Abstract

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 (^•O₂¯) and hydroxyl radical (^•OH) evolution. In addition, the piezoelectric degradation mechanism of pollutant dye had also been investigated in detail.
