Nanocomposites of Tin Hydroxide Phthalocyanine Sn(OH)2Pc and Titanium Dioxide Nanoparticles for Improved Antimicrobial Activities
In this research, nanocomposite [TiO2-Sn(OH)2Pc] of titanium oxide (TiO2) and tin hydroxide phthalocyanine, Sn(OH)2Pc was prepared in the ratio of 1:4 respectively for improved antimicrobial activities. Cassava leaf extract (Manihot esculenta) was used as a bioreductant for the synthesis of TiO2NPs. The prepared TiO2 NPs was doped with Sn(OH)2Pc to investigate their, reaction, structure, morphology and antimicrobial activities on clinical microorganisms. The tin -phthalocyanine Sn(OH)2Pc, titanium dioxide nanoparticles (TiO2 NPs) and nanocomposite [TiO2-Sn(OH)2Pc] were characterized using the UV-Visible spectrophotometry, Fourier Transform Infrared Spectrophotometry (FTIR), Energy Dispersive Spectrometry (EDX), Powdered X-ray Diffractometry (PXRD), Scanning electron microscpopy (SEM) and Transmission Electron Microscopy (TEM). UV-Visible spectra revealed that Sn(OH)2Pc, TiO2 NPs and TiO2-Sn(OH)2Pc showed maximum absorption peaks at 632 nm, 344 nm and 500 nm respectively. FTIR results of Sn(OH)Pc, TiO2 NPs and TiO2-Sn(OH)2Pc showed prominent reactive functional groups for OH between 3300 and 3500 cm− 1 for all the materials among other characteristic groups. The EDX results revealed the elemental composition with percentages of the elements in the nanomaterials. The morphology of the synthesized materials were found irregular for [Sn(OH)2Pc] and TiO2NPs and spherical for TiO2-Sn(OH)2Pc. The particle size of the nanoparticles was found to be 15.4 nm, 80 nm and 60 nm for [Sn(OH)2Pc], TiO2NPs and TiO2-Sn(OH)2Pc respectively. Antimicrobial studies carried out on selcted Gram positive bacteria and Gram negative bacteria and fungi revealed good antimicrobial properties in all but with improved activities in the nanocomposite TiO2-Sn(OH)2Pc.
期刊介绍：
Journal of Inorganic and Organometallic Polymers and Materials [JIOP or JIOPM] is a comprehensive resource for reports on the latest theoretical and experimental research. This bimonthly journal encompasses a broad range of synthetic and natural substances which contain main group, transition, and inner transition elements. The publication includes fully peer-reviewed original papers and shorter communications, as well as topical review papers that address the synthesis, characterization, evaluation, and phenomena of inorganic and organometallic polymers, materials, and supramolecular systems.
