Figure 1. Synthesis and characterization of Al@TiO2.

Figure 1

(a) Schematic of the ‘in situ water-shift’ synthesis of Al@TiO2. The colours represent chemical contents in the solution: the equilibrated mixture of H2SO4 and TiOSO4 is light yellow, H2O is blue, and H2SO4 is green. (b) X-ray diffraction data of commercial nano aluminium powder and the as-obtained Al@TiO2 with 4.5 h etching. The original Al2O3 layer is completely eliminated after our experimental procedure and the final product consists of pure metallic aluminum and anatase.
