- Wastewater remediation is a hot research area aimed at reducing global water scarcity by treating pollutants in wastewater from various sources, which can improve both domestic water use and the aquatic environment.
- Researchers focused on creating efficient and cost-effective catalysts, specifically NiMoO nanorods, using a co-precipitation method with varying stirring times, with analysis techniques including XRD, FT-IR, Raman, and UV-vis spectroscopy confirming the product's properties.
- The study found that the NiMoO catalyst, particularly when prepared with a 6-hour stirring time, exhibited superior photocatalytic activity in degrading methylene blue dye, showing significantly higher efficiency under visible light compared to UV light.
Comparative investigation of the electrochemical oxygen evolution reaction (OER) activity for clean energy production was performed by fabricating three different electrodes, namely, NiSe, CoSe, and CoNiSe, synthesized by hydrothermal treatment. Cubic, orthorhombic, and hexagonal structures of NiSe, CoSe, and CoNiSe were confirmed by X-ray diffraction (XRD) and also by other characterization studies. Perfect nanospheres, combination of distorted nanospheres and tiny nanoparticles, and sharp-edge nanostructures of NiSe, CoSe, and CoNiSe were explored by surface morphological images.

Formation of single-phase β-NiS, Ni(OH) and composite-phase β-NiS@Ni(OH) has been thoroughly analyzed by X-ray diffractometer (XRD) spectra. Three different kinds of morphologies such as rock-like agglomerated nanoparticles, uniformly stacked nanogills, and uniform nanoplates for β-NiS, Ni(OH), and β-NiS@Ni(OH) materials, respectively, were confirmed by SEM images.

BiWO and FeWO nanocatalysts have been confirmed through the strong signature of (113) and (111) crystal planes, respectively. The binding natures of Bi-W-O and Fe-W-O have been thoroughly discussed by employing X-ray photoelectron spectroscopy which confirmed the formation of BiWO and FeWO.
