents related to nanoporous gold leaf, advanced fuel cell catalysts, and methane decomposition processes. His contributions include developing computer models to simulate the morphological evolution of nanostructured materials over time. Erlebacher has received numerous awards, including the Johns Hopkins University Inaugural Gordon Croft Investment…

Three-dimensional bicontinuous nanoporous materials by vapor phase dealloying
Nature Communications · 2018-01-12 · 184 citations
articleOpen accessThree-dimensional bicontinuous open (3DBO) nanoporosity has been recognized as an important nanoarchitecture for catalysis, sensing, and energy storage. Dealloying, i.e., selectively removing a component from an alloy, is an efficient way to fabricate nanoporous materials. However, current electrochemical and liquid-metal dealloying methods can only be applied to a limited number of alloys and usually require an etching process with chemical waste. Here, we report a green and universal approach,…

Nature Communications · 2022-05-25 · 40 citations
articleOpen accessThe past few years have witnessed the rapid development of liquid metal dealloying to fabricate nano-/meso-scale porous and composite structures with ultra-high interfacial area for diverse materials applications. However, this method currently has two important limitations. First, it produces bicontinuous structures with high-genus topologies for a limited range of alloy compositions. Second, structures have a large ligament size due to substantial coarsening during dealloying at high temperatu…
