In this invention, a heteroatom-doped carbon nanotubes is developed through a simple and scalable process using low-cost raw materials. This material is demonstrated to be an effective catalyst to drive electrochemical reduction of CO2 to value-added products such as carbon monoxide (CO), which is a valuable feedstock for a variety of chemical products and liquid fuels. The catalyst fabricated via this new method performs better than the commercially available ones on the market and is at least one order of magnitude cheaper.
The technology of electrochemical CO2 reduction not only tackles the problem of global climate change but also produces value-added products. One challenge of this technology is to develop an electrocatalyst that is efficient and selectively produces one single product (e.g. carbon monoxide). Currently, the commercially available catalysts are based on noble metals such as gold and silver that are too expensive. Therefore, there is a need for an effective and low-cost catalyst and a simple, scalable manufacturing method so that the electrochemical CO2 reduction technology can be scaled up for industrial applications.
