Cubic-shape hematite (C-Fe2O3) was facilely prepared by hydrothermal autoclave reaction of Fe3+ in the presence of 1,12-diaminododecane at 130 °C for 10 h. The surface of C-Fe2O3 was decorated with nanosilvers through the sonochemical reduction of Ag precursor (0.1-0.4 ml of 1.0 wt.% AgNO3), so-call...
