In this work, we report for the first time on the use of melt spun glass-forming alloysTi 75 Zr 10 Si 15 (TZS) and Ti 60 Zr 10 Si 15 Nb 15 (TZSN) -as substrates for the growth of anodic oxide nanotube layers. Upon their anodization in ethylene glycol based electrolytes, highly ordered nanotube layers were achieved. In comparison to TiO 2 nanotube layers grown on Ti foils, under the same conditions for reference, smaller diameter nanotubes (~116 nm for TZS and ~90 nm for TZSN) and shorter nanotubes (~11.5 µm and ~6.5 µm for TZS and TZSN, respectively) were obtained for both amorphous alloys. Furthermore, TEM and STEM studies, coupled with EDX analysis, revealed a double-wall structure of the as-grown amorphous oxide nanotubes with Ti species being enriched in the inner wall, and Si species in the outer wall, whereby Zr and Nb species were homogeneously distributed.

“…26 The fcc diffraction pattern of gold structures is difficult to visualize in crystalized TiO 2 , since its intensity is very low due to the inherent nanometric size and low concentration compared with TiO 2 structures. Additionally, the major diffraction peaks of the fcc gold structure match those from crystalline TiO 2 phases.…”

Um novo método para a fabricação de nanotubos (NTs) de TiO 2 organizados e impregnados com nanopartículas (NPs) de ouro foi desenvolvido, e as propriedades estruturais, morfológicas e ópticas dos NTs obtidos foram investigadas. Os arranjos de NTs de TiO 2 foram crescidos pela oxidação anódica de Ti metálico utilizando soluções eletrolíticas contendo íons fluoreto e NPs de Au. As estruturas resultantes foram caracterizadas por espectrometria de retroespalhamento Rutherford (RBS), difratometria de raios X com incidência rasante (GIXRD), microscopias eletrônicas de transmissão (TEM) e de varredura (SEM) e espectroscopia UV-Vis. Tanto os arranjos de NTs sem Au quanto os impregnados com Au mostraram atividade fotocatalítica boa e estável na geração de hidrogênio a partir de misturas água/metanol. Os nanotubos de TiO 2 contendo Au foram mais ativos na fotogeração de hidrogênio do que os NTs de TiO 2 sem Au.A novel method for the fabrication of TiO 2 nanotubes (NTs) impregnated with gold nanoparticles (NPs) is reported. TiO 2 NT arrays were grown by anodic oxidation of Ti metal using fluoride electrolytes containing Au NPs. Resulting structures were characterized by Rutherford backscattering spectrometry (RBS), grazing incidence X-ray diffractometry (GIXRD), transmission and scanning electron microscopy (SEM and TEM) and UV-Vis spectroscopy. Au-free and Au-impregnated TiO 2 NT arrays showed good and stable photocatalytic activity for hydrogen generation from water/methanol solutions. Au-containing TiO 2 NTs presented higher hydrogen photogeneration activity than Au-free TiO 2 NTs.
