METHOD FOR PREPARATION OF MOO3-PT THIN FILMS HAVING BI-LAYERED STRUCTURE BY ELECTROCHEMICAL DEPOSITION AND MOO3-PT THIN FILMS PREPARED BY THE METHOD

摘要

PURPOSE: An MoO3-Pt film and a method of manufacturing the film having a double-layer structure by electrochemical deposition are provided to save a manufacturing cost by decrease in the amount of Pt due to addition of an appropriate amount of MoO3 and increase catalytic activity and stability of an electrode. CONSTITUTION: A method of manufacturing a MoO3 film having a double-layer structure by electrochemical deposition comprises next steps. Chloroplatinic-acid electrolyte solution is manufactured. Molybdenum electrolyte solution is manufactured. After a substrate is dipped into the manufactured chloroplatinic-acid electrolyte solution, a Pt film is manufactured on the substrate through electrochemical deposition. After the Pt-film bearing substrate is dipped into the manufactured Molybdenum electrolyte solution, a double-layer structure of a MoO3-Pt film is manufactured through electrochemical deposition.
