“…27 The photocatalyst activity of nanoparticles mainly depends on their high surface area, size, shape, and less band gap energy. 28 Tuan et al (2019) noticed that the photocatalyst activity of SnO 2 / rGO nanocomposites depends on their morphology, structure, and size. 29 Jiang et al (2021) studied the anode materials for the degradation of organic pollutants by anodic oxidation.…”

The sustainable synthesis of metal oxide materials provides an ecofriendly and more exciting approach in the domain of a clean environment. Besides, plant extracts to synthesize nanoparticles have been considered one of the more superior ecofriendly methods. This paper describes the biosynthetic preparation route of three different sizes of tetragonal structure SnO 2 nanoparticles (SNPs) from the agro-waste cotton boll peel aqueous extract at 200, 500, and 800 °C for 3 h and represents a low-cost and alternative preparation method. The samples were characterized by X-ray diffraction, Fourier transform infrared spectrophotometry, ultraviolet–visible absorption spectroscopy, high-resolution transmission electron microscopy (HR-TEM), and energy-dispersive X-ray spectroscopy. Surface area and porosity size distribution were identified by nitrogen adsorption–desorption isotherms and Brunauer–Emmett–Teller analysis. The photocatalytic properties of the SNP samples were studied against methylene blue (MB) and methyl orange (MO), and the degradation was evaluated with three different size nanomaterials of 3.97, 8.48, and 13.43 nm. Photocatalytic activities were carried out under a multilamp (125 W Hg lamps) photoreactor. The smallest size sample exhibited the highest MB degradation efficiency within 30 min than the most significant size sample, which lasted 80 min. Similarly, in the case of MO, the smallest sample showed a more superior degradation efficiency with a shorter period (40 min) than the large-size samples (100 min). Therefore, our studies suggested that the developed SNP nanomaterials could be potential, promising photocatalysts against the degradation of industrial effluents.

“…In essence, the bare SnO 2 nanostructures exhibit lacklustre photocatalytic and adsorption activities due to nanoparticle agglomeration, a sizable bandgap, and limited surface area [25,43,44]. The integration of rGO into the composite system precipitates a reduction in the bandgap of SnO 2 by introducing impurity states into its band structure.…”

“…For instance, Tuan et al delved into the intricate influence of hydrothermal reaction temperature, testing a range from 100 °C to 200 °C, on the breakdown of methylene blue (MB) dye. Their insightful investigation pinpointed the optimal temperature for efficient degradation to be 180 °C under solar irradiation [43]. Building on this, Shyamala and their team accomplished a remarkable feat by achieving dye degradation within a mere 50 min under solar irradiation, showcasing the swiftness of their nanocomposites in action [44].…”

This study presents the synthesis and characterization of rGO/SnO2 nanocomposites and investigates their efficacy in the adsorption and photocatalytic degradation of organic contaminants. The nanocomposites were synthesized via a one-step hydrothermal route, which is an environmentally friendly method without the use of hazardous reducing agents. The incorporation of rGO onto SnO2 nanostructures led to bandgap modification and increased specific surface area, synergistically enhancing the adsorption and photocatalytic properties of the nanocomposites. The influence of varying rGO concentrations on the performance of the nanocomposite was systematically examined. An optimal weight ratio of 15% of rGO was identified, providing the most effective adsorption-photodegradation synergy, resulting in the rapid degradation of organic contaminants under simulated sunlight irradiation. The nanocomposites demonstrated high degradation rates for a mixture of rhodamine B (RhB) and methylene blue (MB) dyes within 50 min. Scavenger experiments identified superoxide anion radicals (O 2 •−) and hydroxyl free radicals (OH•) as the primary active species involved in the photocatalytic degradation process. Furthermore, the study explored the influence of initial dye concentration and photocatalyst mass under optimized conditions. The interfacial contact between rGO nanosheets and SnO2 nanostructures played a crucial role in enhancing the photocatalytic performance by facilitating efficient charge carrier separation. The results indicated the efficient degradation of high concentrations of dyes and demonstrated the potential of rGO/SnO2 nanocomposites for real-world wastewater treatment applications. Overall, this study highlights the remarkable adsorption-photocatalytic synergy of rGO/SnO2 nanocomposites, offering a promising solution for the simultaneous degradation of mixed organic contaminants.
