Synthesis of TiO2 Nanotubes Decorated with Ag Nanoparticles (TNTs/AgNPs) For Visible Light Degradation of Methylene Blue

An improved photocatalytic activity of semiconductor materials using incorporation of the noble metals such as Ag, Au, and Pt is a promising technology. In this study, Ag nanoparticle-TiO2 nanotube structures (Ag-TNTs) have been investigated as a photocatalyst in different irradiation conditions using different characterization techniques. The results indicate that Ag nanoparticles dispersed uniformly on the TNTs’ surface without any change in TNTs’ morphology. In addition, Ag-TNTs exhibited lower photoactivity than the TNTs under UV irradiation. In contrast, Ag-TNTs increased the photoactivity in comparison with TNTs and the photocatalytic performance under sunlight irradiation. These phenomena could be contributed to the appearance of Ag nanoparticles on the nanotube surface.

Phase Synthesis

We have synthesized layered Ni(OH)2via a facile liquid-phase precipitation method. NiO with a micro/nano-structure was obtained via calcining Ni(OH)2precursor at 350°C. The as-prepared NiO was utilized as a support to load Ag nanocrystals. SEM and TEM observations showed that Ag nanoparticles were homogeneously distributed onto NiO support and the Ag nanoparticles have sizes of 4-5 nm. The photocatalytic activity of NiO-loaded Ag was investigated by the photodegradation of methylene blue (MB) under the irradiation of visible light. The results suggest that the loading of Ag nanoparticles can enhance the photo-degradation performance of pristine NiO.

Visible Light Photocatalytic

The synthesis of NdFeO3 perovskites in a reverse microemulsion and its photocatalytic property for visible light degradation reaction of methylene blue were investigated, respectively. When the irradiation time prolonged from o to 90 minutes, the degradation rate for methylene blue could achieve 60%. XRD pattern shows that a well-crystallized perovskite structure is observed for the NdFeO3 sampled prepared. The TEM characterization result indicates that the dimension of NdFeO3 nanopowders is in the range of 35~45 nm, which is consistent with the calculation result using the Scherrer equation.
