Graphene oxide: Exploiting its unique properties toward visible-light-driven photocatalysis

Photocatalytic reduction of CO 2 with H 2 O over graphene oxide-supported oxygen-rich TiO 2 hybrid photocatalyst under visible light irradiation: Process and kinetic studies

“…Among the various renewable projects to date, the photocatalytic reduction of CO 2 into energy-bearing products has garnered interdisciplinary research attention to mitigate the evergrowing CO 2 concentration and to meet the long-term worldwide energy demands without utilizing further CO 2 -generating power resources [6][7][8][9][10][11][12][13][14][15]. In this context, photocatalysis, a wellorchestrated mimic of natural photosynthesis, for direct conversion of solar energy to chemical energy, presents an opportunity to kill these two birds with one stone [16][17][18][19]. However, the state-of-the-art technology is far from being optimal due to low overall photoconversion and selectivity [20][21][22].…”

A Metal‐Free, Nonconjugated Polymer for Solar Photocatalysis

“…[4,5] These processes frequently involve the use of strongo xidants, such as ozone, or the formation of highly reactives pecies, such as hydroxyl radicals formed in situ by the Fenton reaction or photochemically induced by photo-Fenton, [6] UV/H 2 O 2 ,o r UV/O 3 . [9] Currently,t he aim is to perform photocatalysis in the visible regiont ob enefit from the effectiveu tilization of the solar spectrum.F or this purpose, doped (e.g.,w ith transition-metal ions or noble metals) [3,10] and undoped nanometer-sized semiconductor particles or other materials, such as graphene oxide, [11] are being used for preparing photocatalysts for air and water purification. [3,7] TiO 2 is nontoxic, inexpensive, stable to irradiation, and it is able to oxidizec ontaminants effectively.…”

Insighting role of reduced graphene oxide in BiVO4 nanoparticles for improved photocatalytic hydrogen evolution and dyes degradation

“…This growth of the grain size makes the photocatalytic material more efficient for photocatalytic activity to decontaminate the water. This efficiency was observed up to 1.5% content of the rGO in BiVO 4 , but this effect is completely reversed with slight increase of the rGO in BiVO 4 that is rGO‐BiVO 4 ‐4. The phases of the crystal are completely changed to monoclinic scheelite and increased the particle size at 2% contents of rGO.…”
