Title:
AMORPHOUS CARBON-METAL IRON COMPOSITE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/095801
Kind Code:
A1
Abstract:
The present invention provides an amorphous carbon-metal iron composite that is safe and easy to handle, that maintains activity for a long period of time, and that is capable of sufficiently reducing organic halogen compounds contained in soil or underground water. This amorphous carbon-metal iron composite comprises: amorphous carbon; and an iron compound including at least an α-iron phase. The carbon content of the amorphous carbon-metal iron composite is 45-75 wt%, and the total of the α-iron phase content and austenite (γ-iron) phase content of the amorphous carbon-metal iron composite is 7.5-55 wt%.
