“…Matějová et al (2013) prepared gold-enriched TiO 2 and TiO 2 -ZrO 2 , and the performance of photocatalysts illuminated by UV lamp with the wavelength maximum at 254 nm was decreasing in the order TiO 2 -ZrO 2 [ Au/TiO 2 -ZrO 2 [ TiO 2 [ Au/ TiO 2 [ TiO 2 Evonic P25. Deposition of silver on TiO 2 surface leads to a decrease in CO production followed by an enhancement of CH 4 , C 2 H 6 and C 3 H 7 yields (Collado et al 2013). …”

Fossil fuels are currently the major energy source and are rapidly consumed to supply the increasing energy demands of mankind. CO 2 , a product of fossil fuel combustion, leads to climate change and will have a serious impact on our environment. There is an increasing need to mitigate CO 2 emissions using carbon-neutral energy sources. Therefore, research activities are devoted to CO 2 capture, storage and utilization. For instance, photocatalytic reduction of CO 2 into hydrocarbon fuels is a promising avenue to recycle carbon dioxide. Here we review the present status of the emission and utilization of CO 2 . Then we review the photocatalytic conversion of CO 2 by TiO 2 , modified TiO 2 and non-titanium metal oxides. Finally, the challenges and prospects for further development of CO 2 photocatalytic reduction are presented.

“…Other semiconductor oxides, such as ZnO, are also active for the photocatalytic reduction of CO 2 in the gas phase producing mainly CO and CH 4 , although the efficiency is poor compared to TiO 2 [38]. More recently, mesoporous Fe-doped CeO 2 materials have proved to be very promising alternative photocatalysts for this application.…”

“…Accordingly, they have a wide range of potential applications in solar cells, visible-light-responsive photocatalysis, and light-emitting diodes [50]. The nanoparticles in an SPR state are excited [38] when photons of a specific wavelength, which varies with the metal and the particle dimensions and the morphology, impinge on the material, and this process causes the plasma of conduction electrons to oscillate collectively. One consequence of photoactivating the localized SPR is the generation of locally enhanced electromagnetic (EM) fields at the nanomaterial's surface.…”

The possibility of producing fuels and chemicals from CO 2 using semiconductors and sunlight holds the promise of storing abundant, despite diluted, solar power in the form of energy-rich chemicals. In principle, this process can operate under very soft conditions, and this may facilitate a distributed production of solar fuels. However, photocatalytic reduction of CO 2 over semiconductors has proved to be a very challenging process, and the yields currently attained are rather limited. Accordingly, a number of drawbacks should be overcome if this process is expected to become a feasible alternative for generation of sustainable fuels and chemicals in the midterm. First, the conversion rate of CO 2 should be boosted to reach values in the order of millimoles per hour and gram of semiconductor. In addition, several relevant engineering challenges should be conveniently solved before this technology becomes viable. In this chapter, we evaluate thoroughly the most recent advances on the understanding of this photocatalytic process, and at the same time, we try to define the most relevant aspects that scientific research should address in the near future.
