Enormous emissions of carbon dioxide (a greenhouse gas) produced from burning of fossil fuels, industrial revolution and rapid urbanisation originate the greenhouse effect and also ocean acidification, thereby posing a great threat to entire environment. Massive efforts have been devoted to transform carbon dioxide into useful products for sustainable development in the sectors of energy as well as environment. However, efficiently reducing the carbon dioxide is highly challenging due to higher thermodynamic stability of carbon dioxide. Among the several potentials routes possible, carbon dioxide conversion by coupling the photo and thermal energy is particularly attractive as abundant solar energy can be utilised. In this review, we provide a comprehensive overview of photo thermal carbon dioxide reduction and summarized the recent developments and clear understanding of hydrogenation of carbon dioxide by coupling the photo and thermal energy. Firstly, basic principle of coupling of solar and thermal energy is elaborated and further, discussed the current status and future challenges of implementing this strategy for carbon dioxide transformation. Ultimately, the outlook to future for reduction of carbon dioxide via coupling of photo and thermal energy is discussed.
