Abstract

Honeycomb-like Ni@C composite nanostructures have been successfully prepared via a simple two-step solution route. Homogeneous Ni nanospheres with an average diameter of ∼100 nm were first obtained via a DMF–water mixed solvothermal route; then honeycomb-like Ni@C composite nanostructures were prepared through the hydrothermal carbonization of glucose solutions with suitable amounts of Ni nanospheres. The as-obtained products were characterized by XRD, SEM, TEM, ED, EDS and Raman spectroscopy. It was found that the as-obtained honeycomb-like Ni@C composite nanostructures showed good electrochemical properties and could be used as an electrochemical sensor for the detection of glucose molecules. Furthermore, the honeycomb-like Ni@C composite nanostructures presented good capacities for selective adsorption of Pb2+, Cd2+ and Cu2+ ions in water, and could be easily separated from water and reused.
