MoS2/MoOx nanostructures were grown on activated carbon cloth through a facile one‐step microwave‐assisted hydrothermal method. The growth of MoS2/MoOx on activated carbon cloth creates a unique structure that favors ion intercalation. The conductive activated carbon cloth, MoO3−x, and monoclinic MoO2 provide fast electron transport, whereas the MoS2 nanosheets/MoO3−x nanoparticles structure improves the capacitance. As a result, MoS2/MoOx‐nanostructure‐decorated activated carbon cloth shows a high specific capacitance of 230 F g−1 at a scan rate of 5 mV s−1 with a low contact resistance of approximately 1.91 Ω. Moreover, the activated carbon cloth acts as a template for the growth of a perpendicular MoS2 layer, which gives an excellent utilization rate of the active MoS2/MoOx material. We also demonstrate that the MoS2/MoOx/activated carbon cloth nanocomposite shows excellent electrochemical stability with retention up to 128 % after 1500 cycles. Finally, we show the use of a microwave‐assisted hydrothermal method for the synthesis of the MoS2/MoOx/activated carbon cloth nanocomposite as an alternative and clean route to improve the kinetics of the intercalation redox reaction.

MoS2 / MoOx纳米结构修饰的活性炭布可增强超级电容器性能

MoS 2 / MoO x纳米结构通过一种简便的微波辅助水热法在活性炭布上生长。MoS 2 / MoO x在活性炭布上的生长产生了独特的结构,有利于离子嵌入。导电活性炭布,MoO 3- x和单斜晶MoO 2提供快速的电子传输,而MoS 2纳米片/ MoO 3- x纳米颗粒结构提高了电容。结果,MoS 2 / MoO x纳米结构修饰的活性炭布显示出230 F g -1的高比电容扫描速率为5 mV s -1时,接触电阻约为1.91Ω。此外,活性炭布充当垂直MoS 2层的生长的模板,这赋予了活性MoS 2 / MoO x材料极好的利用率。我们还证明了MoS 2 / MoO x /活性炭布纳米复合材料表现出出色的电化学稳定性,在1500次循环后保留率高达128%。最后,我们展示了使用微波辅助水热法合成MoS 2 / MoO x/活性炭布纳米复合材料作为替代和清洁途径,可改善插层氧化还原反应的动力学。
