“…No Ti 2+ peak related to titanium hydride phases (TiH 2Àx , x # 0.5) was observed in the Ti 2p XPS spectra, verifying that the TiH 1.5 phase was only formed at the Ti substrate. 34,38 The O 1s core level XPS spectra of anatase TiO 2 NTs and black TiO 2Àx NTs are shown in Fig. 1h.…”

“…† Emissions are observed close to the Fermi level, suggesting that these materials are semimetals or narrow bandgap semiconductors ( Fig. 13 The lowering of binding energy with hydrogenation in these emissions is likely related to the removal of alkyl groups from the structure, although specic assignments in a nonstoichiometric amorphous material are oen difficult.

“…Hydrogenation increases the emission at lower binding energy, and in the case of B100-H 2 , creates a new emission at 454.5 eV and 458.9 eV, also corresponding to Ti(III). 13 The lowering of binding energy with hydrogenation in these emissions is likely related to the removal of alkyl groups from the structure, although specic assignments in a nonstoichiometric amorphous material are oen difficult.

Titanium(III) hydrazide gels designed for Kubas-type hydrogen storage were synthesized from the reaction between tris(bis(trimethylsilyl)methyl) titanium and anhydrous hydrazine. The materials demonstrate a fully reversible H 2 adsorption capacity of 2.63 wt% and 36.7 kg m À3 at 298 K and 143 bar without saturation. Interaction between the adsorption center and H 2 gas was probed by electron paramagnetic resonance. † Electronic supplementary information (ESI) available: X-ray powder diffraction, elemental analysis tables, simulated X-ray photoelectron spectra for titanium and nitrogen, hydrogen adsorption isotherms at 77 K and 298 K for non-hydrogenated samples, infrared red spectra of titanium hydrazide materials and the LiCH(SiMe 3 ) 2 precursor, Ti{CH(SiMe 3 ) 2 } 3 , EPR of Ti hydrazide materials (A100-H 2 ) under Ar or H 2 .

“…For the NS interface ( Figure 3c and 3d ), the profiles after the first 4 minutes of etching indicated that Ti was the major phase, as evidenced by the normalized Ti 0 peak (Ti 2p3/2 = 454.1 eV, Ti 2p1/2 = 460.1 eV) 30 with a tiny amount of O belonging to lattice oxygen atoms and organic solvents (O 1s = 531.3 eV-531.6 eV, 533.7 eV). This is due to the treatment with methyl alcohol, which resulted in spontaneous disintegration of the anodized TiO 2 layer from the Ti substrate, leaving the NS surface mainly composed of Ti.…”

Gradient Control of the Adhesive Force between Ti/TiO2 Nanotubular Arrays Fabricated by Anodization

The poor control of the adhesion of TiO2 nanotubes (TNTs) layers to a non-anodized titanium (Ti) substrate has limited their widespread application, because the stripping mechanism has not yet been revealed. Here, we report a novel method to control the detachment of TNTs by post-treatment of the as-fabricated samples in protic and aprotic solvents with different polarities. Post-treatment using an organic solvent of lower polarity increases the adhesion of the tube layer, in contrast to the spontaneous detachment of the TNT layer after treatment using a solvent of higher polarity. The structure and the composition at the rupture interface were studied to explore the mechanism of the stripping behavior. Based on our experimental results and previous studies, a hypothesis of a hydrogen-assisted cracking (HAC) mechanism was proposed to explain the mechanism of TNTs' natural detachment and the control over of TNTs' stripping behaviors by post-treatment, in which the presence of protons at the interface between the TNT layer and the Ti substrate play an important role in controlling the two layers' cohesion. In summary, this method and mechanism hold promise to be used as a tool for the design and fabrication of TNT-related materials in future.
