Cocatalysts-free SrTiO<sub>3</sub> nanofibers with high photocatalytic performance are developed by incorporating oxygen vacancies (OVs), where OVs could steer charge behaviors, serve as active sites and heighten reduction ability of electrons.
Enhanced activity in photocatalytic hydrogen generation is achieved with synergistic effects homogeneous n/n junctioned graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>).
Abstract Long afterglow materials can store and release light energy after illumination. A brick‐like, micrometer‐sized Sr 2 MgSi O 7 :Eu 2+ ,Dy 3+ long‐afterglow material is used for hydrogen production by the photocatalytic reforming of methanol under round‐the‐clock conditions first time, achieving a solar‐to‐hydrogen (STH) conversion efficiency 5.18 %. This one most efficient photocatalysts provides possibility practical use on large scale. Its remarkable activity attributed to its...
Abstract In the photothermal synergistic catalytic conversion of CO 2 and H O, catalyst harnesses solar energy to accumulate heat, thereby elevating reaction system’s temperature. The influence this temperature effect on surface chemical reactions remains an underexplored area. Here impact surface-level thermodynamic with O oxide semiconductors at atomic scale was investigated using first-principle calculations. 13 different metal oxides 5 transition clusters were used introduce functional...
Composites of titanium dioxide–reduced graphene oxide (TiO2–RGO) have been prepared via an efficient and facile hydrothermal reaction Ti(OH)4 in a ethanol–water solvent. The structure composition the composites characterized by X-ray diffraction, Scanning electron microscopy, Brunauer–Emmett–Teller specific area analysis, photoelectron spectroscopy ultraviolet-visible diffuse reflectance spectroscopy. results showed that TiO2–RGO exhibited layered with well-dispersed anatase TiO2 on surface...
The biocontrol agent Lysobacter enzymogenes produces polycyclic tetramate macrolactams (PoTeMs), including the antifungal HSAF. To elucidate biosynthesis of cyclic systems, we identified eleven HSAF precursors/analogues with zero, one, two, or three rings through heterologous expression gene cluster. A series combinatorial and deletion experiments showed that OX3 is "gatekeeper" responsible for formation first 5-membered ring from lysobacterene A, OX1 OX2 are second but different...
Function-switchable metal-free catalyst splits water to produce hydrogen in the absence of air, while peroxide is generated preferentially air.
Oxygen vacancies (OVs) on specific sites/facets can strengthen the interaction between reactants and oxide surfaces, facilitating interfacial charge transfer. However, precise monitoring of spatial distribution OVs remains a grand challenge. We report here that single-particle spectroscopy technique addresses this challenge by establishing positive correlation relationship defects bound exciton luminescence across different facets. Taking monoclinic BiVO4 as an example, basis theoretical...
In the marine environment, steel materials usually encounter serious problems with chemical or electrochemical corrosion and fouling by proteins, bacteria, other organisms. this work, a green bifunctional Z-scheme CuOx/Ag/P25 heterostructure coating material was designed to achieve coordination of prevention antifouling matching redox potential reactive oxygen species 304SS. When coupled protected metal, open circuit under illumination negatively shifted about 240 mV (vs. Ag/AgCl)...
Titanium dioxide (TiO2) has been long regarded as one of the more promising photocatalysts to remove environmental pollution and generate hydrogen from water under sunlight irradiation via photocatalysis. TiO2 is environmentally benign thus considered a 'green' catalyst. In this review we present short introduction physical electronic properties TiO2, its photocatalytic mechanisms, some recent examples various materials used for photocatalysis; these include 0, 1, 2, 3D, faceted, defected,...
The AlGaN/GaN heterostructure FETs with different gate lengths were fabricated. Under biases or for the devices lengths, measured parasitic source access resistance values different. By analysis of scattering mechanisms and polarization charge distribution, it is found that bias length can change Coulomb field scattering, then affect resistance. At last, systematic theories adopted influence on was further confirmed in theory.
Strontium Titanate has a typical perovskite structure with advantages of low cost and photochemical stability. However, the wide bandgap rapid recombination electrons holes limited its application in photocatalysis.
