“…The band gap energy of SnO2 NPs calcined at temperatures equal to or below 500 °C is evidently greater than that of bulk cassiterite materials or rock-like SnO2 NPs synthesized through a simple solution method [75]. This suggests that the photocatalytic activity of these samples may be more suitable for application under UV-light irradiation [61,77]. The band gap energy level in the present work is deemed more advantageous compared to SnO2 NPs synthesized using a higher concentration of SnCl2 hydrate, which exhibit band gap energy of no less than 3.93 eV [46,60].…”

In recent years, numerous studies have been conducted to combine tin oxide (SnO2) with various semiconductor materials to boost its photocatalytic efficiency for water waste treatment, with minimal emphasis placed on intensifying the intrinsic capabilities of pure SnO2. The primary objective of this study is to enhance the photocatalytic efficiency of pure SnO2 nanoparticles (NPs) by modifying their morphology, structural, and optical properties. The SnO2 NPs were synthesized using precipitation method, followed by a calcination process at varying temperatures (non-calcined, 300 °C, and 500 °C). The changes in properties of SnO2 NPs were investigated utilizing X-ray diffraction (XRD), scanning electron microscopy (SEM), particle size analysis (PSA), Brunauer-Emmett-Teller (BET), and ultraviolet-visible (UV-Vis) spectroscopy. The results indicated that elevating the calcination temperature up to 500 °C resulted in an increase in both the average crystallite size (up to 10.50 nm) and crystallinity (up to 85.28 %). However, the highest photocatalytic efficiency for methylene blue degradation of 84.78 % was obtained from the SnO2 NPs calcined at 300 °C sample exhibiting the largest surface area of 83.97 m2g-1. This study affirms that the specific surface area of SnO2 NPs is a critical factor in their efficacy for degrading dye-contaminated water waste.
