The Effect of Size and Morphology on the Antibacterial Activity of Zn‐loaded LTL Nanozeolite

A simple and cost‐effective approach was used to synthesize different morphologies of Linde Type L (LTL) nanozeolite. The resulting products were characterized by techniques such as X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electronic microscopy, and Brunauer‐Emmett‐Teller measurements. The results showed that LTL nanozeolite was successfully synthesized, and different morphologies, including spherical‐like and disk‐shaped nanoparticles, were obtained. Then, the effect of size and morphology on the antibacterial activity of the obtained products was studied. Spherical‐like LTL nanoparticles showed higher antibacterial activity due to their larger pore volume and surface area and higher loading of biocidal zinc cations. LTL nanozeolites with spherical‐like and disk‐shaped morphologies were synthesized by exploiting the effect of the alumina source, and the effect of size and morphology on the antibacterial activity of Zn‐loaded LTL nanozeolites was studied. Spherical‐like LTL nanozeolite showed higher antibacterial activity due to its larger surface area resulting in higher loading of Zn ions as antibacterial agent.
