The present review on some metal oxide nanoparticles used for pressure sensor, various metal oxide containing such as (SnO2, ZnO, Al2O3, WO3, Fe2O3, Ga2O3, TiO2 and SiC, ...etc.) responds detection pressure measure in kbar unit through oxygen activity as oxidation or reduction process of an integrated in devices sensor (MEMS, CMOS, MOX and MOXQ1D...etc.) that devices measuring of pressure as st...

The motivation of using metal oxides is mainly due to its charge storage capabilities, and electrocatalytic, electrochromic and photoelectrochemical properties. But comparing with bulk, nanostructured materials present several advantages related with the spatial confinement, large fraction of surface atoms, high surface energy, strong surface adsorp‐ tion and increased surface to volume ratio, ...

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...

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 photocatalytic proprieties of TiO2/FeO3 and TiO2/WO3 nanocomposites have been investigated using methylene blue as a pollutant. We propose non-conventional approach for material preparation, i.e., the Doctor Blade technique, which is an easy inexpensive method coating materials. Several drawbacks related to use powders can be alleviated by solid substrates, this deposition allows us take ad...

Hydrogen (H2) is a renewable energy source that has the potential to reduce greenhouse gas emissions. However, H2 also highly flammable and explosive, requiring sensitive safe sensors for its detection. This work presents synthesis characterization of WO3/graphene binary WO3/graphene/Pd (WG-Pd) ternary nanocomposites with varying graphene Pd contents using microwave-assisted hydrothermal method...

Visible light-sensitive photocatalyst was developed by combining n-type silicon (n-Si) and tungsten trioxide (WO3, n-Si/WO3), yielding an ohmic contact in between. In this system, the ohmic contact acted as an electron-and-hole mediator for the transfer of electrons and holes in the conduction band (CB) of WO3 and in the valence band (VB) of n-Si, respectively. Utilizing thusconstructed n-Si/WO...
