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.

“…Graphitic carbon nitride (g-C 3 N 4 ) has been a promising metal-free semiconductor photocatalyst and a well-established visible-light-triggered photocatalytic material based on its band gap of about 2.76 eV. − It has been applied to many different fields, such as photodegrading organic contaminants, − producing H 2 and O 2 over water splitting, − conversion of CO 2 by photocatalysis, − and so on. Hussain et al synthesized a series of sulfur (S)-, phosphorus (P)-, and boron (B)-doped g-C 3 N 4 through thermal decomposition of urea.…”

In this paper, g-C3N4-based hydrogel with a 3D network structure was synthesized via a simple and cheap reaction, using hydroxyethyl cellulose (HEC) and graphitic carbon nitride (g-C3N4) as the main materials. Electron microscope images revealed that the microstructure of g-C3N4-HEC hydrogel was rough and porous. The luxuriant scaly textures of this hydrogel were due to the uniform distribution of g-C3N4 nanoparticles. It was found that this hydrogel showed great removal ability of bisphenol A (BPA) through a synergistic effect of adsorption and photodegradation. The adsorption capacity and degradation efficiency of g-C3N4-HEC hydrogel (3%) for BPA were 8.66 mg/g and 78% under the conditions of C 0 = 9.94 mg/L and pH = 7.0, which were much higher than those for the original g-C3N4 and HEC hydrogel. In addition, g-C3N4-HEC hydrogel (3%) exhibited excellent removal efficiency (98%) of BPA (C 0 = 9.94 mg/L) in a dynamic adsorption and photodegradation system. Meanwhile, the mechanism of removal was investigated in depth. The superior batch and continuous removal capability of this g-C3N4-based hydrogel make it promising for environmental applications.
