Through electrocatalytic carbon dioxide conversion, renewable clean electric energy such as wind power generation and solar power generation is used as energy, and carbon dioxide is directly converted into fuels and chemicals such as carbon monoxide and formic acid at normal temperature and pressure, and at the same time, carbon dioxide resource utilization and effective storage of clean electric energy are realized.
It is reported that after nearly two years of exploration, the Chinese Academy of Sciences found that the Pd-Sn alloy catalyst composed of metal palladium (PD) and tin (Sn) has excellent performance. Only by applying a very low voltage can 99% of the input electric energy (current efficiency) be used to drive carbon dioxide into formic acid.
Formic acid is a basic organic chemical raw material, which is widely used in pesticide, leather, dye, medicine and rubber industries.
Direct production of ethanol from carbon dioxide based on electrocatalysis of nitrogen-containing mesoporous carbon
In addition, the team also developed nitrogen-doped mesoporous carbon (N-carbon) materials for electrocatalytic carbon dioxide conversion. The direct conversion of carbon dioxide into ethanol was successfully realized by adjusting the pore structure and surface active site configuration of carbon.
Ethanol is one of the most widely used basic chemicals, which is used to synthesize acetic acid, beverages, spices, dyes, fuels and so on.
