Converting carbon dioxide into methane or ethane selectivelyA research team led by Professor Su-Il In from Department of Energy Science and Engineering had succeeded in developing photo catalysts that can convert carbon dioxide into usable energy such as methane or ethane.As carbon dioxide emissions increase, the Earth’s temperature rises and interest in reducing carbon dioxide, the main culprit of global warming, has been increasing. In addition, the shift to reusable fuel for existing resources due to energy depletion is also drawing attention. In order to solve trans-national environmental problems, research on photocatalysts, which are essential in converting carbon dioxide and water into hydrocarbon fuels, is gaining attention.Although many semiconductor materials with large band gaps are often used in photocatalyst studies, they are limited in absorbing solar energy in various areas. Thus, photocatalyst studies focusing on improving the photocatalyst structure and surface to increase solar energy absorption areas or utilizing two-dimensional materials with excellent electron transmission are under way.Professor In’s research team developed a high-efficiency photocatalyst that can convert carbon dioxide into methane (CH4) or ethane (C2H6) by placing graphene on reduced titanium dioxide in a stable and efficient way.Read more. -- source link
