PROBLEM TO BE SOLVED: To provide a manufacturing method of cuprous oxide using activated carbon less expensive than a single-layer carbon nanotube.SOLUTION: A manufacturing method of cuprous oxide includes a first step for having activated carbon adsorb copper acetate in a liquid phase, a second step for deaerating the activated carbon adsorbing copper of the copper acetate under a vacuum heated condition, a third step for having the activated carbon deaerated under the vacuum heated condition adsorb steam of a saturation vapor pressure, and a fourth step for irradiating the activated carbon with visible light. The method is characterized in that the visible light has the wavelength range of 500-530 nm, and the first-third steps are practiced under an environment where the light of a wavelength of 500-530 nm is removed, and that an average diameter of pores formed in the activated carbon is 1 nm or less. 【課題】単層カーボンナノチューブよりも安価な活性炭を用いて亜酸化銅を製造する方法を提供する。【解決手段】活性炭に酢酸銅を液相で吸着させる第１の工程と、酢酸銅の銅を吸着させた活性炭を真空加熱脱気する第２の工程と、真空加熱脱気された活性炭に対して水蒸気を飽和蒸気圧まで吸着させる第３の工程と、活性炭に可視光を照射する第４の工程とを有する亜酸化銅の製造方法とする。さらに、可視光が500〜530nmの波長域の光であること、第１〜３の工程を500〜530nmの波長の光が除去された環境下で行うこと、活性炭に形成されている微細孔の直径の平均を1nm以下としていることにも特徴を有する。【選択図】図４
