Abstract
There is provided a method of preparing a photoelectrochemical and electrochemical electrode catalyst, the method including preparing a metal oxide-based electrode, introducing a phosphate layer on a surface of the metal oxide-based electrode; and converting the phosphate layer into an oxyhydroxide layer by performing electrochemical activation on the phosphate layer. The efficiency of selective oxidation reaction of ammonia in wastewater may be improved.
