The Electrochemical Syntheses And Characterizations Of Nickel Nanoparticles And Zinc-Nickel Nanoalloy On Composite Graphite Substrate [QD1-999].

Abstract

Nanohablur nikel (Ni) dengan purata saiz 9.7 ± 2.3 nm dimendapkan ke atas komposit elektrod grafit daripada larutan saduran 5.0 mM NiCl2.6H2O dan 1.0 M NH4Cl menggunakan kadar imbasan 6500 mVs-1. The nickel (Ni) nanocrystals with an average size of 9.7 ± 2.3 nm were deposited onto composite graphite electrode from a plating solution of 5.0 mM NiCl2.6H2O and 1.0 M NH4Cl using scan rate of 6500 mVs-1. The initial potential −1.5 V vs. Ag/AgCl, final potential −0.5 V and applied time 120 s were used for the whole deposition process.
