Abstract
In this work, we proposed a simple method to synthesize gold nanoparticles carried by boehmite, which was made directly from Al/Au bilayer films by a one-step hydrothermal treatment. The boehmite carrier is porous with a special density-gradient structure. As a result, the embedded gold nanoparticles demonstrate good size uniformity, strong surface plasmon resonance, and good affinity for reacting solution. Such nanoparticles carried by boehmite exhibit the high potential of applications as efficient catalysts and sensitive bio-sensors.
