Tungsten trioxide (WO3) nanorods with an aspect ratio of ∼50 have been successfully synthesized by hydrothermal reaction at a low temperature 100 °C. The crystal structure, morphology evolution and thermal stability the products are characterized in detail XRD, FESEM, FTIR, TG/DTA techniques. diameter distribution WO3 strongly depend on time. Hydrothermal conditions °C 24 h ensure formation well-defined nanorods. transition structure from monoclinic to hexagonal occurs after calcination 400...
Nanosheet-assembled tungsten oxide microspheres have been synthesized using rapid sonochemistry followed by thermal treatment. Transient observation of controllable synthesis reveals that the morphological evolution product is highly dependent on ultrasonication time. An assembly mechanism based oriented attachment and reconstruction proposed for sonochemical formation nanosheet-assembled microspheres. The obtained samples possess intrinsic non-stoichiometry a hierarchically porous...
Quantum-sized ZnO nanoparticles have been synthesized at room temperature by a mild sol–gel process using tetraethylorthosilicate (TEOS) as the capping agent to control particle growth of ZnO. The crystal structure, size and optical properties investigated X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), photoluminescence (PL) spectra Raman spectra, respectively. results show that exhibit hexagonal wurtzite structure average crystallite is 5.7 nm which...
Al-doped flower-like ZnO nanostructures have been synthesized by a facile hydrothermal method at 95 °C for 7 h. The structure and morphology of the product were characterized XRD, FTIR SEM analysis. sensing tests reveal that response is significantly enhanced Al doping, 0.3 wt% sample exhibits highest 464 to 10 ppm CO an operating temperature 155 °C. A change structural defects in responsible enhancement properties, which has confirmed room photoluminescence (PL) spectra X-ray photoelectron...

The not only exhibits high sensitivity, good selectivity and fast response but also has flexibility, inexpensive wearable characteristics.
Combining semiconductor heterojunction and cocatalyst is an important strategy to improve photoelectrochemical (PEC) water splitting efficiency. Here, a photoanode of WO3/Fe2O3 decorated by NiFe-layered double hydroxide (LDH) was fabricated two-step hydrothermal methods. As expected, the photocurrent density ternary reaches up 3.0 mA·cm–2, which respectively are 5 times 7 WO3 α-Fe2O3. The improvement benefits from extending absorption visible light, effective separation photogenerated charge...
A Cu2O/BiVO4 p-n heterojunction based photoanode in photoelectrochemical (PEC) water splitting is fabricated by a two-step electrodeposition method on an FTO substrate followed annealing treatment. The structures and properties of the samples are characterized XRD, FESEM, HRTEM, XPS UV-visible spectra. activity oxidation has been investigated measured three electrode quartz cell system; obtained maximum photocurrent density 1.72 mA cm-2 at 1.23 V vs. RHE 4.5 times higher than that pristine...
