A research team of Energy Science and Engineering at DGIST has succeeded in developing a titanium dioxide (TiO2)-based high efficiency photocatalyst that converts carbon dioxide to methane using a simple reduction method.

The photocatalysts developed by the research team can be used to convert carbon dioxide to fuels like methane.

Therefore, it is expected to be applied to technologies for carbon dioxide abatement and resource reclamation.

As is now well known, anthropogenic emission of greenhouse gases, particularly CO2, is a significant factor driving global climate change; sustainable, low carbon, readily portable fuels are one of the most pressing needs of modern society.

To that end, there has been a worldwide effort underway to find ways to convert carbon dioxide, a major contributor to global warming, into a usable fuel, such as hydrogen, methane, ethanol, methanol, and butanol.

In order to utilize carbon dioxide as a resource, it is essential to increase the conversion efficiency and light absorption efficiency when converting carbon dioxide into fuel, and to make photocatalyst help to prevent secondary harmful substances.
