Fabrication of fibrous BiVO4/Bi2S3/MoS2 heterojunction and synergetic enhancement of photocatalytic activity towards pollutant degradation

In situ construction of superhydrophilic crystalline Ni3S2@amorphous VOx heterostructure nanorod arrays for the hydrogen evolution reaction with industry-compatible current density

“…In addition, the difference between the two peaks is about 7.4 eV, indicating that V may exist in the form of V 2 O 5 . 37,40 And no V signal was detected in the TF–NS/NF sample.…”

“…CV was carried out in 1 M KOH to probe the electrochemical double-layer capacitance of the various samples at non-faradaic overpotentials to estimate the effective electrode surface areas. Accordingly, a series of CV measurements were performed at various scan rates (20,40,60,80, 100 and 120 mV s −1 ) in −0.95 to −1.05 V vs. RHE, and the sweep segments of the measurements were set to 10 to ensure consistency. By plotting the difference in current density ( J) between the anodic and cathodic sweeps ( J anodic -J cathodic ) at −1.00 V vs. RHE against the scan rate, a linear trend was observed.…”

Selective Electrochemical Sensing Platform Based on the Synergy between Carbon Black and Single-Crystalline Bismuth Sulfide for Rapid Analysis of Antipyretic Drugs

“…One-dimensional (1D) materials such as nanoribbons, nanotubes, nanowires, and nanorods based on Bi 2 S 3 and their catalytic ability have attracted more attention in recent decades for electrochemical sensor applications . They can be synthesized using various experimental methods, including hydrothermal, reflux condensation, sonochemical, microwave irradiation, and vapor deposition . Rodlike Bi 2 S 3 nanomaterials are of significant interest in electrochemical sensor applications .…”

Experimental and Theoretical Investigation of Degradation Activity of Layered Two-Dimensional MoS2-ZnS Nanocomposites

“…Transition metal dichalcogenides (TMDs) show unique properties such as tunable band gap, strong oxidization power, non-toxicity etc. 2 Among different TMDs, molybdenum disulfide (MoS 2 ) is a more suitable and convenient material due to its preferred physical and chemical properties and band gap which contribute to higher efficiency of photocatalysis under visible light. It is a narrow-band gap material that shows visible light absorption and electron-hole pair generation under photo excitation.…”

“…Previous studies indicate that the photocatalytic efficiency of MoS 2 materials have not been exploited well enough at an industrial scale because of fast recombination of photo-induced electrons and holes due to their narrow band gap. 2,3 Huang et al 4 have studied the photocatalytic dye degradation efficiency of MoS 2 for thiobencarb, where they observed almost 95% degradation efficiency.…”
