Photocatalytic reduction of CO2 over TiO2 based catalysts (2008, background): “The optimal photocatalytic efficiency is obtained using anatase with a small admixture of rutile (Bouras et al., 2007).”
Recent developments in environmental photocatalytic degradation of organic pollutants: the case of titanium dioxide nanoparticles—a review (2015, background): “The main aim for titania modifications is to reduce the band gap of titania thus shifting its optical response to the visible-light region and to reduce the rate of electron-hole pair recombination to increase its photoreactivity [105, 132, 180].”
Engineering TiO2 nanomaterials for CO2 conversion/solar fuels (2012, background): “The interface creates defect sites with unique adsorption and charge trapping properties that contribute to high reactivity at the interfaces [38,40,51,52].”
Incorporation of titanium dioxide nanoparticles in mortars — Influence of microstructure in the hardened state properties and photocatalytic activity (2013, background): “Several authors have tested different doping methods trying to increase the efficiency of the catalyst [35,36].”
Review of material design and reactor engineering on TiO2 photocatalysis for CO2 reduction (2015, background): “serve as an electron trap formed from the lower band gap of rutile [62].”
