Synthesis of Co2P Nanostructure via Microwave Hydrothermal Method and Its Electrochemical Properties

One-dimensional Co2P nanowires were synthesized by microwave hydrothermal (MWH) method using CoCl2 center dot 6H(2)O and yellow phosphorus as raw materials, and CTAB surfactant as a structure-directed agent. The effect of surfactants on the Co2P nanostructures was studied. As-synthesized nanowires were characterized by XRD, SEM, and TEM. The results show that one-dimensional Co2P nanostructures are synthesized with the presence of surfactants, and a number of Co2P nanowires with 50 similar to 200 nm in diameter are obtained using CTAB. The yield and length of Co2P nanowires are increased with the increase of CTAB contents. The electrochemical properties indicate that Co2P nanowires have typical pseudo-capacitive characteristics and remain capacitance retention of 68 % after 1000 cycles.
