摘要

The present invention is a three-dimensional inverse opal (Inverse Opal) three-dimensional inverse opal containing nanostructure of SnO ₂ Core (core) layer and the TiO ₂ shell (shell) layer deposited on the SnO ₂ core layer (Inverse Opal) nanostructures The present invention relates to a photoelectrode for water decomposition and a method for producing the same, wherein the photoelectrode for water decomposition of a three-dimensional inverse opal nano structure according to the present invention exhibits a three-dimensional nanowire mesh structure to maximize the active surface, (PEC) efficiency can be significantly improved by coating the TiO ₂ layer to an optimal thickness by an atomic layer deposition (ALD) method on a SnO ₂ IO film having an inverse opal nanostructure. In particular, when the TiO ₂ layer is coated with an optimal thickness on a fluorinated SnO ₂ IO film (FTO (Fluorided Tin Oxide) IO film), the PEC efficiency is further improved.
