Piezoelectric and photocatalytic technologies use mechanical light energy to decompose environmental contaminants, demonstrating a beneficial synergistic impact. This investigation employs two-step hydrothermal-calcination technique synthesize N-doped MoS2 materials. The ideal catalyst, N-MoS2-3, utilizing the effect of piezoelectric–photocatalysis processes, attained TC degradation rate 90.8% in 60 min. kinetic constant (0.0374 min−1) is 1.75 times greater than combined rates single photocatalysis piezoelectric catalysis, indicating notable material has 80% efficiency after five cycles, its remarkable resilience. Mechanistic investigations reveal that nitrogen doping establishes an internal electric field by modulating S-Mo-S charge distribution. Photogenerated electrons move generate •O2−, while holes accumulate internally. ultrasound-induced polarization interacts with photogenerated reverse, thereby synergistically improving carrier separation facilitating redox processes. study emphasizes viability non-metal as method for modifying properties two-dimensional materials, offering novel approach enhance attributes technology possesses significant promise restoration through utilization solar energy.
