Abstract: The present invention relates to a positively-charged body for a triboelectric generator and a triboelectric generator including the same. More particularly, the present invention relates to a positively-charged body based on a two-dimensional material including silicon oxide, and to a triboelectric generator including such a positively-charged body. Thus, a conventional manner in which the positively-charged body is mainly composed of a metal thin film or polymer is not used, but the positively-charged body is made of the silicon oxide and the two-dimensional material. Thus, charge generation efficiency of the generator via contact between the positively-charged body and a negatively-charged body may be dramatically enhanced.

Abstract: A method for manufacturing a charge pump-based artificial lightning generator comprises the steps of: forming a second electrode on a prepared substrate; forming a negatively charged body having a sponge structure under the second electrode; removing spherical polymer particles from the negatively charged body using a toluene solution; allowing metal particles to penetrate into the negatively charged body; forming a positively charged body in a location which is at a predetermined distance below the negatively charged body in order to generate charges; nano-structuring the surface of the positively charged body; coating the nano-structured surface of the positively charged body with second metal particles; forming a ground layer for charge separation while maintaining a constant distance in the downward direction from one side of the positively charged body; and forming a first electrode for charge accumulation in a location which is at a predetermined distance below the positively charged body.

Abstract: A water decomposition device may include a hydrogen-generating electrode including a first external electrode and at least one first internal electrode formed integrally with the first external electrode, and an oxygen-generating electrode including a second external electrode and at least one second internal electrode formed integrally with the second external electrode. The first external electrode and the second external electrode are disposed to face each other, and the first internal electrode and the second internal electrode are disposed alternately in a direction perpendicular to the longitudinal direction thereof. Therefore, the water decomposition device may secure both transparency and durability even when an opaque material is used therefor.

Abstract: Disclosed is a method of manufacturing an electrocatalyst. The method may include forming a metal layer on a substrate, treating a substrate of the metal layer, and forming a catalyst layer on the metal layer by applying potential to an aqueous deposition solution including a nickel precursor, a copper precursor, a phosphorus precursor, and an additive, in which a molar ratio of the nickel precursor to the copper precursor may be greater than about 49:1. Accordingly, the present invention has an advantage in that the process of manufacturing the electrocatalyst may be simplified.
