Ultrathin hexagonal SnS2 nanosheets coupled with g-C3N4 nanosheets as 2D/2D heterojunction photocatalysts toward high photocatalytic activity

Heterostructured AgX/g-C3N4 (X = Cl and Br) nanocomposites via a sonication-assisted deposition-precipitation approach: Emerging role of halide ions in the synergistic photocatalytic reduction of carbon dioxide

“…5B), revealing that interactions were formed between the "nitrogen pots" of pCN and Ag species of AgBr. This phenomenon was in accordance with a recent report on SnS 2 /g-C 3 N 4 nanocomposites by Zhang et al [31].…”

“…This exemplified a walloping 34.1-and 4.2-fold enhancement in the CH 4 production over bare AgBr and pCN, respectively. Undoubtedly, there exists an optimal AgX content on the pCN surface to obtain the maximum photoactivity, which is basically similar to any dopants or co-catalysts such as metal, nonmetal or metal oxide [31,45,46]. In this work, when the loading of AgBr exceeded 30%, the total CH 4 evolution was deteriorated as shown in the 50AgBr/pCN (9.52 mol g catalyst −1 ) and 70AgBr/pCN samples (8.62 mol g catalyst −1 ).…”

Facile fabrication of Bi2S3/SnS2 heterojunction photocatalysts with efficient photocatalytic activity under visible light

“…Such dye molecules are difficult to be decomposed by natural means. Various methods, such as adsorption [6], advanced oxidation processes [7], biological treatment [8], electrocatalysis [9] and photocatalysis [10], have been developed to remove organic dyes. Among them, photocatalytic degradation of organic pollutants receives increasing interest owing to the absence of secondary pollution and the low cost by using solar light.…”

Heterojunctions in Composite Photocatalysts

“…17). SnS 2 RhB degradation, MO degradation, 4-NP degradation [118] In this example, PEDOT:PSS and Pt are acting as charge mediators for holes (to the TEA) or for electrons (from the conduction band), respectively, thus acting as co-catalysts. Other electron mediators include graphene-derived carbon, such as GO or rGO (as described in Sect.…”
