This study reports on the preparation and characterization of porous clay heterostructure (PCH) as a high-surface area support for CuO nanoparticles based antibacterial activity for Gram-positive and Gram-negative bacteria. CuO nanoparticles were incorporated in PCH by thermal decomposition method and characterized by diffuse reflectance spectroscopy (DRS). X-ray diffraction (XRD).
