Excessive CO2 has been emitting from burning fossil fuels and has been leading to climate change. The transformation of CO2 to fuels and chemicals is of crucial importance for a sustainable carbon cycle and the long-term energy storage. Among many technologies, electrochemical transformation is considered particularly attractive since it can use renewable sources as energy input. This technology, although being very promising, confronts many challenges. The CO2 reduction reaction (CO2RR) can produce various products, such as carbon monoxide (CO), formic acid (HCOOH), methane (CH4), ethylene (C2H4), methanol (CH3OH) and so on, at similar standard electrode potentials. Hence, it is a big challenge to obtain satisfactory selectivity for a desired product.

Therefore, rationally designed electrocatalysts are essential to boost the CO2RR reaction and to tune the selectivity for a specific product. CuOx or CuMOx (M= Sn, Zn...) are highly potential for the CO2RR [1]. Tuning their structure and composition can easily change the selectivity for a specific product. Our previous work studied Cu-Sn bimetallic electrodes with different surface compositions and nano-architectures toward the CO2RR [2]. The ongoing work studies Cu with various oxide states for converting CO2 to tunable syngas. We are also exploring other Cu based bimetallic materials such as CuZn.
