| 摘要 | To further apply MoS2 as a promising non-noble catalyst for addressing environmental issues, its catalytic ability must be improved. As a result of the hetero-atom doping effect and varied structure phase of MoS2, we demonstrated excellent piezocatalysis for the degradation of methylene blue (MB) dye under stirring/ultrasonic catalyzed by MoS2. Compared with pristine MoS2 and O-doping MoS2 (O-MoS2), O-MoS2& reduced graphene oxide (O-MoS2&rGO) exhibits enhanced piezocatalytic activity. When the initial concentration of MB solution is <= 15 mg L-1, both stirring and ultrasonication can make the optimal O-MoS2&rGO composite to degrade the dye completely within 20 min. The experimental results have led to the proposal of a mechanism that elucidates the enhancement effect of rGO and O doping on the piezocatalytic performance of MoS2. This study highlights the significance of constructing heterostructure interfaces and the impact of hetero-atom doping on the promotion of piezocatalysis efficiency. |
