Integrating photocatalytic processes into solar-driven interfacial evaporation technology is an effective approach to combat pollutants threat. However, the challenge lies in synergizing each component to achieve "Symbiotic Co-evolution", which is critical for achieving more with less. Our strategy for the fabrication of hydrogel evaporator (TA-Fe-SA/CoV₂O₆@Ti₃C₂Tx evaporator) was integrated by thermal vibration and local surface plasmon resonance (LSPR) effect, achieving efficient degradation and evaporation. On the one hand, the integration of thermal vibration and LSPR effect boosted the heat storage and local heating capacity of evaporator, while reducing equivalent enthalpy for enhancing evaporation. On the other hand, the synergistic effect of thermal vibration and LSPR triggered the efficient electron transfer of CoV₂O₆@Ti₃C₂Tx MXene Mott-Schottky heterojunction. As a result, it could achieve nearly 100 % bacteriostatic efficiency and 82 % ARGs removal within 1 hour. Additionally, the rapid generation of vapor and enhanced photothermal conversion strengthened thermal convection formation, accelerating gas release from the reaction system and improving the efficiency of the interfacial photothermal evaporation-photocatalytic process. These results highlighted the feasibility and scientific value of achieving synergy through the deliberate integration of photothermal materials and photothermal-catalysts into SIE technology, providing new perspectives for designing high-performance evaporators.
