Au-TiO2 composite photocatalysis material was fabricated by the photodeposition method. The SEM and TEM images demonstrate that Au-TiO2 NPs are with inerratic geometry and their diameters are in the range of 10 nm to 20 nm. The UV-vis spectra shows the strong peaks in 200-400 nm and near 550 nm which are attributed to the characteristic absorption peak of TiO2 and the strong surface-plasmon-resonance of Au NPs, respectively. Under visible light irradiation, the phenol degradation dynamics constant on Au-TiO2 was 0.008 min-1 which was 4 times of that on Degussa P25. The effects of Au amount on the photocatalytic capability of Au-TiO2 were also investigated.

Gold nanoparticles show important electronic and optical properties, owing to their size, shape, and electronic structures. Indeed, gold nanoparticles containing no more than 30–40 atoms are only luminescent, while nanometer-sized gold nanoparticles only show surface plasmon resonance. Therefore, it appears that gold nanoparticles can alternatively be luminescent or plasmonic and this represents a severe restriction for their use as optical material. The aim of our study was the fabrication of nanoscale assembly of Au nanoparticles with bi-functional porphyrin molecules that work as bridges between different gold nanoparticles. This functional architecture not only exhibits a strong surface plasmon, due to the Au nanoparticles, but also a strong luminescence signal due to porphyrin molecules, thus, behaving as an artificial organized plasmonic and fluorescent network. Mutual Au nanoparticles–porphyrin interactions tune the Au network size whose dimension can easily be read out, being the position of the surface plasmon resonance strongly indicative of this size. The present system can be used for all the applications requiring plasmonic and luminescent emitters.

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.
