“…The thickness of fiber shell is ∼40 nm, as determined by TEM. , In addition, the X-ray diffraction (XRD) pattern of nanofibers obtained by electrospinning is provided in Figure F, and reveals strong diffraction peaks at 25, 38, and 48°. This result indicates that the TiO 2 is in the anatase phase. , Furthermore, this novel structure can be validated by SEM images along the radial and axial directions (cut by FIB). These images present an excellent juncture between the outer-shell and inner-continuous TiO 2 , reconfirming the absence of the PS-rich phase in neighboring layer of gyroid in fibers prior to calcination (Figure S3).…”

By coupling the self-assembly of polystyrene-block-poly(ethylene oxide) (PS-b-PEO) containing titanium precursors with the electrospinning technique, novel cigarlike nanofibers with an outer-shell and inner-continuous-pore structure and resultant fabrics were fabricated. Different from typical porous metal oxides, the prepared high-surface-area nonwoven fabrics show excellent mechanical properties. Not only are these fabrics self-supporting over a large area, but they can also be cut using scissors, which is important for large-scale applications. Furthermore, as electrode materials in Li-ion batteries, these fabrics exhibit much higher charge/ discharge capacity and cycle stability compared with the commercially available nanosized TiO 2 (P25). The improved mechanical and electrochemical performances are attributed to the presence of an outer-shell, inner-bicontinuous structures (including continuous TiO 2 frame and continuous nanopores) and hierarchical pores from the cigarlike nanofibers.

“…The incident light can interact with Au-decorated TiO 2 nanowire electrodes in three different ways: (1) reflected by the electrode; (2) absorbed by TiO 2 nanowires, and (3) excited surface plasmons of Au . In the first case, incident light will, in general, be partially reflected upon the electrode surface because of the high refractive index of rutile TiO 2 (RI = 2.7). , The decorated Au can, however, scatter the reflected light back to TiO 2 to improve the overall photon harvesting efficiency. Nevertheless, we suggest that the contribution from light scattering of Au was relatively insignificant considering that the percentage of the decorating Au was rather low (<3.0 wt %).…”

Au Nanostructure-Decorated TiO₂ Nanowires Exhibiting Photoactivity Across Entire UV-visible Region for Photoelectrochemical Water Splitting

Here we demonstrate that the photoactivity of Au-decorated TiO2 electrodes for photoelectrochemical water oxidation can be effectively enhanced in the entire UV-visible region from 300 to 800 nm by manipulating the shape of the decorated Au nanostructures. The samples were prepared by carefully depositing Au nanoparticles (NPs), Au nanorods (NRs), and a mixture of Au NPs and NRs on the surface of TiO2 nanowire arrays. As compared with bare TiO2, Au NP-decorated TiO2 nanowire electrodes exhibited significantly enhanced photoactivity in both the UV and visible regions. For Au NR-decorated TiO2 electrodes, the photoactivity enhancement was, however, observed in the visible region only, with the largest photocurrent generation achieved at 710 nm. Significantly, TiO2 nanowires deposited with a mixture of Au NPs and NRs showed enhanced photoactivity in the entire UV-visible region. Monochromatic incident photon-to-electron conversion efficiency measurements indicated that excitation of surface plasmon resonance of Au is responsible for the enhanced photoactivity of Au nanostructure-decorated TiO2 nanowires. Photovoltage experiment showed that the enhanced photoactivity of Au NP-decorated TiO2 in the UV region was attributable to the effective surface passivation of Au NPs. Furthermore, 3D finite-difference time domain simulation was performed to investigate the electrical field amplification at the interface between Au nanostructures and TiO2 upon SPR excitation. The results suggested that the enhanced photoactivity of Au NP-decorated TiO2 in the UV region was partially due to the increased optical absorption of TiO2 associated with SPR electrical field amplification. The current study could provide a new paradigm for designing plasmonic metal/semiconductor composite systems to effectively harvest the entire UV-visible light for solar fuel production.
