Abstract

We proposed the synthesis of MoP/MoO₂/carbon nanotube (MoP/MoO₂/CNT) through a simple and ultrafast microwave strategy. After phosphating, the conductivity and electrochemical activity of the nanocomposites were significantly increased, and charge storage was accelerated. The MoP/MoO₂/CNT electrode was a novel supercapacitor electrode material with a specific capacitance of up to 447.6 F g⁻¹ at a current density of 1 A g⁻¹, maintaining a stable cycle life at 86.5% of the initial capacitance after 10,000 cycles. Moreover, the asymmetric supercapacitor (ASC) with MoP/MoO₂/CNT and AC (activated carbon) are a positive electrode and negative electrode, respectively, with an energy density of 31.6 Wh kg⁻¹ and a power density of 190 W kg⁻¹. The MoP/MoO₂/CNT nanocomposite was a potential electrode material for future applications due to its outstanding properties, especially in the field of industrial convenient and rapid synthesis of electrode materials.

摘要

我们提出了通过简单且超快的微波策略合成MoP / MoO ₂ /碳纳米管（MoP / MoO ₂ / CNT）。磷化后，纳米复合材料的电导率和电化学活性显着提高，并加速了电荷存储。MoP / MoO ₂ / CNT电极是一种新型超级电容器电极材料，在1 A g ^-1的电流密度下，比电容高达447.6 F g ^-1，在此之后的初始电容保持86.5％的稳定循环寿命10,000个周期。此外，具有MoP / MoO ₂的非对称超级电容器（ASC）/ CNT和AC（活性炭）分别是能量密度为31.6 Wh kg ^-1和功率密度为190 W kg ^-1的正极和负极。MoP / MoO ₂ / CNT纳米复合材料因其优异的性能而成为未来应用的潜在电极材料，特别是在工业上方便且快速合成电极材料的领域。
