“…In the 2H phase of WS 2 , the catalytically actives usually occur at the layer’s edge, whereas in the 1T phase, the active sites are found at both the edge and the basal plane. On the other hand, 2H phase is significant if the surface area is concerned . Therefore, the combined action of the 1T and 2H phases in P-doped WS 2 could lead to exceptionally high photocatalytic activity by improving the charge separation efficiency.…”

The utilization of earth-abundant natural resources, such as solar energy, for photocatalytic hydrogen production offers a potential way to mitigate the impacts of fossil fuels. Here, we suggest the heterostructure formation of CdS nanorods with phosphorus-doped (P-doped) dual-phase WS 2 nanosheets (1T-2H), with the goal of exploring an extremely efficient photocatalyst for solar water splitting. 1T-2H-transformed WS 2 -P nanostructures exhibit a semimetallic nature with high electronic conductivity and are enriched with both basal and edge-active sites to promote charge carrier kinetics. This may drive the achievement of a high rate of hydrogen evolution by CdS/WS 2 -P nanostructures (262.12 mmol•g −1 •h −1 ) emphasizing the synergistic interaction of CdS with dual-phase (1T-2H) WS 2 -P nanostructures. Furthermore, the stability analysis demonstrates that CdS/WS 2 -P nanostructures are extremely stable for more than 60 h under continuous solar irradiation, highlighting their large-scale applications. Overall, this work offers an example of how to overcome the efficiency barrier of a photocatalyst for solar hydrogen production via heterojunction creation of CdS with dual-phase WS 2 nanosheets.

Electrochemical Detection of Flutamide by the Composite of Complex Based on Thiacalix[4]arene Derivatives and Reduced Graphene Oxide

et al. 2023

View full text Add to dashboard Cite

In this paper, a thiacalix [4]arene complex [Zn 2 (TIT4A)L 2 ]•4DMF•2CH 3 OH (H 2 L = 4,4′-oxybisbenzoic acid) (Zn-TIT4A-L) was synthesized by a solvothermal method. The composites were prepared by combining Zn-TIT4A-L with reduced graphene oxide (RGO), mesoporous carbon (MC), and multi-walled carbon nanotubes (MWCNTs), respectively. Three representative composites are Zn-TIT4A-L@RGO(1:1), Zn-TIT4A-L@MC(1:2), and Zn-TIT4A-L@MWCNT(1:2). X-ray diffraction and scanning electron microscopy characterized their structures and morphologies. The results showed that three composites were successfully prepared, and the crystals of the complex remained in the composites. The electrochemical properties of the composites were characterized by electrochemical impedance spectroscopy and cyclic voltammetry. The results indicated that they had good electrocatalytic activity and conductivity. Among them, Zn-TIT4A-L@RGO(1:1) had the best performance and was used for the quantitative detection of flutamide (FTA). The linear range of detection is 0.1−200 μM, and the limit of detection is 0.015 μM. At the same time, the sensor also had good reproducibility, anti-interference, and stability. The sensor was also used for the detection of FTA in lake water, human urine, and serum with a satisfactory recovery rate. The possible mechanism of electrochemical detection of FTA was also discussed.
