“…[ 70,80–82 ] The positive slope confirmed the n‐type conductivity of WO 3, and the electron concentrations for the WO 3 :150 °C:10 min and WO 3 :180 °C:10 min films were N D = 1.72 × 10 19 and 1.10 × 10 19 cm −3 , respectively. The values have been estimated from the MS relation, as follows [ 83–86 ]

C_{SC}^{- 2} = 2 / [e ε ε_{0} A^{2} N_{normalD} (E - E_{fb})]

where e is the electron charge, ε the dielectric constant of WO 3 ( ε = 8), [ 87 ] ε 0 the permittivity of vacuum (8.85 × 10 −14 F cm −1 ), A the surface area, and N D the electron density, and 1 kHz was the frequency used for the measurements. The N D values are within the reported values for pure WO 3 .…”

Tungsten oxide (WO3) nanostructured films are synthesized under microwave radiation with synthesis times of 5 and 10 min, at 150 or 180 °C. This ultrafast synthesis route results in uniform and well‐crystallized WO3 nanostructured films fully covering the substrates. A plate‐like hierarchical structure is observed at 150 °C, and closely packed rectangular nanorods are formed at 180 °C. For both temperatures, the nanostructures self‐organize into larger flower‐like structures. The increase of the synthesis time from 5 to 10 min at 180 °C results in thicker films, reaching ≈4 μm. X‐ray diffraction (XRD) and Raman spectroscopy reveal that the films grow with the WO3 orthorhombic crystalline phase (o‐WO3·0.33H2O). Photoluminescence (PL) measurements are performed for all the films, and their optical bandgaps are estimated through diffuse reflectance spectroscopy. The WO3 films have their photocatalytic activity assessed from rhodamine B (RhB) degradation under solar radiation. The Mott–Schottky plots confirm the n‐type character of the films with the flat‐band potentials and electron concentrations being estimated for the best photocatalysts. This study associates the eco‐friendly, fast, and low‐cost aspects of the synthesis route to the production of highly photoactive materials, which can effectively contribute to environmental remediation.

“…These properties are conferred because of their characteristics size, shape and surface area [14][15][16][17][18][19][20]. Nanostructure semiconductor oxide such as TiO 2 , ZnO, SnO 2 and so on is reported to be a proficient photocatalyst for the degradation of organic pollutants [21][22][23][24][25][26][27][28]. The greater part of the semiconducting oxides used for water purification are n-type among this nanostructure TiO 2 is the most intensively studied [29,30].…”

This work sought to draw a comparison between the photocatalytic proficiency of NiO nanoparticles (NPs) for the degradation of Methylene blue (MB) and Rhodamine B (Rh B) dye. The NiO NPS were synthesized by a facile straightforward chemical route by utilizing NiCl 2 and NaHCO 3 as a precursor. The morphological characteristics of the synthesized NiO NPs have been characterized by using SEM. In addition XRD, FTIR and EDX analysis were also carried out to investigate the crystalline size, functional group and elemental composition of the NPs. The NiO NPs were subsequently used for the photocatalytic degradation of the MB and Rh B in the presence of the visible light irradiation. For evaluation of photocatalytic proficiency, the influence of various key parameters viz. pH of the dye solution, initial dye concentration, Irradiation time and amount of the catalyst were investigated. The extent of photocatalytic degradation of MB and Rh B was found to be 98.7 and 80.33% at pH 2 and 10 respectively. The kinetic investigation of photocatalytic degradation followed a pseudo-first-order rate kinetics for MB and Rh B dye with rate constant 4.6 × 10 −1 and 3.6 × 10 −2 . Additionally, the synthesized NiO NPs was used for the antimicrobial activity against the few gram-positive and gram-negative microorganisms. Highlights• The NiO nanocrystalline semiconducting photocatalyst was successfully synthesized by a facile straightforward chemical route by utilizing NiCl 2 and NaHCO 3 as a precursor. • Novel simple chemical route synthesis at room temperature.• First time report a combine study of photocatalytic degradation of Methylene blue and Rhodamine B dye by using NiO as a photocatalyst. • Also, Antimicrobial study was examined which clearly indicate the biocompatibility of synthesized NiO nanoparticles.
