Abstract:
PURPOSE: To reduce catalysts by using non-thermal plasma instead of conventional thermal reduction method, thereby not requiring an additional heating device and reducing reduction time. CONSTITUTION: The method comprises a step of contacting non-thermal plasma state catalysts containing metal compounds with a gas containing hydrogen, where the non-thermal plasma is generated by a dielectric barrier discharge.
