Graphene and TiO2 co-modified flower-like Bi2O2CO3: A novel multi-heterojunction photocatalyst with enhanced photocatalytic activity

Modulating the photocatalytic activity of TiO2 (P25) with lanthanum and graphene oxide

“…7) showed an increase in the emission intensity in the region of 365 393 nm, which was correlated to the La and/or GO content. This to region corresponded approximately to the bandgap energies of the photocatalysts [38].…”

Graphene in Photocatalysis: A Review

“…In another example, it was reported that the photocatalytic activity of GO–TiO 2 nanorod composite was much higher than that of GO–TiO 2 nanoparticle composite, due to the anti‐charge recombination and the more exposed (101) facets of TiO 2 nanorods . Moreover, other various nanostructured semiconductors such as 3D flower‐like, hierarchical macro‐mesoporous, inverse opal, and hollow microspheres have also been coupled with graphene to construct composite photocatalysts, all of which exhibited much higher photocatalytic activities due to their excellent morphological effect.…”

Novel Bi2O2CO3/polypyrrole/g-C3N4nanocomposites with efficient photocatalytic and nonlinear optical properties

“…Therefore, many scientists have paid much attention to how to broaden the photoabsorption region and improve the photocatalytic performance. [7][8][9][10][11][12] The conjugated polymers bearing p conjugated electron systems, such as polypyrrole (PPy) and their derivatives, have been shown great promises because of their high absorption coefficients in the visible range of the spectrum and highly efficient electron transport properties. 13,14 The conjugated structure and perfect conductivity of PPy can be useful to electron transfer during photocatalytic processes.…”
