Synthesis and catalytic performance of hierarchical TiO 2 hollow sphere/reduced graphene oxide hybrid nanostructures

Structural, optical and photocatalytic properties of erbium (Er3+) and yttrium (Y3+) doped TiO2 thin films with remarkable self-cleaning super-hydrophilic properties

“…Such behavior has also been observed in Yb and Tm doped TiO 2 thin lms. 14 25 The Y 3+ or Er 3+ -doped TiO 2 samples were also composed of the anatase phase only.…”

Graphene nanocrystals in CO2photoreduction with H2O for fuel production

“…Among the various applications of graphene, such as photocatalytic CO 2 reduction, 104,110 water splitting, 105 dye and organic pollutant degradation, 106,107 lithium-ion batteries, 108 and antibacterial activity, 109 photocatalytic CO 2 reduction to valuable hydrocarbons via solar irradiation can serve as a solution to the total dependence on fossil fuels with its concomitant global warming.…”

An Effective Utilization of Solar Energy: Enhanced Photodegradation Efficiency of TiO2/Graphene-Based Composite

“…A rGO loading with 5% in the composite led to a higher light absorption and reactant adsorption but lower photocatalytic activity than the corresponding composites with 3% rGO loading. This is ascribed to the excessive addition of rGO, which partially shields the primary photoactive TiO 2 , and in the meantime, reduces the exposed available TiO 2 's surface-to-light irradiation [40].…”
