Frequent oil spill accidents have led to the severe pollution of water resources. Various techniques have been well developed for cleanup of crude oils in ocean. However, relatively little attention has been directed to cleanup and collection of hazardous noxious substance (HNS) such as benzene, toluene, and xylene. These chemicals are carcinogens and inflammable. Surprisingly, natural evaporation method is extensively used for cleanup of HNS, which results in the secondary contamination of air. We propose self-floating porous bulk spheres for sunlight driven-cleanup and collection of HNS. |
