New MoO3 or WO3 modified CeO2-ZrO2 aerogel catalysts were elaborated using the sol gel method combined to supercritical drying for NO-SCR by NH3 in excess of O2. XRD, N2-Physisorption, NH3-TPD, H2-TPR and DRUV-Vis spectroscopy used analyse samples. The results reveal that all powders (ZrO2, CeO2-ZrO2, MoO3-ZrO2, WO3-ZrO2, MoO3-CeO2-ZrO2 WO3-CeO2-ZrO2), calcined at 500 °C, are nanostructured mes...

In this work, a novel Z-scheme heterojunction of ZIF67/WO3 nanocomposite is successfully prepared via immobilizing WO3 on the MOFs ZIF67 and confirmed by measuring XRD, FT-IR spectroscopy, XPS, SEM, TEM, EDS. UV–vis Mott-Schottky measurements. The photocatalytic activity as-prepared evaluated degrading methylene blue (MB) solution under simulated visible light irradiation. Obviously, optimal ZI...

The study reports preparation, characterization, and catalytic activity of Pd0/WO3 nanoparticles in H2 evolution from dimethylamine borane (DMAB). active catalyst called NPs were obtained the situ reduction Pd2+/WO3 precatalyst tested releasing DMAB. found as remarkable catalysts providing a turnover frequency value 948.0 h-1 DMAB at 60.0 ± 0.5 °C. results some advanced analytical techniques re...

The assembly of monomicelles along one-dimension (1D) to construct tubular or fibrous mesostructures is greatly desired but still challenging. Herein, we have demonstrated a facile strategy synthesize 1D bimodal mesoporous metal oxides (e.g., WO3, WO3/Pd, WO3/PdCu, TiO2, and ZrO2) nanofibers (NFs) through assembling the organic-inorganic composite in beam stream generated via an electrospinning...

in this work, hierarchical wo3 core-shell microspheres were synthesized via a facile template-free precipitation method. gas sensing properties of the synthesized powder to acetone and some other volatile organic compounds were comparatively investigated with commercial wo3 nanoparticles. the synthesized and commercial powders were characterized by x-ray diffraction, scanning electron microscop...

Hexagonal (h-WO3) mesocrystals with biconical morphology were prepared by a straightforward ionic liquid-assisted hydrothermal route and investigated as anodic materials for lithium-ion batteries. Compared to the alternatives, the biconical tungsten trioxide mesocrystal exhibited excellent lithium insertion with good cyclability and rate capability, making it a promising candidate as the anode ...
