Despite its life-threatening long term effects, the continuous increase of carbon dioxide (CO2) in the environment requires immediate actions to control the accelerating climate change. An appealing solution to this problem is to utilize CO2 as feedstock to generate useful chemicals, e.g., fuel, hydrocarbons, and valuable chemicals. The chemical inertness of CO2 needs considerably large energy for its conversion into useful chemicals. Therefore, CO2 reduction reaction requires an effective catalyst for its conversion into fuel (methanol, methane) and industrial chemicals (syngas, formic acid). Recently, two-dimensional layers of early transition metal carbides and nitrides, called MXene, have shown potential for catalysis due to its exposed transition metal sites, and mechanical and chemical stability at high temperatures. Herein, the author presents the MXene as a potential heterogeneous catalyst for the CO2 reduction reaction (CRR), and the future scope in this currently developing field.

The ability to synthesize value-added chemicals directly from CO2 will be an important technological advancement for future generations. Using solar energy to drive thermodynamically uphill electrochemical reactions allows for near carbon-neutral processes that can convert CO2 into energy-rich carbon-based fuels. Here, we report on the use of inexpensive CuSn alloys to convert CO2 into CO in an acetonitrile/imidazolium-based electrolyte. Synergistic interactions between the CuSn catalyst and the imidazolium cation enables the electrocatalytic conversion of CO2 into CO at −1.65 V versus the standard calomel electrode (SCE). This catalyst system is characterized by overpotentials for CO2 reduction that are similar to more expensive Au- and Ag-based catalysts, and also shows that the efficacy of the CO2 reduction reaction can be tuned by varying the CuSn ratio.
