Element doping has been extensively attempted to develop visible-light-driven photocatalysts, which introduces impurity levels and enhances light absorption. However, the dopants can also become recombination centers for photogenerated electrons holes. To address challenge, we report a gradient phosphorus-doped CdS (CdS-P) homojunction nanostructure, creating an oriented built-in electric-field efficient extraction of carriers from inside surface photocatalyst. The apparent quantum...
Hydrogenated {001}-facets-dominated anatase TiO2 nanosheets have O–H bonds and O− on their surface. The high reactive {001} facets were maintained by the formation of Ti–H bonds. A large number Ti3+ ions oxygen vacancies produced hydrogenation, resulting in improved light absorption enhanced photocatalytic activity.
Abstract A strategy has been adopted for simultaneous morphology manipulation and upconversion luminescence enhancement of β-NaYF 4 :Yb 3+ /Er microcrystals by simply tuning the KF dosage. X-ray power diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission (TEM), photoelectron spectroscopy (XPS) photoluminescence spectra (PL) were used to characterize samples. The influence molar ratio Y on crystal phase systematically investigated discussed. It is found that...
Double-shell-structured β-NaYF4:Yb3+,Tm3+/Er3+@SiO2@TiO2 upconversion photocatalysts have been successfully synthesized by a simple hydrothermal method. It is found that the double-shell-structured photocatalyst consists of uniform β-NaYF4:Yb3+,Tm3+/Er3+ nanocrystals, SiO2 as media shell, and anatase TiO2 nanocrystals exposed with high-reactive {001} facets outer shell. The shell modified to absorb both UV visible light in order make sufficient use upconverted from for photocatalysis....
Polyvinylidene fluoride (PVDF) and poly(methyl methacrylate) (PMMA) blend films were prepared using biaxial stretching. The effects of PMMA content stretching ratio on the crystallinity β phase fraction PVDF in investigated. distributions variable locations also studied. results FTIR XRD showed that appeared PVDF/PMMA blends after extrusion casting procedures. Although decreased preheating, there was still an increasing trend during following More importantly, increase improved fraction,...
Hexagonal sodium yttrium fluoride crystals with predictable shapes, such as microtubes, microspheres, microrods, micro-bipyramids, microplates, and microprisms, have been synthesized by simply tuning the molar ratio of NaF to RE3+ (RE represents total amount Y3+ doped rare earth elements Yb3+, Er3+). The structural kinetic factors that govern phase shape evolution NaYF4 carefully studied, influence on morphology was systematically investigated discussed. It is found can strongly control size...
Abstract Utilization of low‐energy photons for efficient photocatalysis remains a challenging pursuit. Herein, strategy is reported to boost the photocatalytic performance, by promoting dual harvest through bimodal surface plasmon resonance (SPR)‐enhanced synergistically upconversion and pyroelectricity. It achieved introducing triplet–triplet annihilation (TTA‐UC) materials plasmonic material (Au nanorods, AuNRs) into composite fibers composed pyroelectric substrate (poly(vinylidene...
Energy consumption during cooling and heating poses a great threat to the development of society. Thermal regulation, as switchable in single platform, is therefore urgently demanded. Herein, multifunctional device integrating heating, cooling, latent energy storage was proposed for temperature regulation window saving buildings. A radiative (RC) emitter, phase-change (PC) membrane, solar-heating (SH) film were connected layer by form sandwich structure. The RC emitter exhibited selective...
Graphene and ZnO as two star materials were united to constitute the photoanode of dye-sensitized solar cells (DSSCs). Highly electronically conductive graphene scaffolds incorporated into hierarchically structured nanoparticle (HSN) photoanodes could simultaneously capture transport photogenerated electrons injected by excited dyes. This strategy was beneficial for fluently transfer collection electrode due decreased internal resistance electron recombination loss. On basis these...
