摘要：

The few number layers of Co doped MoS2 ultrathin nanosheets (UNs) with the thickness of 3.2 nm were successfully fabricated, which can decompose MB dye by 99% in 60 s through ultrasonic wave vibration in dark. Co doped MoS2 UNs (Co-MoS2-0.10) exhibited the higher piezoelectric catalytic performance than that of its counterparts. Moreover, to verify the enhanced piezoelectric catalytic activity of MoS2 via doping effect, molecular oxygen activation properties are monitored by superoxide radical (O-center dot(2)-) and hydroxyl radical ((OH)-O-center dot) evolution. In addition, the piezoelectric degradation mechanism of pollutant dye had also been investigated in detail.
