Reduced Graphene Oxide/WO3 Nanorod Composites for Photocatalytic Degradation of Methylene Blue under Sunlight Irradiation

“…Similar kind of phenomena was also observed in earlier reported works. , Further, to quantify the crystalline quality of the prepared composites, I d / I g was calculated and it is found to be 0.6, 0.9, and 1.01 for WR1, WR2, and WR3 samples, respectively. The gradual increase in the I d / I g values in rGO/WO 3 composites signifies, during the hydrothermal reaction the average size of sp 2 domain has been decreased. ,,, …”

The methylene blue dye (MB) was used as a model dye to assess the photocatalytic degradation activity of all the prepared samples under the direct sunlight irradiation.…”

Enhancing saturable absorption in a Au-decorated MoS2/PEDOT:PSS nanocomposite through plasmon resonance and Pauli blocking

“…31 The refractive index (n) and extinction coefficient (k) of nanocomposite films can be determined by using the Kramers-Kronig relation. 32 In line with Beer-Lambert's law, the equation I = I 0 e Àat relates incident intensity (I), transmitted intensity (I 0 ), the absorption coefficient (a), and the sample's thickness (t), with each variable representing a distinct aspect of the light-absorption process. The equation a ¼ 2wk c describes the link between the extinction coefficient (k) and absorption coefficient (a), where c is the speed of light and w is the frequency.…”

Critical Review on Carbon-Based Nanomaterial for Carbon Capture: Technical Challenges, Opportunities, and Future Perspectives

“…This graphene has several unique properties, such as high optical transmittance (∼97.7%), outstanding thermal conductivity (∼5 × 10 3 W m –1 K –1 ), strong Young’s modulus (∼1.0 TPa), high intrinsic mobility of charge (2 × 10 5 ), and high theoretical surface area (2630 m 2 g –1 ).
