Nanoporous materials are substances that contain tiny pores or voids, typically at the nanoscale, which is one billionth of a meter. These materials can have a high surface area, making them useful for various applications, including gas storage, catalysis, and filtration. Their unique structure allows them to selectively absorb or separate different molecules. Common examples of nanoporous materials include zeolites, metal-organic frameworks (MOFs), and carbon-based materials. Researchers are exploring their potential in areas like environmental remediation and drug delivery, as their porous nature can enhance the efficiency of these processes.
