Realizing highly selective and efficient CH4 conversion to CH3OH HCHO can bring about both energy environmental benefits is of great significance for social development. Herein, an integrated Fe2O3/WO3 heterojunction was established used photooxidation at ambient temperature. Under optimized experimental conditions, a high + yield 15.3 mmol g–1 h–1 achieved with selectivity 97.3%, outperforming most the current reports so far as we know. This improved catalytic performance could be...
Reticular BiVO4 catalysts were successfully synthesized via a modified sol-gel method. Here, citric acid (CA) was used as the chelating agent and ethylenediaminetetraacetic (EDTA) template. Furthermore, effects of pH values EDTA on structure morphology samples studied. We determined that played important roles in determination as-prepared samples. Photocatalytic evaluation revealed reticular exhibited superior photocatalytic performance characteristics for degradation methylene blue (MB)...
Abstract The thermal conductivities of Nd:YAG, M(Y,Gd)VO 4 crystals were measured at 298 K. value Nd:GdVO crystal along <001> direction was 11.4 W/mK, which higher than that YAG to be 10.7 W/mK. principal refractive indices in the temperature range from 20 °C 170 determined by auto‐collimation method. Based on values indices, Sellmeier equation and expression dependence have been obtained. results show birefringence Δn is 0.22007 coefficient 4.33 × 10 −6 /°C for 1.064 μm. These prove...
Using a one‐step hydrothermal method and at different stirring speeds ( V s ), we have synthesized types of CoFe 2 O 4 ‐based magnetic nanocrystalline samples. With increasing , the sample changes from nanocomposite / Co 0.7 Fe 0.3 CFO CF ) to single‐phase ). The maximum magnetization, 88.9 emu/g, coercivity, 3010 Oe, were obtained when = 0. As increases, saturation magnetization M decreases, because amount soft phase decreases. A clear enhancement in remanence, r was observed, with 0.67;...
In this work, by taking commercial P25 hydrophilic titanium dioxide (TiO2) as a photocatalyst, the magnetic field effect (MFE) on photodegradation rate of methyl orange is studied. It found that relatively lower B = 0.28 T can efficiently enhance efficiency TiO2 24%. However, will be suppressed slightly 7% under 0.5 T. Moreover, such MFE photocatalyst dependent settling state reaction solution. Additional experiments degradation other pollutants (methylene blue) and with photocatalysts...
Efficiently converting methane (CH4) to C1 products such as CH3OH, HCHO, and CH3OOH is considered a promising route for the chemical industry, while huge challenge of low CH4 activation rate still remains. Here, Cu/ZnO composite catalyst with CuOx supported on ZnO synthesized modify electronic structure utilized conversion. The fast e– transfer channel → Cu O2 facilitates dissociation •OOH, which promotes charge separation and, in parallel, enables oxidation •CH3 by h+ left acceleration...
CeO 2 with abundant surface O v was prepared for direct CH 4 photocatalytic conversion. Both high C1 product yield and selectivity of 3.88 mmol (g cat h) −1 97.73% were obtained.

Dysprosium (Dy)‐doping SrMoO 4 (with different molar ratio of Dy/Sr = 0/100, 10/100, 15/100 and 20/100) have been synthesized by high temperature thermal decomposition metal–organic salt in organic solvent with a boiling point. Their structures, morphology, optical properties were characterized X‐ray diffraction (XRD), high‐resolution tuning electron microscopy ((HR)TEM), photo‐electron spectroscopy (XPS), UV–vis diffuse reflectance (UV–vis DRS). Using this method, the pure phase, nano‐size,...
An anatase/rutile (A/R) TiO 2 biphase junction was established and used for mostly improved CH 4 photocatalytic conversion, by combining enhanced carrier separation efficiency reduced C–H cleavage energy.
Controlling or eliminating the extrinsic interfacial effects is an important concern in studies of two-dimensional van der Waals (2D vdW) heterostructures. In this Letter, by using WSe2/BN as a model, annealing effect on elimination 2D vdW heterostructures was studied. The formation interface can generate defects and significantly regulate type peak intensity percentage WSe2 photoluminescence (PL) peak. It intriguing to find that thermal optical property opposite from defects. By optimizing...
