WebAs seen in Fig. 6 C, Bi 2 S 3 has a narrow indirect band gap around 1.3–1.7 eV ( Deng and Zhao, 2024 ), which has been related to VB top position and conduction bad bottom edge. That means that Bi 2 S 3 has high absorption at the near-infrared region (NIR) which corresponds to 50% of the sunlight spectrum.
WebThe band gap of tungsten oxide (sample W0) was estimated as 2.97 eV. Therefore, it is obvious from the data that increasing the content of tungsten over bismuth resulted in a “blue” shift of the band gap towards the UV range. The band gap of the titanium dioxide sample was considerably higher, compared to the values obtained for the bismuth ... WebBismuth molybdate is an Aurivillius oxide with formula Bi2MoO6; it is well described in the literature due to its interesting physical and chemical properties. It finds applications as a gas sensor [10], dielectric, and has recently been reported as an efficient visible light-activated photocatalyst [11].
