The performances of heterojunction-based electronic devices are extremely sensitive to the interfacial band structure. Here we report a largely enhanced performance photoelectrochemical (PEC) photoanodes by ferroelectric polarization-endowed engineering on basis TiO2/BaTiO3 core/shell nanowires (NWs). Through one-step hydrothermal process, uniform, epitaxial, and spontaneously poled barium titanate (BTO) layer was created single crystalline TiO2 NWs. Compared pristine NWs, 5 nm BTO-coated...
Efficient charge separation and transportation are key factors that determine the photoelectrochemical (PEC) water‐splitting efficiency. Here, a simultaneous enhancement of hole on basis ferroelectric polarization in TiO 2 –SrTiO 3 core–shell nanowires (NWs) is reported. The SrTiO shell with controllable thicknesses generates considerable spontaneous polarization, which effectively tunes electrical band bending . Combined its intrinsically high mobility, thin significantly improves...
Anatase TiO(2) nanosheets-based hierarchical spheres with over 90% {001} facets synthesized via a diethylene glycol-solvothermal route were used as photoanodes of dye-sensitized solar cells, which generated an energy conversion efficiency 7.51%.
In this study, well-crystallized mesoporous anatase TiO2 spheres were prepared by hydrothermal treatment of the titanium diglycolate precursors. These are submicrometer-sized and consist packed nanocrystallites with diameters ∼8 nm, possess a specific surface area 193 m2 g−1 main pore sizes ∼5 nm. We demonstrated that due to large particle ultrahigh areas, microspheres can enhance light harvesting within photoanodes for dye-sensitized solar cells (DSSCs), meanwhile, their good crystallinity...
Surface plasmonic resonance (SPR) is a new paradigm in photoelectrochemical (PEC) research that realizes the persistent supply of green energy sustainable manner. However, typical approaches for decorating surfaces Au nanoparticles (NPs), such as colloidal chemical method, nanolithography, and situ photo/thermal reduction, involve multiple complex steps often introduce unwanted surface/interface chemicals jeopardize SPR effect charge transport. Herein, we report largely enhanced PEC...

The effective separation and efficient transportation of photogenerated carriers within a photoanode are critical factors for achieving outstanding photoelectrochemical (PEC) water splitting. In this study, TiO2-ferrihydrite (Fh)-MXene nanowire arrays (NWAs) fabricated by hydrothermal method followed spin coating. TiO2-Fh-MXene NWAs achieved photocurrent density 1.44 mA/cm2 at 1.23 V versus the reversible hydrogen electrode (vs RHE), surpassing TiO2-Fh 2.05 times TiO2 2.93 times. According...
The rutile TiO2 nanorods (RTNs) with the length of 40–130 nm and diameters approximately 8–15 nm, containing some 300–500 sized RTN aggregates 6% anatase nanocrystals, were prepared by surfactant-assisted hydrothermal method. dye-sensitized solar cell (DSC) based on RTNs exhibited power conversion efficiency 6.03%. As compared to P25 DSC, DSC shows improved light-harvesting Brunauer–Emmett–Teller surface area, leading an increase in short-circuit current (Jsc) 40.6%.
A facile one-step synthesis process to fabricate single-crystal anatase TiO2 tetragonal faceted-nanorods (ATTFNRs) is introduced through using tetrabutylammonium hydroxide (TBAH) as a morphology controlling agent. The obtained ATTFNRs are dominated by large percentage of {010} facets. formation mechanism the proposed. power conversion efficiency dye-sensitized solar cell (DSSC) based on (7.73%) exhibits significant improvement (37%) compared that nanoparticles (5.65%). improved performance...
High light absorption capability and excellent charge carrier kinetics play a key role in determining the improved photoelectrochemical (PEC) performance. Here, to extend photoresponse of TiO2 visible-light range, we encapsulated narrow band gap CoTiO3 on surface nanowire arrays (NWAs) form core–shell heterostructure. The shell thickness can be controlled by hydrothermal reaction time. TiO2/CoTiO3 NWAs with 9.7 nm had highest Jph (0.95 mA/cm2 at 1.23 V versus RHE) largest concentration (1.53...
Abstract Atomically thick two‐dimensional transition metal dichalcogenides (TMDs) have been extensively studied as optoelectronic materials because of their distinctive electronic structures and outstanding photonic catalytic properties. In particular, when the size TMDs are decreased to quantum scale, they possess wider bandgaps higher surface‐to‐volume ratios with more active edge sites per unit mass. Hence, promising for use in sensor, battery, electrocatalytic applications. this study,...
