A New Photocatalyst Speeds up the Conversion of Carbon Dioxide into Methane
Photocatalyst Speeds up the Conversion of Carbon Dioxide into Methane
- A new oxygen-deficient titanium dioxide (TiO2-x)prepared with Mg reduction method drastically improves the CO2 conversion efficiency up to three times the efficiency of existing photocatalyst.
- It is expected to be applied for carbon dioxide resources and reduction technology.
DGIST’s joint research team has developed a new titania photocatalyst that converts carbon dioxide (CO2) into methane three times more efficiently than the existing photocatalyst by manipulating its surface.
Carbon dioxide is a major cause of global warming. Therefore, in order to control atmostpheric carbon dioxide concentration, many countries are actively working on numerous studies to investigate effective ways to transform carbon dioxide into chemical fuels such as methane, ethane and methanol. In particular, a high-efficiency photocatalyst is essential to help prevent the generation of secondary harmful substances when converting carbon dioxide into chemical fuels.
