ABSTRACTThe solid-gas phase photoassisted reduction of carbon dioxide (artificial photosynthesis) was performed using ferroelectric lithium niobate and titanium dioxide as photocatalysts. Illumination with a high pressure mercury lamp and visible sunlight showed lithium niobate achieved unexpectedly high conversion of CO2 to products despite the low levels of band gap light available and outperformed titanium dioxide under the conditions used. The high reaction efficiency of lithium niobate is explained due to its strong remnant polarization (70 μC/cm2) thought to allow longer lifetime of photo induced carriers as well as an alternative reaction pathway.

Photocatalytic Processes

Both solar water splitting and carbon dioxide reduction using semiconductor systems have been studied as important components of artificial photosynthesis. This paper describes the various photovoltaic-powered electrochemical, photoelectrochemical and photocatalytic processes. An overview of the state-of-the-art is presented along with a summary of recent research approaches. A concept developed by our own research group in which fixed particulate photocatalysts are applied to scalable solar water splitting is discussed. Finally, a description of a possible artificial photosynthesis plant is presented, along with a discussion of the economic aspects of operating such a plant and potential reactor designs.

Addressing the three major stresses facing our planet, clean air, clean energy, and clean water, is within our reach. At present, new materials such as metal-organic frameworks and covalent organic frameworks, produced by reticular chemistry, are at the forefront of efforts to capture carbon dioxide from air and harvest water from air. We envision that the products of these two capture processes (carbon dioxide and water) can be fed into a conversion cycle in which they are used to produce fuels and chemicals via artificial photosynthesis. The use of air as a nonpolluting, cyclable, and sustainable resource for carbon and water can be powered by sunlight. We describe how the scientific basis for realizing this vision is either already achieved or being established, and that in the fullness of time this paradigm may lead to new global industries and a thriving “air economy.”
