Kolekar 4 & Sang-Wan Ryu1 BiVO4 is ubiquitously known for its potential use as photoanode for PEC-WS due to its well-suited band structure; nevertheless, it suffers from the major drawback of a slow electron hole separation and transportation. We have demonstrated the one-pot ...
The introduced heterostructure is thoroughly studied by SEM, TEM, Raman, UV鈥揤isible, and AFM analyses. The rGO/MoS 2 /Au NPs heterostructure demonstrates about 240% improvement in photocurrent density compared with GO/MoS 2 hybrid which is due to the efficient transfer of electrons to Au ...
UV–Visible spectroscopy and Raman analysis were also carried out to investigate optical properties of WO3-BiVO4. The band gap energy of WO3-BiVO4calculated from UV–Visible absorption and diffused reflectance spectroscopy's was observed to be 2.1eV respectively. The photoelectrochemical (PEC) studies...
Among various application fields, MoS2/WS2/WSe2 is applied to the thin‐film catalyst of a p㏒i photocathode, to effectively transfer the photogenerated electrons from p㏒i to the electrolyte in the photo〆lectrochemical (PEC) hydrogen evolution. From a comparison between the PEC performances of...
The fabricated MoS2/WS2/WSe2 thin film on p‐type silicon (p‐Si) substrate is designed to form multistaggered gaps (type‐II band structure) with p‐Si, and this film exhibits excellent spatial and thickness uniformity, which is verified by Raman spectroscopy. Among various application fields...
Raman spectra were studied on an NTEGRA Spectrometer (NT-MDT, Zelenograd, Russia) with solid-state laser excitation at a wavelength of 473 nm. 2.4. Electrode Preparation To manufacture electrodes from ZnO/Co3O4 and h-Zn-Co-O on nickel foam, a preliminarily annealed powder or as-synthesized...
Raman spectroscopy is a quick and easy method for finding more information about carbon. Carbon, ZnFe2O4 nanoparticles and ZnFe2O4@C nanohybrids are shown in Figure 3. Carbon and ZnFe2O4@C nanohybrids have G and D bands. The G band at Gels 2022, 8, 305 5 of 13 about 1580 cm−1...
[9], conducted an experiment using Raman microscopy to measure fluid film thickness between rotated and pressed polydimethylsiloxane sphere on a quartz flat disc. The results showed that the contact condition varied due to sliding speed. Fowel et al. [10] used fluorescence microscopy on soft ...
