Abstract: A recommendation data generation apparatus (2000) acquires material specification information (10) representing a material specification of a material (60) and physical property information (20) representing a physical property of a product (70). The recommendation data generation apparatus (2000) generates a self-organizing map (30) by using the physical property information (20). Each node on the self-organizing map (30) is assigned a position in a map space and a physical property vector representing a physical property. The recommendation data generation apparatus (2000) assigns each node a specification vector representing the material specification by using the material specification information (10). The recommendation data generation apparatus (2000) acquires target information (80) representing a desired physical property, and detects a target node to which a physical property vector matching that physical property is assigned. The recommendation data generation apparatus (2000) generates, by using the specification vector assigned to the target node, recommendation data (90) representing the material specification with which a product (70) having a desired physical property can be generated.

Abstract: The present invention provides a carbon dioxide reduction catalyst capable of reducing carbon dioxide under mild conditions, a carbon dioxide reduction method using the carbon dioxide reduction catalyst, and a carbon dioxide reduction apparatus. A metal oxide of the present invention has a spinel-type crystal structure including a metal element A, manganese, and oxygen. The A is at least one metal element selected from the group consisting of nickel and copper, a molar composition ratio of manganese to oxygen is from 1:1.8 to 1:2.2, and a molar composition ratio of the metal element A to manganese is from 1:1.7 to 1:2.3. In an X-ray diffraction pattern obtained by X-ray diffraction measurement using a Cu-Kα ray, the metal oxide has an intensity ratio (I18°/I37°) of 0.2 or more between a peak having a 2θ value in a range of from 16° to 20° (P18°) and a peak having a 2θ value in a range of from 35° to 39° (P37°).
