Novel Synthesis of Nanoporous Nickel Oxide and Nickel Nanoparticles/Amorphous Carbon Composites Using Soluble Starch as the Template

摘要

A simple and green synthetic route based on the use of soluble starch as the template has been utilized to prepare novel Ni(OH)_2/starch precursors.Nanoporous nickel oxide (NiO) and nickel nanoparticles/amorphous carbon (Ni/C) composites have been successfully prepared by thermal decomposition of the novel Ni(OH)_2/starch precursors in air and in nitrogen,respectively.N_2 adsorption-desorption measurements show the two final products having nanoporous structures.The electrochemical measurements indicate that the nanoporous NiO sample has a favorable faradaic pseudocapacitance behavior.
