Cetyltrimethylammonium Bromide (CTAB) Bloated Micelles and Merged CTAB/Bolaamphiphiles Self-Assembled Vesicles toward the Generation of Highly Porous Alumina as Efficacious Inorganic Adsorbents

“…Inorganic porous materials with surprising traits such as large surface area and voluminous pores hold great promise for a new generation of adsorbents. − Nanoporous alumina (NPA) as a subset of porous materials has been used as an adsorbent due to its peculiar physiochemical properties such as surface with rich hydroxyl groups and Lewis acid sites, ability to attach to various compounds with different functional groups on their surface, high surface-to-volume ratio, low toxicity, and ability to be regenerated. ,− Antibiotic molecules usually contain −COOH and −NH groups and −Cl or −F atom as another electrostatic point. They could physically or interactively adsorb onto the surface of alumina .…”

“…Up to now, various methods have been utilized to synthesize porous materials such as template-free approaches and soft and/or hard templating method. , The syntheses based on a soft templating manner mostly rely on evaporation-induced self-assembly (EISA) . In this approach, interaction between surfactant micelles and guest species is crucial to form the mesoporous materials .…”
