Abstract

A series of metal decorated hydrogenated TiO ₂ nanofibers (metal-H:TiO ₂ NFs) are synthesized successfully in this study. It is synthesized by the hydrothermal approach and combined with wet impregnation method in thermal hydrogen reduction. Nine types of metal nanoparticles, Ag, Co, Cr, Cu, Fe, Ni, Pd, Pt and Y, were used to decorate on the surface of H:TiO ₂ to enhance the photocatalytic activity. The photocatalytic performance of various metal-H:TiO ₂ NFs was estimated by the photodegradation of organic dyes. Ag-H:TiO ₂ NFs gives the fastest decoloration rate of brilliant green among others. Moreover, the evolution rate of H ₂ over Pd-H:TiO ₂ NFs under UV-A and UV-B illumination is 17,000 μmol/g·h and 25,600 μmol/g·h, respectively, which corresponding to photoefficiency values of ∼7.54% and ∼11.35%. The metal-H:TiO ₂ NFs developed in this study can be a facile and environmentally friendly way for searching the high-performance photocatalysts in the field of environmental and energy issue.
