Description
Summary:In this letter, we have demonstrated that gold nanostructures could be selectively deposited on electrospun titania nanofibers through the photocatalytic reduction of HAuCl 4 in the presence of an organic capping reagent. Depending on the type and concentration of capping reagent used, gold nanoparticles, fractal nanosheets or nanowires could be obtained. This approach provides a simple route to fabricate metal-decorated titania nanofibers that hold much promise for use in catalysis and chemical sensing.
