Selected-control hydrothermal synthesis and photoresponse properties of Bi2S3 micro/nanocrystals

Bismuth Sulfide (Bi2S3) Nanorods as Efficient Photodetection Materials

“…For instance, a variety of preparation methods were explored to obtain Bi 2 S 3 nanorods, such as solvothermal or hydrothermal routes [4,9], microwave irradiation [10], colloidal synthesis [2,3,11], and thermalysis of single-source precursors [12]. Meanwhile, it is found that Bi 2 S 3 nanomaterials, such as nanorods, nanobelts and nanoflowers, display superior photo-responsibility to visible and near-infrared light and thus have been used in many photoelectric devices, such as photodetectors and optical switches [3][4][5][13][14][15][16].…”

Facile Synthesis, Characterization, and Visible-light Photocatalytic Activities of 3D Hierarchical Bi2S3 Architectures Assembled by Nanoplatelets

“…Bi 2 S 3 micro/nanostructures with various morphologies, including one-dimensional (1D) nanorods/nanowires, two-dimensional (2D) nanosheets/flakes, and three-dimensional (3D) hierarchical complex architectures, have been successfully fabricated in previous studies [10][11][12][13][14][15][17][18][19][23][24][25][26], since the properties of functional nanostructured materials are strongly dependent on the tailored morphology, microstructure and surface properties. Among them, 3D hierarchical complex architectures have exhibited excellent properties for applications in gas sensors, lithium batteries, and photocatalysts due to their large surface area and facile electron (ion) transport.…”

“…Therefore, the development of novel visible-light-driven photocatalysts is required for the purpose of taking full use of solar energy and improving quantum efficiency. In order 2 of 12 to achieve the goal, much research has been devoted to the modification of traditional TiO 2 [3][4][5][6][7] and the pursuit of other materials such as bismuth sulfide (Bi 2 S 3 ) [8][9][10].…”

“…With a direct narrow band gap of around 1.3 eV, bismuth sulfide (Bi 2 S 3 ), emerging as one promising member of group V-VI binary semi-conductors, has been attracting considerable attention due to its wide range of application in the field of solar cells [8,9], photo-detectors [10][11][12][13][14], gas sensors [14], thermoelectric devices [15], X-ray computed tomography imaging [16], lithium-ion batteries [17][18][19][20], and photocatalysis [21][22][23]. Bi 2 S 3 micro/nanostructures with various morphologies, including one-dimensional (1D) nanorods/nanowires, two-dimensional (2D) nanosheets/flakes, and three-dimensional (3D) hierarchical complex architectures, have been successfully fabricated in previous studies [10][11][12][13][14][15][17][18][19][23][24][25][26], since the properties of functional nanostructured materials are strongly dependent on the tailored morphology, microstructure and surface properties.…”

3D Hierarchical Bi2S3 Nanostructures by Polyvinylpyrrolidone (PVP) and Chloride Ion-Assisted Synthesis and Their Photodetecting Properties

“…Among them, 3D hierarchically porous and hollow nanostructures have showed enhanced properties for applications in lithium-ion batteries [21], photocatalysts [22], and gas sensors [23], because of their large surface area and facile electron (ion) transport. 3D hierarchical Bi 2 S 3 nanoarchitectures are usually produced through solution-based synthesis [4,13,24,25], and chemical vapor deposition routes [26] and their excellent physical and chemical properties have been revealed. In 2009, Li et al built their photodetectors with Bi 2 S 3 core-shell mircospheres.…”
