Über dieses Buch

This book provides a comprehensive overview of the chemistry of CO2 in relation to surface interactions and photocatalytic transformation by UV radiation. The first part deals with the modelling of an anatase surface, its interaction with CO2, and the spontaneous exchange of oxygen atoms between the gas and solid phases. The book then naturally transitions to the photocatalytic reduction of CO2, achieved by adding UV radiation and traces of water to the experimental system, to produce methane and CO. This photocatalytic reduction is explained in detail and the implications for planetary chemistry (specifically concerning Mars), as well as Earth’s atmospheric chemistry and global warming, are discussed.

Chapter 1. Carbon Dioxide and the Effects on Climate
Abstract
Last a few decades have witnessed a rising scientific interest in two well-known molecules—carbon dioxide and titania. The fundamental properties such as their chemistry, structure and application potential are well known. However, the main problem concerning CO2—the global change of climate—has not been dealt with yet. The ever-rising levels of carbon dioxide in the atmosphere, utilization of fossil fuels and the effects on global climate portend the need for a cleaner energy supply as well as the need to reduce the CO2 amount present in the atmosphere of our planet. Importantly, several recent discoveries have pointed out that novel materials based on TiO2 are able to solve climate change by establishing a new methane cycle-based energetics and economy.

Chapter 2. Oxygen Atoms Exchange Between Carbon Dioxide and TiO2 (Light Induced and Spontaneous)
Abstract
One of the exceptional features of CO2 is its ability to interact with solid surfaces on a common basis. This interaction takes the form of an adsorption and can be monitored by isotope labelling. Oxygen isotope-labelled CO2 added to a mineral, most importantly TiO2, exchanges its oxygen atoms with the sample and the changing isotopic composition can be monitored by high-resolution Fourier transform infrared spectroscopy.

Chapter 3. Photocatalytic Transformation of CO2 to CH4
Abstract
The photocatalytic reduction of carbon dioxide is a process that has received significant attention in the literature of the second half of the twentieth century. This chapter shows how chemical conditions and the environment can envisage various aspects of this process and explains what consequences these findings may have on the origin of methane on terrestrial planets, which is shown on the case of Mars.

Chapter 4. Additional Views on Prebiotic Molecules
Abstract
The field of the origin of life research is a relatively new but rapidly growing area of research. It is not the purpose of this book to review all scientific progress in this branch. Indeed, such book would have to be quite thicker, not to mention expensive. However, several ideas that have recently come up concerning the early Earth and life’s origins include CO2 and/or TiO2 as the main protagonists. We wish to mention to a certain extent these ideas and show that photochemistry might have played a vital role in the process by which we came to being.

Chapter 5. Applications of the CO2 Photocatalytic Reduction
Abstract
This chapter gives an overview of the state-of-the-art research progress in the topic of photocatalytic reduction of CO2 in selected areas of application. The knowledge of the practical uses of the photocatalytic reduction process may be beneficial to give the book more context and to specify its place in the plethora of work that is available to any reader.

Chapter 6. Conclusion
Abstract
In this last chapter, we summarize the findings and key points presented in this book for the convenience of the reader. This chapter is divided into sections, each describing a separate problematic discussed in this book. The topics go in the order in which they were presented in this book.
