“…Different transition metal-doped bismuth sulfide nanoparticles have been reported. Anasane and Ameta reported manganese (Mn 2+ ) doped Bi 2 S 3 nanoparticles of different morphologies [ 16 ]. A simple synthesis of Eu-doped Bi 2 S 3 nanoparticles, in various ratios, through the breakdown of dual single source precursors: Bi(III) dithiocarboxylate and Eu(III) dithiocarboxylate complexes has been described [ 17 , 18 ].…”

Background A large volume of dye molecules finds its way into the environment, accumulates in water bodies, and makes the aquatic system unsafe to human health. Due to the complex nature of these dye materials, most of the conventional techniques are not effective for their removal. Semiconductor photocatalysis has emerged as a promising technique for the destruction of organic pollutants under UV or visible light irradiation. Among the semiconductors, Bi2S3 is widely employed in photocatalysis due to its non-toxicity and chemical stability. However, one of its problems is the high recombination rate of the charge, and various methods have been employed to enhance the photo-reactivity. One of these methods is the incorporation of transition elements. Results Herein, a facile solvothermal method was used to prepare Bi2S3 nanorods and needle- shaped Sn doped Bi2S3, using bismuth(III) tris(N-phenyldithiocarbamate) as a single-source precursor. The prepared nanomaterials were characterized, and used as efficient photocatalyst for the photo enhanced degradation of methylene blue (MB) dye under visible light irradiation. The nanomaterials exhibited very good photocatalytic activity towards the photo degradation of MB, showing a degradation rate of up to 83% and 94% within 150 min for the pristine and Sn doped Bi2S3, respectively. Conclusion The enhancement in the photocatalytic activity of the Sn doped Bi2S3 was attributed to the suppression in the recombination rate of the electron‐hole pairs, due to the formation of new energy level below the CB, that was capable of altering the equilibrium concentration of the carrier. This confirmed that Sn doped Bi2S3 could be utilized as valuable cost-efficient catalysts for eliminating methyl blue from aqueous solutions and also possible candidates in environmental pollution treatment.

“…The photocatalytic decolorization of azo dye acid orange 7 (AO7) was investigated using as-synthesized powder under sunlight. Anasane and Ameta 18 reported morphologies of nanostructured bismuth sulphide and Mn (II) doped bismuth sulphide nanoparticles and decolorization of methyl violet using as prepared doped bismuth sulphide while Ashok et al 19 reported hydrothermal synthesis of ultraviolet-visible light responsive ruthenium doped titania (RuXTi1-XO2) nanosheet and also investigated its effect on photocatalytic degradation of reactive red dyes. In the present study, nanosized barium chromate has been prepared and it was further used to investigate the photocatalytic degradation of malachite green.…”

The photocatalytic degradation of malachite green was carried out in presence of nanosized barium chromate semiconducting powder used as a photocatalyst. The nanophotocatalyst was prepared by precipitation method and further characterized by XRD, SEM-EDS and FT-IR. The progress of the reaction was monitored spectrophotometrically. A tentative mechanism has been proposed where hydroxyl radical has been reported as an oxidizing agent for the photocatalytic degradation of the dye molecules. Some physicochemical parameters were studied, which also supported the mineralization of the dye solution.

Metal chalcogenide nanoparticles are widely used to degrade environmental pollutants. Zinc‐Bismuth Chalcogenide/Carbon (ZnBi2S4/Carbon and ZnBi2Se4/Carbon) nanocomposites were synthesized and the surface was covered with sucrose before carbonization to yield carbon nanocomposites. The solar irradiation is used to convert sucrose into carbon nanocomposites. The as‐synthesized nanocomposites were well characterized in detail in terms of their structural, morphological, functional, and optical properties. Nanocomposites are well‐known and frequently show excellent characteristics in all domains, including photocatalysis and electrochemical applications. The superior electron transfer capability, improved light harvesting, and increased catalytic active sites were said to play a crucial role in the bandgap contribution to the improved photocatalytic activity. The degradation of dyes like Methylene Blue (MB), Methyl Orange (MO), and Rhodamine B (RhB) in solution under sunlight irradiation was used to investigate the photocatalytic activities of the nanocomposites. Pseudo‐first‐order kinetic theory was followed. Specific capacitances of nanocomposites are 659.479 F/g and 871.198 F/g at 25 mV/s for ZnBi2S4/Carbon and ZnBi2Se4/Carbon nanocomposites, respectively.
