Mechanically driven catalysis (MDC) has emerged as an effective strategy for environmental remediation, renewable energy conversion, and cancer therapy; this functions by converting mechanical forces to drive catalytic reactions. This review examines four primary mechanisms, namely, piezocatalysis, flexocatalysis, tribocatalysis, sonocatalysis, each involving specific pathways harnessing at the nanoscale. However, significant challenges arise in decoupling effects related individual mechanism order better understand manipulate their synergies. In review, fundamental principles underpinning MDC are systematically interpreted. Beyond mechanistic insights, recent advancements performance enhancement strategies these catalysts highlighted. Potential applications using approaches remediation (pollutant antibiotic degradation microbial disinfection), conversion (hydrogen production greenhouse gas conversion), biomedical treatments (particularly therapy) discussed. Finally, synergies limiting factors explored, addressing overlooked combined of ultrasound activation source, complexities force interactions nanoscale, need targeted application strategies. Additionally, industrial potential processes with consideration scalability practical deployment is evaluated. While remain, provides a roadmap advancing mechanically catalyst design implementation toward real-world applications, offering into its future trajectory transformative impact across numerous fields.

In this study, a contact–separation triboelectric catalytic device was designed and constructed to systematically investigate the underlying degradation mechanism. The enabled precise control of process between frictional surfaces. Polytetrafluoroethylene (PTFE) polyethylene terephthalate (PET) films were selected as pair, methylene blue (MB) used model organic pollutant. Experimental results demonstrated that in an aqueous environment effectively promotes dyes. For MB solution with initial concentration 5 mg/L, efficiency 40.34% achieved within 3 h. Moreover, exhibited excellent repeatability stability, no significant decline performance after 15 h continuous operation. Control experiments confirmed originates specifically from interaction PTFE PET Free radical quenching identified superoxide radicals (·O2−) hydroxyl (·OH) primary reactive species responsible for degradation. Based on these findings, microscopic mechanism is proposed: during contact, charging generates electrons (e−) holes (h+) surfaces; upon separation, charges interact solution—e− reduce dissolved oxygen form ·O2−, while h+ oxidize hydroxide ions (OH−) produce ·OH. combined action ·O2− ·OH ultimately efficient MB.

Herein, we first report an eco-friendly and easily retrievable piezo-responsive membrane fabricated by encapsulating chemically synthesized cobalt chromate quantum dots (CCOQDs) at varying concentrations (0%, 10%, 20%) in poly(vinylidene fluoride) (PVDF) using a facile solution-casting method. The with 10% CCOQDs (PCCO 10) exhibited high β-phase fraction (75.93%), significant dielectric constant (56.22) notable piezo-coefficient (d33= 65.1 pC/N), demonstrating strong piezocatalytic activity. It effectively generated reactive oxygen species (ROS), which reacted dye solutions, leading to 98.7% congo red (CR), 89.9% methylene blue (MB), 87% mixed (1:1 of CR MB) degradation within 50 min soft ultrasonic stimulation, primarily due •OH radicals, as confirmed scavenger trapping experiments. Additionally, the removed 81.98% total organic carbon (TOC) 75 min. Optimization alkaline pH solution, 60 W power, 1 ppm concentration enhanced its catalytic efficiency, selectivity, stability. Real-world testing on drinking wastewater showed efficiencies 94.65% 98.31%, highlighting versatility for industrial household applications. flexible PCCO 10 also demonstrated excellent reusability (97.2% efficiency after four cycles) maintained structural integrity under low-frequency such centrifugation, vortexing, stirring, confirming activity degradation. Furthermore, products were identified LC-MS technique. Also, pot study established that these molecules have no phytotoxic effects neem (Azadirachta indica) plants. Hence, this multifunctional free-standing holds promising potential alternative sustainable treatment.
