ClearRecent 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.

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.

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.
