Abstract The treatment of ammonia nitrogen wastewater (ANW) has garnered significant attention due to the ecology, and even biology is under increasing threat from over discharge ANW. Conventional ANW methods often encounter challenges such as complex processes, high costs secondary pollution. Considerable progress been made in employing solar-induced evaporators for treatment. However, there remain notable barriers transitioning fundamental research practical applications, including insufficient evaporation rates inadequate resistance biofouling. Herein, we propose a novel evaporator, which comprises bio-enzyme-treated wood aerogel that serves water pumping storage layer, cost-effective multi-walled carbon nanotubes coated hydrophobic/hydrophilic fibrous nonwoven mat functioning photothermal aggregation-induced emission (AIE) molecules incorporated anti-biofouling agent. resultant bioinspired evaporator demonstrates rate 12.83 kg m −2 h −1 when treating simulated containing 30 wt% NH 4 Cl 1.0 sun illumination. AIE-doped exhibits remarkable photodynamic antibacterial activity against mildew bacteria, ensuring outstanding biofouling extended periods When enhanced by natural wind irradiation, achieves an impressive exceeding 20 . This advancement represents promising viable approach effective removal wastewater.

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 18, 2025

Solar-powered interfacial evaporation has emerged as a promising, sustainable technology for clean water production with its minimal carbon footprint. Currently, extensive research efforts focus on enhancing solar rates and broadening the applicability of three-dimensional (3D) steam generators (SGs). For large-scale production, individual 3D SGs must be integrated into system-level SG arrays deployment in portable devices or distillation plants. Therefore, array's configuration plays an even more critical role boosting evaporation. From methodological perspective, development numerical simulation evaluation methods to predict is emerging frontier. Nonetheless, complex energy-water-solute interactions within remain largely underexplored. Herein, their are developed.
