Abstract

C shells: A facile and versatile synthesis using dopamine as a carbon source gives hollow carbon spheres and yolk-shell Au@Carbon nanocomposites (see pictures). The uniform nature of dopamine coatings and their high carbon yield endow the products with high structural integrity. The Au@C nanocomposites are catalytically active.
