“…This metal sulfide has attracted scientific interest for a broad range of applications, including electronic and optoelectronic devices [19], photocatalysis [20][21][22] and hydrogen storage [23,24]. Recently, the unique pseudocapacitive behavior of Bi 2 S 3 , which was reported by Nie et al [25], has attracted more attention, and the metal sulfide has been studied as a supercapacitor electrode material [20][21][22][24][25][26][27][28][29][30][31][32] due to its remarkable specific capacitance reaching up to 400 F g -1 [33]. The key to further progress in electrode material design is to establish the effect of different properties, such as the nanoparticle size and morphology of synthesized metal sulfides, on the electrochemical performance.…”

“…According to previous reports [39,40], syntheses in mixed solvents favor the formation of nanostructures with more uniform sizes and uncommon architectures compared with syntheses in single solvents. Most reports have focused on the synthesis of Bi 2 S 3 in water [19,22,23,25,27,34,38,41]. The usage of other solvents, including ethanol [21], ethylene glycol [20] or glycerol [36], has been rarely reported.…”

“…All of these structures have been obtained using various approaches, including solvothermal syntheses [21,22,27,28,30,34,38]. The nanostructure of Bi 2 S 3 is highly sensitive to synthesis parameters such as the substrate molar ratio [27,34], temperature [22,34,39], synthesis time [34] and sulfur precursor [38,39]. However, optimizing the solvothermal process by altering the solvent mixture has not attracted much attention.…”

“…Therefore, attempts have been made to develop an easily replicated and morphology-controlled synthesis method for Bi 2 S 3 . Thus far, the most commonly reported Bi 2 S 3 structures are nanorods [20,23,25,28,[34][35][36] and more complex architectures, such as nanoflowers [24,27,29,32] or nanospheres [37], composed of nanorod-like units. All of these structures have been obtained using various approaches, including solvothermal syntheses [21,22,27,28,30,34,38].…”

In our study, we report a facile solvothermal method for the synthesis of Bi 2 S 3 nanoparticles with unique morphologies using water and mixed solvent systems, such as ethylene glycol/water (1:1, v/v) and butyldiglycol/water (1:1, v/v). Altering the solution mixtures used in the solvothermal synthesis allowed the shape of the Bi 2 S 3 nanoparticles to be controlled. The synthesis of Bi 2 S 3 in water at 150°C for 24 h led to the formation of sphere-like particles 100-300 nm in size. Very uniform spherical nanospheres with diameters from 50 to 90 nm formed when ethylene glycol/water mixture (1:1, v/v) was used as the solvent under the same solvothermal conditions. The butyldiglycol/water mixture promoted the formation of plate-shaped Bi 2 S 3 nanoparticles composed of nanorods. The electrochemical properties of the Bi 2 S 3 samples were determined in a three-electrode cell in 6 mol L -1 KOH using cyclic voltammetry, galvanostatic charging/discharging and impedance spectroscopy. Among the synthesized materials, the Bi 2 S 3 sample obtained in the butyldiglycol/water mixture exhibited a superior capacitive behavior with an outstanding capacitance of 550 F g -1 (at 0.5 A g -1 ), and great cycle stability, which was reflected by a capacitance retention of 87% after 500 charge/discharge cycles. These results demonstrate the high potential of Bi 2 S 3 as an active electrode material for supercapacitors.

Bismuth(Bi)‐based materials have gained considerable attention in recent decades for use in a diverse range of sustainable energy and environmental applications due to their low toxicity and eco‐friendliness. Bi materials are widely employed in electrochemical energy storage and conversion devices, exhibiting excellent catalytic and non‐catalytic performance, as well as CO2/N2 reduction and water treatment systems. A variety of Bi materials, including its oxides, chalcogenides, oxyhalides, bismuthates, and other composites, have been developed for understanding their physicochemical properties. In this review, a comprehensive overview of the properties of individual Bi material systems and their use in a range of applications is provided. This review highlights the implementation of novel strategies to modify Bi materials based on morphological and facet control, doping/defect inclusion, and composite/heterojunction formation. The factors affecting the development of different classes of Bi materials and how their control differs between individual Bi compounds are also described. In particular, the development process for these material systems, their mass production, and related challenges are considered. Thus, the key components in Bi compounds are compared in terms of their properties, design, and applications. Finally, the future potential and challenges associated with Bi complexes are presented as a pathway for new innovations.

The quest for developing the scalable methods of synthesis of materials with potential electrochemical energy storage applications remains a great challenge. Herein, we propose a facile, one-step chemical precipitation method for the synthesis of Bi 2 S 3 with the nanorods morphology. Influence of different synthesis temperatures on the physical, chemical, and electrochemical performance was investigated. Relatively low BET surface area and mesopore volume of Bi 2 S 3 increased with the higher reaction temperature. Bismuth sulfides synthesized at various temperatures were used as an electrode active material in supercapacitor. The semiconductive properties of Bi 2 S 3 resulted in exceptional capacitive behavior. Bismuth sulfide synthesized at 75°C exhibited a specific capacitance of 457 F g −1 at 1 A g −1 in 6 mol L −1 KOH solution as an electrolyte. Moreover, material prepared at 75°C maintained the best capacitance value at a large current density of 20 A g −1 , compared with bismuth sulfides synthesized at the temperatures of 0°C and 25°C.
