摘要

The present invention relates to a catalyst electrode using graphene oxide. The technical feature of the present invention is to provide a method for manufacturing a high transmission catalyst electrode based on the graphene oxide which includes a first step of making a dispersion solution by dispersing graphene oxide powder on a solvent, a second step of combining the dispersion solution on the surface of a conductive substrate, a third step of firstly drying the conductive substrate combined with the graphene oxide which is processed in the second step, a fourth step of reducing the graphene oxide combined on the surface of the conductive substrate which is processed in the third step with an electrochemical reduction method using an aqueous electrolyte, and a fifth step of secondly drying the conducive substrate which is processed in the fourth step and the catalyst electrode manufactured thereby, capable of reducing the graphene oxide at low temperatures of 150C or less. The present invention is environmentally friendly without using toxic materials and is applied to a flexible plastic substrate by adopting a low temperature process. Also, the present invention is used as a transparent catalyst electrode by obtaining high transmission and high performance which are similar to existing platinum by the improvement of a transmission rate with regard to visible rays by securing the high transmission. The present invention obtains economical effects by supplying the catalyst electrode with low costs by reducing material costs.
