The process for fabricating photocatalytic electrodes using silenit bismuth ferrite material by electrochemical method.

Abstract

The invention proposes an electrochemical deposition process for the fabrication of photocatalytic electrodes made of bismuth ferrite silenite material (given the general formula BixFeyOz where x, y, and z are chemical ratio models. The chemical ratio models of silenite crystals vary depending on the precise chemical composition of the crystal). This process improves the quality of the silenite film with high adhesion and uniformity, and reduces the step of coating the bismuth ferrite silenite material onto the electrode after fabrication compared to traditional methods. The fabrication steps include: (a) cleaning for conductivity, (b) preparation of the electrolyte solution, (c) dissolution of the precursor, (d) preparation of the electrochemical cell, (e) electrochemical deposition, (f) washing the sample after electrochemical deposition, and (g) sample incubation.
