Controlling morphologies of Bi2S3 nanostructures synthesized by glycolthermal method

Mini‐Review: Progress on the Controllable Synthesis of Micro/Nanoscale Bi2S3 Functional Materials

“…The ill-defined nanorods and nanoplates were obtained under the condition of no PVP and lower molar ratio of PVP to BiCl 3 . Furthermore, Phuruangrat et al [66] prepared Bi 2 S 3 nanostructures with different morphologies, such as nanorods, nanowires, straw-sheaves, and flower-like micrometer particles at 180 °C for 12 h, with l-cysteine as the sulfur source. EG, propylene glycol (PG), and PEG with different molecular weights (200, 300, 400, and 600) were used as solvents.…”

“…The reaction kinetics can be affected by the numbers of initial nucleations through altering the reaction parameters, so as to cause the oriented growth of crystal structure sorts and further influence the properties of materials, such as the size, shape, structure, and purity of these materials. [29] Up to now, typical structures of Bi 2 S 3 (such as nanowires, [30,31] nanorods, [32][33][34][35] nanotubes, [36][37][38] nanobelts, [39] nanowhiskers, [40] nanoflowers, [41][42][43] snowflakelike, [44] and urchin-like nanospheres [45] ) have been successfully gained via the hydrothermal, [46][47][48][49][50][51][52][53][54][55][56][57][58][59] solvothermal, [60][61][62][63][64][65][66][67][68][69][70][71][72] ionic liquid-assisted, [73][74]…”

“…It could has been used as a photoanode materials in DSSC due to its ability to absorb a large part of visible light up to 800 nm and transfer the electron from Bi 2 S 3 to TiO 2 conduction band. So far, there are many classic preparation methods for Bi 2 S 3 , such as hydrothermal method, solvothermal method, electrochemical deposition, microwave refluxing, organometallic complex decomposition and chemical vapor deposition 22 23 24 25 26 27 28 .…”
