In this study, a new and facile process was developed for the preparation of composite catalysts based on tungsten oxide (WO3) by batch reactor routes. The structures, morphologies, compositions, and characteristics of synthesized materials were investigated and confirmed. Using batch reactor processes, WO3 nanorods (WO3 NR), heterostructures of WS2/WO3 nanobricks (WS2/WO3 NB), and WS2/WO3 nanorods (WS2/WO3 NR) were successfully prepared. The prepared materials were then employed for hydrogen evolution reaction (HER) to investigate their catalytic performance. The results indicated that the electrocatalytic activities of WS2/WO3 NR are significantly improved compared to those of WO3 NR and WS2/WO3 NB. This improvement could be attributed to the formation of heterostructure between WS2 and WO3 elements in highly uniform materials, which could create the synergistic effect and further improve the catalytic activities of the catalyst. The data shows that the Tafel slope of WS2/WO3 NR (82.7 mV dec−1) is significantly lower than that of WO3 NR (112.5 mV dec−1) and WS2/WO3 NB (195.5 mV dec−1). Furthermore, the resistance of WS2/WO3 NR (397.7 Ω) is markedly decreased compared to those of WO3 NR (1816 Ω) and WS2/WO3 NB (3597 Ω). The results indicate that WS2/WO3 NR could be a great catalyst for electrochemical applications.

In this work, green and low-cost Ni Nanoparticles/Tissue-derived Nitrogen-doped Porous Carbon Nanocomposites (NiNPs/T-dNPCNs) are prepared through a simple one-step pyrolysis process. The surface morphology and composition of the NiNPs/T-dNPCNs are characterized by X-Ray Diffraction (XRD), Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and X-ray Photoelectron Spectra (XPS). The NiNPs/T-dNPCNs modified glassy carbon electrode (NiNPs/T-dNPCNs/GCE) exhibits good electrocatalytic activity to Methanol Oxidation Reaction (MOR) in alkaline solution. Among them, the mass activity of the NiNPs/T-dNPCNs800 (carbonization at 800 ℃) is 3,349 mA·mgNi-1, which is much higher than that of the NiNPs/T-dNPCNs carbonized at other temperatures (600, 700, 900 ℃). In addition, the mass activity of the NiNPs/T-dNPCNs800 is 6.91 times higher than that of the commercial Pt/C. The NiNPs/T-dNPCNs800/GCE also displays high stability, fast reaction kinetics and well resistance to carbon monoxide poisoning. Therefore, as a new biomass-derived non-noble metal MOR catalyst, the NiNPs/T-dNPCNs800 will play an inspirational role in the development of MOR catalyst.

The world is currently grappling with a significant challenge, marked by environmental pollution, amidst the abundance of energy and opportunities. Nevertheless, to overcome such adverse effects, scientific methodologies must be adapted, and among those, electrochemical sensors have emerged as a promising tool for the primary detection of various pollutants in real samples. Herein, we have developed the distinctive type of electrochemical sensor with Cd doped TiO2 as sensor material for the detection of a nitroaromatic contaminant, chloramphenicol (CAP). Cd-TiO2 was synthesised by the sol-gel, followed by a hydrothermal process to obtain the Cd-doped TiO2 sensor material. Further, it underwent various characterization techniques like XRD, FT-IR, HR-TEM, and EIS. Moreover, to determine the detection facility, CV and LSV techniques were deployed. Proven results with a remarkable low limit of detection 3.5 nM and a linear concentration range were found to be 1 µm to 25 µm. Real sample analysis was conducted with different samples: Honey and coconut water. Additionally, DFT studies were conducted to verify the HOMO-LUMO of CAP and electrostatic potential. The results obtained were accurate and could be chosen as best sensor material for the detection of CAP in real-world analysis.
