“…The synthesis of Ag 2 SnO 3 was divided into three steps: Na 2 -Sn(OH) 6 was rst prepared by the hydrothermal method; then the sodium ion was replaced by a silver ion in aqueous solution assisted by ultrasonic treatment; and nally the resultant was dried at 60 C to decompose Ag 2 Sn(OH) 6 and produce Ag 2 SnO 3 . 24,25 The detailed process is described in the ESI. †…”

nanoparticles were synthesized by irradiating Ag 2 SnO 3 with different doses of gamma rays ranging from 0 to 500 kGy. The irradiated products were employed to detect two reducing gases (ethanol and nitromethane) and one oxidizing gas (acetic acid). The response was found to be dependent on irradiation dose, which influenced the content of Ag. The results showed that the best gas-sensing performance was achieved at the dose of 400 kGy: the responses were enhanced 9, 6.3 and 10.6 fold compared with the unirradiated Ag 2 SnO 3 for ethanol, nitromethane and acetic acid, respectively.

“…Lastly, there was high photocatalytic ability for the degradation of methylene blue dye, and the increase in surface oxygen vacancies and hydroxyl groups contributed to this result. Other materials, such as Pt [168], Ag [169], Ga [170], and GdS [171] have also been found to be able to tune the photocatalytic properties of tin oxides.…”

For a very long period, tin was considered one of the most important metals for humans due to its easy access in nature and abundance of sources. In the past, tin was mainly used to make various utensils and weapons. Today, nanostructured tin and especially its oxide materials have been found to possess many characteristic physical and chemical properties that allow their use as functional materials in various fields such as energy storage, photocatalytic process, gas sensors, and solar cells. This review discusses current methods for the synthesis of Sn/SnO2 composite materials in form of powder or thin film, as well as the application of the most advanced characterization tools based on large-scale synchrotron radiation facilities to study their chemical composition and electronic features. In addition, the applications of Sn/SnO2 composites in various fields are presented in detail.

“…Among these metal oxides, SnO 2 is a highly intriguing metal oxide semiconductor of a negative nature with an optical bandgap of 3.6 eV at room temperature. The outstanding optical, electrical, and environmentally friendly qualities of this material make it suitable for a wide range of applications [25][26][27][28]. As a low-cost metal oxide that can be manufactured using simple techniques, researchers are interested in using SnO 2 to degrade industrial effluents through photocatalysis.…”

Photocatalysis triggered by visible light has emerged as a viable method for addressing environmental pollution and the energy crisis in our society. Numerous metal oxide semiconductors are transformed into visible light active photocatalysts by adopting some straightforward methods. One such efficient way of creating a visible light active photocatalyst is doping a pure semiconductor with plasmonic metal nanoparticles. Our work thoroughly investigates the photocatalytic properties of pure SnO2 nanoparticles (NP) and SnO2 doped with 1%, 3%, and 5% ‘Ag’ under sunlight. These samples are prepared using a straightforward sol–gel approach, followed by a hydrothermal procedure. To examine the different properties and morphology of the synthesized samples, several analytical tools, including UV–visible spectrometer, XRD, XPS, TEM, PL spectrometer and FTIR are used. Analysis of UV-visible absorbance spectra shows a noticeable narrowing of the band gap with increased ‘Ag’ doping. XRD analysis confirms the tetragonal structure of all samples. Methyl orange (MO) dye is used as an imitation of an organic pollutant to examine the photocatalytic activity under sunlight. When compared to pure SnO2 NP, every ‘Ag’ doped SnO2 NP sample exhibits a considerable improvement in the photodegradation of methyl orange. Analysis of PL spectra of SnO2 NPs doped with ‘Ag’ suggests that the major causes of this enhancement in photocatalysis are surface defects and the surface plasmon resonance (SPR) effect caused by ‘Ag’ doping. The scavenging test claims that the holes are the primary and the superoxide radicals are the secondary reactive species which are responsible for MO degradation under sunlight.
