A new electrocatalyst called a-CuTi@Cu converts carbon dioxide (CO2) into liquid fuels. As reported by a team of Chinese researchers in the journal Angewandte Chemie, active copper centered on an amorphous copper/titanium alloy produces ethanol, acetone, and n-butanol with high efficiency.
Most of our global energy demands are still being met by burning fossil fuels, which contributes to the greenhouse effect through the release of CO2 . To reduce global warming, we must look for opportunities to use CO2 as a raw material for basic chemicals. Through electrocatalytic conversion of CO2 using renewable energy, a climate-neutral, artificial carbon cycle could be established. Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO2. These could then be burned as needed. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport. However, the electrocatalytic formation of products with two or more carbon atoms (C2+) is very challenging.
A team from Foshan University (Foshan, Guangdong), the University of Science and Technology of China (Hefei, Anhui), and Xi’an Shiyou University (Xi’an, Shaanxi), led by Fei Hu, Tingting Kong, Jun Jiang, and Yujie Xiong has now developed a novel electrocatalyst that efficiently converts CO2 to liquid fuels with multiple carbon atoms (C2–4). The primary products are ethanol, acetone, and n-butanol.
