Researchers at Northwestern University have developed a new method to synthesize high-entropy alloy nanoparticles with controlled surface structures, enabling the discovery of next-generation catalysts. The breakthrough involves a three-component synthesis strategy and a high-throughput screening process.
Northwestern University researchers have made a breakthrough in synthesizing high-entropy alloy nanoparticles. These alloys, composed of five or more elements, have shown promise as catalysts due to their complex surfaces. The team, led by Chad A. Mirkin and Christopher M. Wolverton, developed a three-step strategy to control the surface structure of these nanoparticles. This involved combining target metals with liquid gallium, introducing a volatile metal, and then evaporating it to favor high-index facet formation. The researchers applied this method to megalibraries, a nanomaterial synthesis platform, to produce approximately 36 million nanoparticles across 90,000 unique compositions on a single chip. This high-throughput approach enables the screening and discovery of next-generation catalysts with high-index facets.
