Abstract
The present disclosure relates to a reducing method of carbon dioxide using sunlight and hydrogen, and an apparatus therefor.
Claims20
A reducing method of carbon dioxide using sunlight and hydrogen, comprising:
- loading a composite catalyst containing a metal, a metal compound, and a photosensitizer into a reactor;
- injecting a gas containing hydrogen gas and carbon dioxide gas into the reactor to react the hydrogen gas with the carbon dioxide gas under sunlight irradiation.
A reaction apparatus for reducing carbon dioxide using sunlight and hydrogen, comprising:
- a reactor including a light transmission member on at least one side;
- and
- a hydrogen gas supplying member, a carbon dioxide gas supplying member, and a product outlet member which are connected to the reactor,
- wherein hydrogen gas is supplied to the reactor through the hydrogen gas supplying member, carbon dioxide gas is supplied to the reactor through the carbon dioxide gas supplying member, and sunlight is irradiated to the reactor through the light transmission member in the presence of a composite catalyst containing a metal, a metal compound, and a photosensitizer loaded into the reactor so that the hydrogen gas and the carbon dioxide gas are reacted.
