Hydrothermal Synthesis of rGO-TiO2 Composites as High-Performance UV Photocatalysts for Ethylparaben Degradation (2020, background): “In graphitic materials, the G band, at ~1575 cm−1, represents the perfect graphitic structure of carbon atom bonds with sp2 hybridization and is assigned to E2g-symmetry phonons of carbon atoms with sp2 hybridization [58].”
Graphene facilitated visible light photodegradation of methylene blue over titanium dioxide photocatalysts (2013, methodology): “[18] prepared a TiO2(P25)–GO composite using a simple colloidal blending method.”
Photocatalytic degradation of methyl orange dye by pristine titanium dioxide, zinc oxide, and graphene oxide nanostructures and their composites under visible light irradiation (2017, background): “While this may support the idea that graphene oxide acts as a charge carrier to reduce the amount of electron recombination, this is a relatively small improvement (Nguyen-Phan et al. 2011; Jiang et al. 2016).”
Cutting edge development on graphene derivatives modified by liquid crystal and CdS/TiO2 hybrid matrix: optoelectronics and biotechnological aspects (2020, background): “At that point, the arrangement is shifted and vacuum is used to dry the composite.([294]) It is imperative to introduce clay material between the layers of GO in the bid to modify the nanocomposite shape.”
