Abstract

This study addresses the escalating issue of atmospheric CO2 emissions and climate change, exacerbated by the increased use of fossil fuels. It explores the synthesis of low-carbon alcohols as a viable method to utilize excess atmospheric CO2, meeting the growing demand for sustainable fuel alternatives. The research focuses on the challenges of activating CO2, often requiring conversion to CO via a reverse water gas shift reaction (RWGS) prior to alcohol synthesis. Through detailed case studies, this review investigates the factors influencing the catalytic efficiency of molybdenum-based (Mo-based) catalysts in alcohol synthesis from CO. Key aspects such as the addition of additives, support types, preparation methods, and the catalyst’s composition are analyzed for their impact on catalyst selectivity and activity. This comprehensive review not only highlights the critical conditions for optimizing catalytic reactions but also contributes to the development of effective strategies for reducing greenhouse gases through innovative catalytic technologies.
