Novel heterojunctions associating graphitic carbon nitride g-C3N4 and S-doped TiO2 nanoparticles were successfully designed prepared via a hydrothermal method used for photocatalytic degradations. The loading in S-TiO2 on was varied (5, 10 20 wt%), the photocatalysts characterized by XRD, FT-IR, solid-state UV-visible diffuse reflectance, photoluminescence, XPS, TEM SEM. (5%)/g-C3N4 catalyst exhibits highest activity degradation of methylene blue (MB) dye under visible light irradiation....
Aluminium-doped (3%) zinc oxide thin films (AZO) were prepared, using pulsed laser deposition, with varying deposition times. The target was fabricated from compacted aluminium-doped nano-powder produced by sol–gel. had a growth consisting of nanostructures in the form columns sharp ends which, for certain times, resemble nano-flowers or nano-leaves. small spheroid-like particles created during columnar act as seed other AZO needles, resulting appearance lotus-like flowers and even smaller...
(a) Shape of TiO 2 sample, (b) photoconductivity experimental set-up.
The annealing temperature (<italic>T</italic><sub>a</sub>) dependence of the structural, morphological, electrical and dielectric properties ZnS thin films was investigated.
In this work, the optical properties of tetra(imidazole) palladium phthalocyanine (PdPc(Im)4) in solution form and thin films on glass fluorine-doped tin oxide (FTO) substrates were investigated via thermal evaporation technique. The band gap was evaluated by ultraviolet-visible spectroscopy (UV-Vis). energy values determined based Tauc graph. addition, time-dependent density functional theory (TD-DFT) used to simulate UV-Vis absorption spectrum molecule Dimethyl Sulfoxide (DMSO) phase. A...

This work reports on the integration of ZnO pellets for use as a virtual sensor array (VSA) volatile organic compounds (VOCs).
Ozone detection is currently the subject of wide scientific and technological research, motivated by its harmful impact on human safety, environment health.
High-performance hydrogen sulfide (H2S) sensors are mandatory for many industrial applications. However, the development of H2S still remains a challenge researchers. In this work, we report study TiO2-based conductometric sensor monitoring at low concentrations. TiO2 samples were first synthesized using sol-gel route, annealed different temperatures (400 and 600 °C), thoroughly characterized to evaluate their morphological microstructural properties. Scanning electronic microscopy, Raman...
