Abstract

Abstract: An electrochemical detection of free chlorine using carbon‐metal (C−M) composite powder, with a nickel‐metal nanoparticle combined with a multilayered graphene nanoshell (Ni metal@multilayered graphene) as the main component, synthesized from CH4 via multimode microwave‐assisted catalytic decomposition, was studied. Morphological analysis of the C−M composite powder was performed by TEM–EDX and Raman spectroscopy. The C−M composite powder was packed in a porous microelectrode (PME), and its electrochemical activity with respect to free chlorine was evaluated using a potential sweep method. The C−M composite powder exhibited a sufficient activity against free chlorine. A current based on the reduction of free chlorine was observed in the potential < around+0.3 V vs. Ag/AgCl. A linear relationship was observed between the current and the concentration. Abstract :
