Hollow alloy: Vesicles formed from tetrabutylammonium bromide and metal compounds act as efficient directors for the rapid synthesis of a variety of binary, ternary, and quaternary intermetallic materials with hollow structures. In this way, different metals were co-alloyed on the vesicle surface to produce hollow alloy spheres containing more than two kinds of metals.
