Abstract: A catalyst for synthesizing hydrogen peroxide is provided. The catalyst includes first material capable of dissociating hydrogen molecules; and second material capable of suppressing dissociation of oxygen molecules, where one or more interfaces are formed between the first material and the second material. The catalyst can be used as an alternative to the expensive palladium catalysts. In particular, the catalyst can be used for the direct synthesis of hydrogen peroxide.

Abstract: A method, performed by an electronic device, of predicting an electronic structure of a material includes: receiving input data of a user related to elements constituting the first material; applying the received input data to a trained model for estimating a density of state of the first material; and outputting a first graph indicating the density of state for each energy level of the first material output from the trained model, wherein the trained model is trained to generate the first graph based on pre-input data about a plurality of second materials composed of at least some of the elements constituting the first material and a plurality of second graphs representing the density of state for each energy level of the plurality of second materials.
