Evaluation of Nickel Cobalt Tungstate Nanocomposites and Their Potential Photocatalytic Studies Using Acid Green and Acid Red Dyes

ABSTRACT Nickel cobalt tungstate (Ni (1‐X) Co X WO 4 ) nanocomposites with varying amounts of cobalt (X = 0.0, 0.3, 0.5, 0.7, and 1.0) are the focus of this investigation into photocatalytic effectiveness. Finding ways to improve these nanocomposites for use in photocatalysis is the primary goal of the study. Several methods were used to analyze the nanocomposites, such as field emission scanning electron microscope (FESEM), high resolution transmission electron microscopy (HRTEM), x‐ray diffraction (XRD), Fourier transform infrared (FTIR), UV‐Vis, x‐ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Using nanocomposites of nickel cobalt tungstate (Ni (1‐X) Co X WO 4 ), the adsorption and photodegradation of acid red (AR) and acid green (AG) from a solution including water were accomplished with success. When exposed to visible light, the nickel cobalt tungstate nanocomposite shows increased rates of adsorption and photodegradation compared to its behavior when no light is present. With an impressive rate of 89.54% AG removal and 87.16% AR removal in less than 60 min, the compound nickel cobalt tungstate showed great potential. When it comes to fighting AG and AR in visible light, photodegradation outperforms adsorption. This work presents a unique approach to evaluating the photocatalytic performance of nickel cobalt tungstate (Ni (1‐X) Co X WO 4 ) nanocomposites with varying amounts of cobalt. The results may shed light on how to improve these materials for use in energy and environmental protection. Contributing important information for the creation of more efficient and personalized photocatalytic materials, the research analyzes the influence of cobalt content on photocatalytic performance in a novel way.
