| Abstract Scope |
Design and control of surface porosity is important for applications that depend on solid-fluid interactions such as adsorption, catalysis, and sensing. Natural biological surfaces optimize this through structural and functional hierarchy, where a larger porous structural material is bonded to progressively smaller functional entities to provide high levels of solid-fluid interaction in compact space. Recent advances in nanotechnology and surface engineering techniques have enabled our team to fabricate these types of materials where nanocatalyst particles are anchored on carpet-like arrays of electrically and thermally conducting carbon nanotubes (CNT) covalently bonded to porous substrates. These robust and reusable hierarchical materials have demonstrated significantly higher catalytic degradation rates of several environmental contaminants including persistent halogenated compounds. They are also showing promise as ultra-sensitive electrodes for electrochemical detection of pollutants in water. By strategically combining nanotube morphology and chemistry with appropriate nanocatalyst selection, these materials can enable sustainable and eco-friendly clean water technologies. |
