Synthesis and spectroscopic analysis of undoped and Zn doped SnS2 nanostructure by solid state reaction method

Facile microwave-assisted synthesis of SnS2 nanoparticles for visible-light responsive photocatalyst

“…26 nm and 15-20 nm, respectively (Table 1). When SnS 2 was prepared by hydrothermal method, crystallite size was usually 10-30 nm [11,16]. While, the particle size of SnS 2 -A and SnS 2 -M calculated with (1 0 0) peak ( Fig.…”

“…As mentioned before, this method requires high temperature, high pressure, or tedious processing times. To overcome these drawbacks, a solid state reaction without solvents was recently proposed to synthesize ZnSnS 2 , but high temperature was required to treat the reactant [16]. In addition, precipitation methods were suggested to synthesize SnS 2 at room temperature, but the crystallinity of asmade SnS 2 was poor [17].…”

Preparation of worm-like SnS2 nanoparticles and their photocatalytic activity

“…And they found that approximate 99% Cr (VI) can be reduced over the above-mentioned SnS 2 nanosheets within 100 min under irradiation [20]. Besides, various SnS 2 -based photocatalysts which possess high photocatalytic activity for the remove of Cr (VI) have been also reported, including CNT@MoS 2 /SnS 2 nanotubes [21], flower-like In 3þ -doped SnS 2 [22], core-shell structured WO 3 @SnS 2 heterojunction [23], SnS 2 nanotubes [24], Zn doped SnS 2 nanostructure [25], SnS 2 quantum dots/reduced graphene oxide composites [26], and SnS 2 modified with N-doped carbon quantum dots [27]. These reported results indicate that the SnS 2 -based photocatalysts should be a promising candidate which might be applied at large scale in the elimination of Cr (VI).…”

“…However, before their large-scale practical application, the activity of the SnS 2 -based photocatalysts need be still further enhanced although they exhibited fairly high photocatalytic activity. Now, the common methods for improving the photocatalytic activity of the SnS 2 -based photocatalysts are mainly divided into some categories as follows, (1) tuning its morphology [28], (2) fabricating heterojunction [23], (3) doping with metal [25], (4) loading co-catalyst [29], and so on. Therein, tuning the morphology of nanostructured SnS 2 is known to be one of the most simple and efficient routes to fabricate a SnS 2 -based photocatalytic system with dramatic photocatalytic performance.…”

N-Tipi SnS2 Yarıiletken İnce Filmlerin Hazırlanması ve Karakterizasyonu

“…Yarıiletkenler, elektrik-elektronik mühendisliğinde yaygınca kullanılan malzemelerdir. Yarıiletken malzeme olan SnS2 ince filmleri, iyi optiksel özelliklere sahip olmaları, 0.8-2.88 eV kadar değişen enerji bant aralık değerleri alması ve n veya p-tipi elektriksel özellik göstermelerinden dolayı güneş pillerinde soğurucu ve pencere tabakası olarak kullanılmaktadır [1][2][3]. S-Sn-S sandvich katmanları kristal yapıda, kimyasal anlamda doygun, iki boyutlu kovelent bağlı olarak oluşur.…”
