Abstract The interfacial photothermal‐photocatalytic systems can generate clean water while purifying wastewater containing organic pollutants, but the impact of thermal convection on synergistic effects remains unexplored. This paper aims to regulate at interface significantly enhance effect systems. A novel heterogeneous structure comprising iron‐based metal‐organic frameworks and multi‐walled carbon nanotubes with a gelatin‐polyvinyl alcohol (PVA) double network hydrogel (MWCNTs@NM88B/PVA/gelatin hydrogel, denoted as MMH) is developed employed in construction solar‐driven evaporation (SIE) system. system shows high activity for solar simultaneous photocatalytic degradation pollutants. MMH demonstrates an rate 2.84 kg m −2 h −1 , achieving efficiency 95.3% under 1 sun. COMSOL simulations reveal that implementation three‐phase configuration SIE technology boosts convection, effectively diminishing barrier gas release from reaction consequently enhancing process. Furthermore, potential mechanism decomposition pollutants MMH/H 2 O /visible light proposed by combining experiments KPFM, situ XPS, ESR spectra. Therefore, this work offers fresh perspective evaluating pollutant
