Herein, by using buffer solution as a specific reaction We have paid special interest to the construction of medium, we demonstrate the possibility to grow thin nano- a uniform nanoshell of Al O , which is an important metal 2 3 shells of metal oxides, typically Al O , on different kinds of oxide and has a wide range of applications, e.g., in catal- 2 3 core materials, forming a uniform surface-coating layer with ysis,[1a, 6f] optics,[6d] and energy conversion and storage.[7] thicknesses achieving one nanometer precision.
