cu complex grafted on the porous materials: synthesis, characterization and comparison of their antibacterial activity with nano-cu/nay zeolite

In this work, the copper complex is introduced to porous materials, mcm-41 and nay zeolite, by two ways. in the first way, nano-copper was incorporated into nay zeolite (nay/nano-cu), and in the second way, alkylaminopyridine/cu complex grafted on mcm-41 and hy zeolite pores (z-hy@pr-py, z-hy@pr-py/cu). the prepared composites have been characterized by several techniques: scanning electron microscopy, energy-dispersive x-ray analysis chemical analysis, diffuse reflectance spectroscopy, fourier transform infrared spectroscopy, powder x-ray diffraction analysis and thermogravimetric analysis. the results have been shown that the cu complex and nano-copper ions were supported successfully on porous materials. the synthesized samples were investigated in vitro for antibacterial activity against gram-positive (b. subtilis and s. aureus) and gram-negative (e. coli and p. aeruginosa) bacteria and compared with standard drugs. the results show that introducing nano-copper or anchoring the cu complex to porous materials has affected the inhibition of bacterial growth. also, there is no significant releasing of copper ions from alkylaminopyridine/cu complex which was grafted on porous materials in comparison with nay/nano-cu until 24 h.
