THE METHOD OF PREPARATION FOR CATALYST FILM OF OXIDIZING ELECTRODE USING PHOTOELECTROCHEMICAL CELL, CATALYST FILM THEREOF AND PHOTOELECTROCHEMICAL CELL USING THE SAME

摘要

The present invention relates to a method for preparing an anode catalyst film for a photoelectrochemical cell, a catalyst film prepared according to the present invention, and a photoelectrochemical cell using the same. More particularly, in order to achieve the above object, the present invention is to disperse oxide nanoparticles. Preparing with paste or ink (step 1); Forming a coating film on another surface of the conductive substrate having one surface composed of a photoelectrode using the oxide nanoparticle paste or ink prepared in step 1 (step 2); And a method of manufacturing an anode catalyst film for a photoelectrochemical cell including a step (step 3) of performing a low temperature heat treatment of the coating film formed in step 3; A photoelectrochemical cell comprising an anode catalyst film for a photoelectrochemical cell and a photovoltaic cell / oxide / ion separator / reduction electrode, which is prepared by forming a coating film with the paste or ink on another surface of the cell and then performing heat treatment. It relates to a photoelectrochemical cell, characterized in that made of a catalyst film prepared by heat treatment after forming a coating film with an oxide nanoparticle paste or ink on one surface of the conductive substrate consisting of a photoelectrode.
