Narrow band gap materials, such as Tin Selenide (SnSe), have gained attention in photocatalysis due to their ability to respond to visible light, unlike wide band semiconductors that are limited to ultraviolet light. In this study, SnSe nanoparticles (NPs) have been synthesized via hydrothermal method at low temperature (100 °C). The synthesized SnSe nanoparticles have been employed for the photocatalytic degradation of methylene blue dye. X-ray diffraction studies reveal the growth of SnSe NPs exhibiting the orthorhombic phase at a reaction time of 24 h. Field emission scanning electron microscopy (FESEM) images reveal sheet and flower-like structures that enhance the photodegradation of methylene blue dye. The degradation process was studied using a UV-visible spectrophotometer by measuring the absorbance spectra of the methylene blue solution at different irradiation times.

摘要

Narrow band gap materials, such as Tin Selenide (SnSe), have gained attention in photocatalysis due to their ability to respond to visible light, unlike wide band semiconductors that are limited to ultraviolet light. In this study, SnSe nanoparticles (NPs) have been synthesized via hydrothermal method at low temperature (100 °C). The synthesized SnSe nanoparticles have been employed for the photocatalytic degradation of methylene blue dye. X-ray diffraction studies reveal the growth of SnSe NPs exhibiting the orthorhombic phase at a reaction time of 24 h. Field emission scanning electron microscopy (FESEM) images reveal sheet and flower-like structures that enhance the photodegradation of methylene blue dye. The degradation process was studied using a UV-visible spectrophotometer by measuring the absorbance spectra of the methylene blue solution at different irradiation times.
