In this paper, a basic solvothermal synthesis using sodium tungstate as a precursor is reported to prepare tungsten oxide (WO 3 ) particles. XRD data confirmed the highly crystalline nature. The broad peaks of XRD patterns estimated the nanocrystallites of WO 3 . The average crystallite size as was 95 nm. Scanning electron microscopy showed the morphologically cube-like particles with aggregation that was converted to larger brick-like particle of WO 3 after calcination. WO 3 was used as fuel additive in diesel oil. Fire and flash points of diesel oil were enhanced to 49°C and 54°C respectively. The calorific value was increased up to 36580 Jg −1 . Thus fuel efficiency was enhanced by use of WO 3 as an additive. The use of different concentrations of WO 3 (20, 40, 60, 80 ppm) as fuel additive has been also explored in this paper. The observed additive properties of WO 3 suggested the potential applications of such metal oxides.

“…Therefore, its main drawback is that it provides low photocatalytic degradation when employed for the photodegradation of dye into minerals. Several semiconductors other than TiO 2 based compounds, such as ZnO, [18] gC 3 N 4 , [19] BiPO 4 , [20] and WSe 2 [21] have been studied for photocatalytic degradation of dyes. Different strategies such as the addition of noble metals or oxides on semiconductors, [22][23][24][25][26][27] semiconductors with various crystalline structures, [28][29] heterogeneous photocatalysis where semiconductor-semiconductor nanocomposites [30][31] are employed to enhance photocatalytic activity to the degradation of dye.…”

Semiconductor‐assisted photocatalytic treatment is among the most effective methods for eliminating persistent contaminants from industrial wastewater. This study presents a hydrothermal approach for the preparation of Cobalt Telluride (CoTe) nanosheets for the degradation of aniline blue dye under visible light irradiation. The synthesized catalyst was characterized using various techniques, including X‐ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X‐ray spectroscopy (EDX), Fourier transform infrared (FTIR) spectroscopy, RAMAN spectroscopy, high‐Resolution transmission electron microscopy (HRTEM), and X‐ray photoelectron spectroscopy (XPS). Tauc's model was used to determine the optical band gap. The key operating parameters, such as the amount of CoTe, initial aniline blue (AB) concentration, and contact time, have been optimized to achieve the highest AB degradation percentage. Under visible light, 98 % of dye degradation occurred within 60 minutes. The degradation process was further assessed using total organic carbon (TOC) measurements. Free‐radical capture experiments were conducted to identify the role of radical species in the photocatalytic process. The photocatalytic process revealed that the equilibrium data aligns well with the Langmuir‐Hinshelwood kinetic model. A rate constant of 0.03486 min−1 was obtained. The photocatalyst demonstrated excellent recyclability, maintaining efficiency and structural integrity over five cycles. The photocatalytic experiment results also have been confirmed by a density functional theory (DFT) calculation.
