Solvothermal Synthesis of Ternary Cu₂MoS₄ Nanosheets: Structural Characterization at the Atomic Level

Abstract

Cu2 MoS4 nanosheets are synthesized by a solvothermal method in which the Cu2 O starting material acts as a sacrificial template. The microstructure of the Cu2 MoS4 nanosheets is characterized at the atomic level, and the growth mechanism is monitored at the nanoscale through systematic time-dependent experiments. As a result, the unprecedented observation of the allotropic phase change in Cu2 MoS4 that occurs during the solvothermal process is possible.

Cube-like Cu2MoS4 photocatalysts for visible light-driven degradation of methyl orange

“…peaks can be attributed to (010), (001), (011), (111), (021), (220), (022) and (221), which are agreeing with the above HRTEM observations. Furthermore, it is notable that the diffraction peaks for P-Cu 2 MoS 4 nanocubes are wider than that of our previous-reported nanosheets, 13 replying its comparable smaller size. To the best of our knowledge, this is the first time of controllable fabrication of cube-like Cu 2 MoS 4 nanocrystals with low-index facets and high crystallinity.…”

“…Recently, we have reported a sheet-like Cu 2 MoS 4 with I-phase structure synthesized by a hydrothermal method. 13 In this study, we further adjust the growth parameters and conditions to mass-produce, for the first time, a cube-like Cu 2 MoS 4 nanoparticle with low-index facets and high crystallinity for efficient photocatalytic degradation of methyl orange (MO).…”

“…13 For the selective fabrication of nanocube, 30 mg sodium molybdate (Na 2 MoO 4 ·2H 2 O) and 60 mg thioacetamide (C 2 H 5 NS) were firstly dissolved in 20mL ethylene glycol. Then, 18 mg of Cu 2 O powder was added and dispersed in the mixed solution by sonification for 5 min.…”

Fabrication of Lead Borate Single Crystal Nanosheets for Attenuating Both Neutron and Gamma Radiations

“…[10] Compared with other shapes, 2D fillers are beneficial to achieve low percolation threshold for constructing firm network structures and exhibiting superior performance. [13] The structure was characterized with XRD, SEM, and TEM. [12] [*] Dr. Q.-P. Zhang In this paper, lead borate nanosheets were fabricated by a facile solvothermal method, that is, of an extensive use for the synthesis of inorganic nanostructures.…”

Raman scattering of single crystal Cu2MoS4 nanosheet

“…9 The I-Cu 2 MoS 4 nanosheet with I-42m structure was formed by layers of edge-sharing MoS 4 and CuS 4 tetrahedra separated by a weak Van Der Waals gap. In this work, we further report a study of Raman scattering performed on a single crystal Cu 2 MoS 4 nanosheet.…”
