“…Many efforts have been directed toward studies on piezocatalysis, such as piezoelectric materials can be divided into chalcogenides, perovskites, bismuth-based piezoelectric materials, and others. In particular, molybdenum disulfide (MoS 2 ) has been widely investigated owing to acknowledged piezoelectric properties as well as high activity, low cost, elemental abundance, and good mechanical and chemical stability. , MoS 2 exhibits piezoelectric effects due to its noncentrosymmetric structure and can be polarized under low mechanical forces. However, the actual piezoelectric coefficient of MoS 2 is unsatisfactory while the utilization rate of mechanical energy is less than 30% .…”
