Advances in photothermal water evaporation: synthesis, mechanisms, and coupled techniques
Summary
This review covers advances in materials that use sunlight to purify water through evaporation, which can produce clean water from seawater, rivers, and wastewater. While not specifically about microplastics, these solar-powered water purification technologies could potentially help remove microplastics from contaminated water sources. The development of more efficient and affordable systems could be important for providing clean drinking water in areas affected by microplastic pollution.
Recent advancements in light-driven interfacial water evaporation have underscored the potential of photothermal materials for producing clean water from various sources, including seawater, rivers, lakes, and wastewater. Despite these advancements, challenges in environmental management and energy conversion persist. The development of multifunctional photothermal materials and composites has addressed these challenges by integrating active species into water evaporation devices, thereby enhancing their performance and applicability. This review provides a thorough examination of recent progress in photothermal materials for water purification. It covers advances in material synthesis, optimization of evaporator configurations through various techniques, and their application in water treatment and clean water production.

Recent Progress on Solar‐Driven Interfacial Evaporation for Resource Recovery and Pollutant Removal
This review covers recent advances in solar-powered water purification systems that can recover resources and remove pollutants from water. While the technology is primarily designed for desalination and heavy metal removal, it has potential applications for filtering microplastics from water. These sustainable, energy-efficient systems could become an important tool for reducing microplastic contamination in drinking water supplies worldwide.
Microplastic detection and remediation through efficient interfacial solar evaporation for immaculate water production
Researchers developed a solar-powered water purification system that simultaneously produces clean water and removes microplastics, achieving up to 5.5 times better microplastic removal than previous methods. The system uses sunlight to evaporate water, leaving contaminants including microplastics behind. This dual-purpose technology could help address both water scarcity and microplastic pollution, ultimately reducing human exposure through drinking water.
Review on the Application of Novel Materials for Microplastics and Nanoplastics Removal in Drinking Water Treatment Systems
Researchers reviewed four categories of emerging materials — plant-derived adsorbents, advanced membranes, solar-powered photothermal systems, and electrochemical technologies — for removing microplastics and nanoplastics from drinking water. Each approach has trade-offs in cost, efficiency, and scalability, and the authors conclude that future solutions will likely require combining multiple technologies into hybrid systems.
Concave microlens arrays with tunable curvature for enhanced photodegradation of organic pollutants in water: A non‐contact approach
Researchers designed reusable concave microlens arrays (MLAs) that focus sunlight to boost solar photodegradation of organic pollutants in water by 5.1-fold, even under low light and in turbid river water. This is not directly about microplastics; it is a water treatment technology study targeting dissolved organic pollutants, making it a false positive for microplastic relevance.
Dual-Functional Evaporator: Synergistic Seawater Purification via Photothermal Evaporation and Microplastic Adsorption
A novel solar-powered device tackles two pressing problems at once: freshwater scarcity and microplastic contamination in water. The evaporator uses sunlight to generate steam for desalination while a specially coated fiber layer adsorbs microplastics from the water before it evaporates — achieving 99.2% microplastic removal efficiency and a strong evaporation rate. Because the steam produced contains no microplastics, the design elegantly separates clean water production from plastic capture in a single low-energy system.
