Materials that speed up a chemical reaction without getting consumed in the process, known as catalysts, lie at the heart of many technologies, from vehicle emissions-control systems to high-tech devices such as fuel cells and electrolyzers. Unfortunately, catalysts are often pricey because they typically contain one or more noble metals, such as platinum or palladium, whose supplies are limited.
