Method of decomposing carbon dioxide and method of forming carbon-particle structure

摘要

A method for realizing carbon dioxide reduction, which is a task to be urgently accomplished from the viewpoint of global environmental problems, is provided. The method includes the steps of irradiating carbon dioxide in a supercritical or subcritical state (i.e., near the critical point) with a UV-wavelength laser beam to decompose carbon dioxide and form a carbon-particle structure.
