Greenhouse gases mitigation is one of most important challenges facing societies nowadays. Therefore, the way to reduce greenhouse gas emissions should be using carbon free sources that do not generate extra CO 2 to the atmosphere. However, there is a great potential in energy carriers and other materials from CO 2 , with many challenges to overcome. It has been suggested that the reduction of CO 2 and conversion to renewable fuels and valuable chemicals may be considered as a promising solution to reduce the greenhouse gas emissions. This chapter discusses the recent developments and remaining challenges of CO 2 utilization for the efficient production of methanol. This includes novel technologies, approaches, and current barriers for the conversion of CO 2 to methanol through heterogeneous catalysis, homogenous catalysis, electrochemical, photochemical, and photoelectrochemical conversion, which will contribute to the economic growth and mitigate the hazardous emissions for cleaner environment. A review of various stateof-the-art technologies for CO 2 conversion to methanol was carried out aiming to establish the advances in this area and present an overview of the recent research trend for future development of new ideas for CO 2 reduction into methanol in a large scale.

Abstract

The rising atmospheric levels of carbon dioxide is one of the most urgent challenges facing societies nowadays. There is also great potential in energy carriers and other materials from CO 2 , with many challenges to overcome. The way to reduce greenhouse gas emissions should be using carbon free sources that do not generate carbon dioxide to the atmosphere. This article reviews recent developments, remaining challenges and novel approaches of CO 2 reduction for the efficient and sustainable production of fuels and valuable chemicals. It has been suggested that the CO 2 reduction and conversion may provide promising solutions for energy resource scarcity as well as reduction of greenhouse gas emissions. Hence, this paper discusses novel technologies and approaches to reduce carbon dioxide to produce energy and chemicals through heterogeneous catalysis, electrocatalysis and photocatalysis, which will contribute to the economic growth and mitigate the hazardous emissions for cleaner environment. A review of the state-of-the-art of various technologies for carbon dioxide reduction was carried out aiming to demonstrate the advances in this area and provide an overview of the research trend for future development of new ideas for CO 2 reduction in a large scale.
