Electro-oxidation of urea on the nickel phosphate-based nanomaterials

Abstract

Nickel phosphate nanomaterials and multi-walled carbon nanotubes (MWCNTs) supported nickel phosphate nanomaterials were prepared by simple precipitate method. The nickel phosphate nanomaterials were tested the electrochemical activity of urea oxidation by cyclic voltammetry in alkaline solution. The nickel phosphate nanomaterials showed high catalytic performance towards the electro-oxidation of urea. Moreover, MWCNTs supported nickel phosphate nanomaterials showed higher catalytic current and lower onset potential due to the large specific surface and high electrical conductivity of MWCNTs.
