Grinding out single-atom catalysts made simple by ball mill

A new mechanochemical technique produces large batches of single-atom catalysts (SACs), without compromising on quality. Single-atom catalysis is a rapidly emerging field, offering deeper insight and unprecedented control over catalytic processes. SACs are generally formed of metal atoms dispersed across the surface of a support material. But scientists can usually only make a few grams or even milligrams of them at a time. Now, a new method based on ball-milling allows transition metal SACs to be made by the kilogram.
