摘要： A method for producing a metal catalyst, including applying an anodic current with a positive (+) sign to form a metal oxide having a bipyramidal shape, and then applying a cathodic current with a negative (−) sign or applying a potential in a negative (−) direction to form uniform atomic scale pores on the surface and inside of the metal particles, and controlling the amount of oxygen remaining in the metal to modify the metal surface.

摘要： Disclosed is a bus stop using a large-scale perovskite solar cell in which a perovskite solar cell is prepared using a hybrid structure including a graphene-carbon nanotube. The bus stop includes a body unit fixed to the ground to maintain the overall shape, a solar cell unit for producing electrical energy from sunlight, and an energy storage system (ESS) for storing the electrical energy produced by the solar cell part.
