“…Some references have reported that Bi 2 S 3 is an n-type semiconductor [8] with direct band gap 1.30 eV at 300 K and 1.45 eV at 77K. Temperature dependence of the band gap of Bi 2 S 3 in the temperature range T = 77-300 K is dE g /dT = -8 × 10 -4 eV/K and its extrapolated band gap to 0K is 1.0 eV [1,2,4,[8][9][10][11][12]. The earlier reported, band gaps are in the range 1.30-1.70 eV and show the band gap depends on the crystal size [13][14][15][16][17].…”

Photocatalysis technology has been wildly used to remove the most pollutants for environmental remediation under light irradiation. This chapter summarized the applications of BiOX (X = Cl, Br, and I) photocatalysts, including synthesis, photocatalytic performance without modification, enhanced VLD photocatalytic activity with the modification, and photocatalytic stability. Photocatalytic degradation (PCD) removal of volatile organic compounds (VOCs), contaminated chemicals, organic pollutants, and biological substances were introduced in this chapter. On the other hand, the morphologies, bismuth-rich effects, facet effects, and photocatalytic mechanisms of BiOX were discussed to provide effective methods for designing highly visible-light-driven (VLD) photocatalytic activity BiOX photocatalysts. The unsatisfactory points and future research directions also were briefly discussed at the end.

“…Bismuth sulfide (Bi2S3) nanoparticles can be used in various fields such as thermoelectric devices [6], photovoltaics [7], nonlinear absorption [8], biomolecule detection [9], photodiode array and infrared spectroscopy [10,11]. Till date various morphologies of Bi2S3 such as nanorods [12], nanoparticles [13], nanowires and nanoflowers [14], have been synthesized by using a variety of methods such as hydrothermal route [15], precipitation [16], and microwave irradiation [17]. Development of simple, effective and template-free methods for fabricating Bi2S3 nanostructure is of great importance to nanotechnology and remains a key research challenge.…”

One dimensional Bi2S3 nanorods have been successfully synthesized by a very simple reflux method with different precursor concentration for 2 hours at 180 �C. The as-synthesized Bi2S3 powders were characterized by X-ray diffraction (XRD), high resolution scanning electron microscope (HRSEM), high resolution transmission microscope (HRTEM), UV-Vis spectrometer, Fourier transform infrared (FTIR) spectrometer. X-ray diffraction (XRD) results show that the resulting nanocrystals have an orthorhombic structure. X-ray diffraction patterns indicate a polycrystalline nature and the crystallite sizes seem increase with increase in the concentration. The HRSEM and HRTEM images reveal that the diameter of the nanorods increase with increasing concentration of the precursor. Morphological analysis reveals that the as-prepared Bi2S3 nanorods can be tuned to morphology by varying precursor concentration from 0.01 M to 0.001 M. The bismuth nitrate, which is known to be a linear polymer, plays a critical role as a precursor and a template for the growth of uniform Bi2S3 nanorods. Bi2S3 nanorods are good absorbents of solar radiation and hence can be used in solar cells.
