NITRATE REDUCTION METHOD, NITRATE REDUCTION CATALYST, NITRATE REDUCTION ELECTRODE, FUEL CELL, AND WATER TREATMENT APPARATUS

摘要

A nitrate reduction method includes the step of reducing at least one type selected from a group of nitrates and nitrites at an active site included in a defect of graphene in a reduction reaction, wherein the graphene is a reduced product of graphene oxide, and the defect of the graphene is derived from a defect of the graphene oxide.
