MANUFACTURING METHOD FOR PHTOELECTRO CHEMICAL CELL PHOTOANODE WITH DISPERSED PLASMON METAL NANO PARTICLES AND THE PHTOELECTRO CHEMICAL CELL PHOTONAODE

摘要

The present invention is a plasmon metal nanoparticle that improves the water oxidation properties of scheelite monoclinic bismuth vanadate (BiVO ₄ ) so that it can be used as a photoelectrochemical cell (PEC) photoanode. It relates to a photoelectrochemical cell photoanode manufacturing method and a photoelectrochemical cell photoanode manufactured by the photoelectrochemical cell photoanode manufacturing method. The method for manufacturing a photoanode of a photoelectrochemical cell decorated with plasmon metal nanoparticles of the present invention as described above includes: forming a metal oxide nanowire layer on a substrate; Forming a photosensitive material layer by coating a photosensitive material nanoparticle solution on the metal oxide nanowire layer to form a photosensitive material/metal oxide nanowire heterostructure; And applying a nanoparticle solution containing a metal nanoparticle precursor and a reducing agent on the photosensitive material/metal oxide nanowire heterostructure to attach metal nanoparticles, and in the step of attaching the metal nanoparticles, The photosensitive material is prevented from melting during the process of attaching the metal nanoparticles by adjusting the pH of the nanoparticle solution.
