Large-scale synthesis of Cu2O nanocubes and their electrochemical properties

Abstract

As an environmentally-friendly p-type semiconductor, cuprous oxide (Cu2O) has exhibited potential applications, in particular sensors, solar cells, and Li-ion batteries. In this paper, uniform Cu2O nanocubes were large-scale fabricated through a solution-based chemical precipitation method. The as-synthesized products were characterized by XRD and SEM. As anode materials for Li-ion batteries, Cu2O nanocubes show excellent cycling performance, high capacity retention and coulombic efficiency.
