Title:
METHOD FOR DIRECTLY CONVERTING CARBON DIOXIDE INTO SOLID CARBON BY UTILIZING PHOTOCHEMICAL REACTION
Document Type and Number:
WIPO Patent Application WO/2023/116850
Kind Code:
A1
Abstract:
A method for directly converting carbon dioxide into solid carbon by utilizing a photochemical reaction. The method comprises: placing a catalyst containing a transition metal element into a reaction device, then feeding a raw material gas containing carbon dioxide and hydrogen in a predetermined molar ratio into the reaction device, and lighting at a predetermined pressure, such that solid carbon can be formed by hydrogenating and reducing carbon dioxide by means of the photochemical reaction with carbon dioxide as a carbon source, thereby providing a new idea for resource utilization of carbon dioxide. The method is mild in condition, can be implemented at room temperature, can achieve higher carbon yield, is simple and easy in overall operation steps and wide in usability, can achieve large-scale carbon dioxide fixation and resource utilization, and has high research and application value.
