0D/1D CuWO/MnCdS S-scheme heterojunctions for full-spectrum bifunctional photocatalytic degradation and hydrogen production.

Integrating photocatalytic oxidation for pollutant removal with hydrogen production via photocatalysis presents a promising approach for sustainable water purification and renewable energy generation, circumventing the sluggish multi-electron transfer inherent in photocatalytic water oxidation. This study introduces novel zero-/one-dimensional (0D/1D) CuWO/MnCdS step-scheme (S-scheme) heterojunctions that exhibit exceptional bifunctional capabilities in photocatalytic degradation and hydrogen production under full-spectrum illumination. The degradation efficiency for tetracycline (TC) using 5 %-CuWO/MnCdS reaches 94.

Isomerization of surface functionalized SWCNTs and the critical influence on photoluminescence: static calculations and excited-state dynamics simulations.

Single-walled carbon nanotubes (SWCNTs) functionalized with sparse surface chemical groups are promising for a variety of optical applications such as quantum information and bio-imaging. However, the luminescence efficiencies and stability, two key aspects, undoubtedly govern their practical usage. Herein, we assess the surface migration of oxygen and triazine groups on as-modified SWCNT fragments by adopting transition state theory and explore the de-excitation of oxygen-functionalized SWCNT fragments by performing non-adiabatic excited-state dynamics simulations.

Bimetallic sulfide/N-doped carbon composite derived from Prussian blue analogues/cellulose nanofibers film toward enhanced oxygen evolution reaction.

Exploiting effective, stable, and cost-efficient electrocatalysts for the water oxidation reaction is highly desirable for renewable energy conversion techniques. Constructional design and compositional manipulation are widely used approaches to efficaciously boost the electrocatalytic performance. Herein, we designed a NiFe-bimetallic sulfide/N-doped carbon composite a two-step thermal treatment of Prussian blue analogues/cellulose nanofibers (PBA/CNFs) film.

Efficient wide-spectrum one-dimensional MWO (M = Mn, Co, and Cd) photocatalysts: Synthesis, characterization and density functional theory study.

Broadening the absorption region to near-infrared (NIR) light is critical for the photocatalysis due to the larger proportion and stronger penetration of NIR light in solar energy. In the present paper, one-dimensional (1D) MWO (M = Mn, Co, and Cd) materials synthesized by electrospinning technique, were studied by combining the density functional theory (DFT) with experiment results, which possessed the enhanced light absorption capability within the range of 200-2000 nm. It was proved that in the ultraviolet-visible (UV-Vis) region, the absorption bands of CoWO and MnWO samples were attributed to the metal-to-metal charge transfer mechanism, while the absorption of CdWO sample may be referable to the ligand-to-metal charge transfer mechanism.

High-Temperature Liquid-Liquid Phase Transition in Glass-Forming Liquid PdNiCuP.

Liquid-liquid phase transition (LLPT) is a transition from one liquid state to another with the same composition but distinct structural change, which provides an opportunity to explore the relationships between structural transformation and thermodynamic/kinetic anomalies. Herein the abnormal endothermic LLPT in PdNiCuP glass-forming liquid was verified and studied by flash differential scanning calorimetry (FDSC) and ab initio molecular dynamics (AIMD) simulations. The results show that the change of the atomic local structure of the atoms around the Cu-P bond leads to the change in the number of specific clusters <0 2 8 0> and <1 2 5 3>, which leads to the change in the liquid structure.

Co-Doped NiVO Nanofibers Achieving d-d Orbital Coupling for Electrocatalytic Oxygen Reduction.

Efficient and robust non-platinum-group metal electrocatalysts for O reduction are a prerequisite for practical high-performance fuel cells and metal-air batteries. Herein, we reported an integrated principle of gradient electrospinning and controllable pyrolysis to fabricate various Co-doped NiVO nanofibers with high oxygen reduction reaction (ORR) activity. The representative CoNiVO nanofibers showed outstanding ORR performance in an alkaline solution with a half-wave potential () of 0.

The intentional design and construction of photocatalysts containing heterojunctions with readily accessible active sites will improve their ability to degrade pollutants. Herein, hierarchically porous WO/CdWO fiber-in-tube nanostructures with three accessible surfaces (surface of core fiber and inner and outer surfaces of the porous tube shell) were fabricated by an electrospinning method. This WO/CdWO heterostructure, assembled by interconnected nanoparticles, displays good photocatalytic degradation of ciprofloxacin (CIP, 93.

Electrospun Mesoporous InVO /TiO Nanobelts with Enhanced Photocatalytic Properties.

In the present paper, mesoporous InVO /TiO nanobelts with diameter about 400 nm have been synthesized by elaborately designed electrospinning process. The microstructures of InVO /TiO nanobelts are characterized in detail, and their photoelectrocatalytic properties are comprehensively investigated by the photocatalytic degradation tests with tetracycline (TTC) and rhodamine B (RhB) waste water. Furthermore, the energy bandgap and density of states of orthorhombic InVO and anatase TiO are modeled and analyzed by density functional theory.

Facile Electrospinning of CeO2 /Bi2 WO6 Heterostructured Nanofibers with Excellent Visible-light-driven Photocatalytic Performance.

One-dimensional (1D) CeO2 /Bi2 WO6 heterostructured nanofibers with a diameter of about 300 nm were successfully synthesized by using a straightforward strategy combining an electrospinning technique with a sintering process. The acquired products were characterized by thermogravimetric and differential scanning calorimetric (TG-DSC), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area measurements, and UV/Vis spectroscopy. The obtained CeO2 /Bi2 WO6 heterostructured nanofibers exhibited an excellent photocatalytic property for the degradation of Rhodamine B (RhB) dye driven by visible light due to the promoted separation of photoelectrons and holes and the large contact area between the photocatalyst and organic pollutant.
