A comparative study on the photocatalytic degradation of organic dyes using hybridized 1T/2H, 1T/3R and 2H MoS₂ nano-sheets

Abstract

MoS2 is a very attractive material and has been well studied for potential applications in various areas.

Sulfur promotes hydrogen evolution on molybdenum carbide catalysts

“…01-077-0720, b-Mo 2 C) 9,24 while higher sulfur loadings Mo 2 C (11 wt%) has additional MoS 2 crystalline phase patterns (PDF No. 00-024-0513), 25 which come from the MoS 2 formation by excess sulfur. For Mo 2 C, the obtained diffraction peaks are 34.31, 37.91, and 39.31 which are attributed to the (201), (020), and (211) planes of Mo 2 C. The crystallinity of Mo 2 C slightly decreased as sulfur doping (see the magnified XRD graphs in Fig.…”

Revealing the role of the 1T phase on the adsorption of organic dyes on MoS2 nanosheets

“…Two-dimensional (2D) layered materials have attracted attention for a wide range of applications including hydrogen evolution, 1 adsorption, 2,3 photocatalysis, 4,5 lithium ion batteries, 6 and supercapacitors. [7][8][9] Among the different types of 2D materials, molybdenum disulde (MoS 2 ) has been one of the most studied materials over the last few years.…”

“…[17][18][19] with 1T-phase concentration up to 70%. 5,18 Treatment of organic pollutants using MoS 2 materials via adsorption or photocatalytic degradation has been extensively studied. [1][2][3][4]6,7,12,20 However, several contradicting reports on this topic can be found due to the very delicate nature of the material.…”

Sonochemical Synthesis of Ga/ZnO Nanomaterials from a Liquid Metal for Photocatalytic Applications

“…In addition, other known physical and chemical treatments procedures are often cost prohibitive and can still be detrimental to the environment. [16,18] The photocatalytic application of metal oxide semiconductors (zinc oxide; ZnO, tungsten oxide; WO 3 , strontium titanate; SrTiO 3 , titanium dioxide; TiO 2 ) for synthetic dye degradation/ discoloration has been extensively demonstrated. ZnO and TiO 2 are among the most evaluated photocatalysts owing to their excellent physiochemical properties.…”
