The depletion of increasing CO2 of the atmosphere and the generation of alternate fuel sources are among the biggest challenges being faced by the scientific community across the globe. This scenario has propelled work in the direction of utilization of CO2 by various methods. Electrochemical reduction of CO2 is one of the leading research areas that may be useful not only for the utilization of CO2 but also for the generation of green fuels and storage of renewable energy (solar or wind). However, the process is kinetically impeded and less selective toward a specific product and, therefore, requires efficient electrocatalysts. Much work has already been done in this field, and significant success has also been achieved. Hence, in this review paper, the potential of electrochemical reduction of CO2 for fuel generation is discussed, with special focus on electrocatalysts. The suitability of different electrocatalysts is addressed along with the possible scope for enhancing the efficiency of the process.

SUMMARY

In this review, the electrochemical reduction of CO2 was discussed for the synthesis of green fuels with special reference to the cathode electrocatalyst. Enough possibilities for CO, HC and alcohol product formation were found. It was seen that the metal oxides were less prone to poisoning as compared to the metal electrocatalysts. Hydrogen, an ERC by-product, may also be well utilized for the production of syn-gas. However, more research is required for increasing Faradaic efficiency of products formation. Furthermore, research in the field of CO2 capture and renewable energy storage will also help to maximize the utilization of this process. In view of all these facts, it was found that besides having so many challenges, the electrochemical reduction of CO2 has ample scope for improvement.
