Thermal, electrochemical, and photochemical conversion of CO2 to fuels and value-added products

This review compares various alternate fuels and value-added products from conversion of carbon dioxide such as simple molecules to higher hydrocarbon fuels and polymers. Different methods of activation are summarized that lead to different products. We summarize the advantages and disadvantages of different methods of conversion of carbon dioxide. An overall summary is given at the end of the review that discusses future approaches and promising approaches.
