Potential progress in SnO2 nanostructures for enhancing photocatalytic degradation of organic pollutants

An overview of prominent factors influencing the photocatalytic degradation of cationic crystal violet dye employing diverse nanostructured materials

“…The primary internal factor affecting the rate at which CV degrades is the nature of the nanomaterials used. According to the nature of the nanomaterials, assemblies made of more difficult or advanced structural and morphological features have been shown to lead to more rapid degradation than those made of basic or easy nanomaterials 137,138 . Meshram et al 104 .…”

“…Calculating nanomaterial reusability potential is one of the essential processes in analyzing the application potential of newly developed nanomaterial photocatalysts 138 . The potential for reusing the photocatalyst has become difficult to document nowadays.…”

Visible light photocatalytic NOx removal with suppressed poisonous NO2 byproduct generation over simply synthesized triangular silver nanoparticles coupled with tin dioxide

“…12–22 As an n-type metal oxide semiconductor, SnO 2 has been extensively applied in photo-electrochemistry because of its advantages, such as high stability, non-toxicity, and cost-effectiveness. However, the use of SnO 2 as a single catalyst is not efficient enough due to the large bandgap and rapid charge recombination; 23 accordingly, many modification strategies such as doping, 24,25 morphology control, 26,27 and incorporation of a co-catalyst 28,29 have been devoted to further enhance the photocatalytic efficiency. Among these approaches, coupling with a plasmonic co-catalyst, typically silver (Ag), is beneficial for not only expanding the light absorption range but also enhancing photogenerated charge separation.…”

Green synthesis and photocatalytic proficiency of tunable SnO2 nanostructures: unveiling environmental-friendly strategies for sustainable water remediation

“…Hence, the elimination of these water pollutants for the reclamation and reuse of wastewater is an imperative requirement of the global community for the sustainable advancement of the expanding global economy. Various techniques, such as coagulation, flocculation, adsorption, membrane separation, and enhanced oxidation processes, have been employed worldwide to tackle the problem of wastewater [3][4][5][6]. Adsorption is one of the commercially viable and cost-effective methods for removing organic and inorganic pollutants from effluents [7][8][9].…”

“…The metal oxide semiconductors (TiO 2 , SnO 2 , ZnO, and V 2 O 5 ) have garnered global interest for their potential applications in gas sensing, photocatalysis, antimicrobial activities, energy storage devices, and transparent conducting electrodes [6,13]. Metal oxides are highly effective photocatalysts for breaking down organic pollutants due to their exceptional physical, chemical, and thermal stability, cost-effectiveness, appropriate band-edge position, and environmentally benign properties.…”
