以剥离C3N4（氮化碳）纳米片为保护层，在水热过程中对MnCo2S4进行包覆修饰，得到C3N4/MnCo2S4复合材料。借助于C3N4纳米片的包覆保护，复合材料表现出优异的比电容和良好的循环稳定性。采用三电极体系，在6 mol/L的KOH电解液中，当扫描速率为5 mV/s时C3N4/MnCo2S4电极材料的比电容可达到565 F/g，而未包覆修饰的MnCo2S4的比电容为468 F/g。1 A/g的电流密度下，MnCo2S4、C3N4/MnCo2S4电极材料经2 000次的循环充放电测试后，比电容保持率分别为77%和83%。C3N4纳米片对泡沫镍上所生长的MnCo2S4起到保护和防剥落作用，纳米片包覆法为高比电容和良好循环稳定性的电极材料制备提供了新的技术路线。

The C3N4/MnCo2S4 composites were prepared by coating MnCo2S4 with the exfoliated C3N4（carbon nitride） nanosheets as the protective coat in the hydrothermal process.With the assistance of the coating protection of C3N4 nanosheets，the C3N4/MnCo2S4 composite showed excellent specific capacitance and good cyclic stability.The specific capacitance of C3N4/MnCo2S4 electrode materials was 565 F/g，while the capacitance of MnCo2S4 was 468 F/g at a scan rate of 5 mV/s in 6 mol/L KOH electrolyte via the three-electrode system.At the current density of 1 A/g，the specific capacitance retention of MnCo2S4 and C3N4/MnCo2S4 electrode materials was about 77% and 83% after charging and discharging for 2 000 cycles，respectively.C3N4 nanosheets could prevent MnCo2S4 from peeling off on the nickel foam.The coating method of nanosheets provided a novel technical route to prepare electrode materials with high specific capacitance and good cyclic stability.
