Abstract: A carbon-based material according to the present invention contains dopant atoms of metal and non-metal such as nitrogen. In a radial distribution function obtained by Fourier transform of a K-edge EXAFS of the metal, a ratio of “A” to “B” is equal to or more than 4.0, wherein “A” denotes an intensity of the highest one of peaks around a distance equal to a coordinate bond length between atoms of the metal and the non-metal and “B” denotes an intensity of the highest one of peaks around a distance equal to a metallic bond length between atoms of the metal. Note that when the metal is platinum, in a radial distribution function obtained by Fourier transform of an LIII-edge EXAFS of the platinum, a ratio of “A” to “B” is equal to or more than 4.0.
Abstract translation: 根据本发明的碳基材料含有金属和非金属如氮的掺杂剂原子。 在通过金属的K边缘EXAFS的傅里叶变换获得的径向分布函数中，“A”与“B”的比例等于或大于4.0，其中“A”表示峰的最高值的强度 大约等于金属和非金属的原子之间的坐标键长度的距离，“B”表示等于金属原子之间的金属键长度的距离中最高的一个峰的强度。 注意，当金属是铂时，在通过铂的LIII边缘EXAFS的傅里叶变换获得的径向分布函数中，“A”与“B”的比等于或大于4.0。

Abstract: A purification unit includes a first electric conductor, a second electric conductor, and a third electric conductor. At least a part of the first electric conductor is electrically connected to one surface of the third electric conductor, and at least a part of the second electric conductor is electrically connected to the other surface of the third electric conductor. At least a part of the first electric conductor contacts a gas phase including oxygen, and at least a part of the second electric conductor contacts a treatment target. A purification device includes the purification unit, and a treatment tank for holding, in an inside, the purification unit and wastewater to be purified by the purification unit. The purification unit is installed so at least a part of the first electric conductor contacts the gas phase, and at least a part of the second electric conductor contacts the wastewater.

Abstract: A purification unit includes a first electric conductor and a second electric conductor that contacts the first electric conductor. The first electric conductor includes a junction composed of a contact surface with the second electric conductor and an electronic connection section that conducts electrons from the junction to a catalyst. The second electric conductor includes a junction composed of a contact surface with the first electric conductor and an electronic connection section that conducts electrons, which moves from microorganisms to the second electric conductor, to the junction. The electronic connection section of the first electric conductor has higher electrical resistivity than the junction of the first electric conductor, and/or the electronic connection section of the second electric conductor has higher electrical resistivity than the junction of the second electric conductor. The first electric conductor contacts a gas phase including oxygen, and the second electric conductor contacts a treatment target.
