Noble metals, widely used as catalyst components, are expensive and of limited supply. Thus, enormous efforts have been devoted to reducing the consumption of noble metals. In principle, the CASs of supported noble metal catalysts are either the perimeter atoms of metal NPs in contact with supports or exposed surface atoms of metal NPs [13–15], whereas the metal atoms inside NPs are not involved in catalysis. Thus, constructing SACs is effective for making full use of metal atoms.
