Ma and his co-workers have now developed a mechanochemical method to mass produce SACs. They ground together dry starting materials – a technique known as ball milling – to make kilograms of evenly-dispersed SACs on a zinc oxide support. Palladium, rhodium, ruthenium and palladium–copper SACs were all produced using the ball-milling process. 'We estimate that with our strategy, the ...
