Nanomaterials such as [nano-adsorbents]() and [nanocatalysts]() can be used to remove pollutants from water. Nano-adsorbents, like carbon nanotubes and graphene oxide, have large surface areas and high reactivity, making them effective at trapping contaminants. Nanocatalysts can accelerate the breakdown of harmful substances into less toxic forms, often through processes like [photocatalysis]().
