Abstract

Green synthesis of platinum nanoparticle using lemon peel extract is an alternative way to chemical synthesis of nanoparticles. This research was designed for the environmental friendly, pollution free, cost effective and has no side effects to the environment. The platinum nanoparticle was synthesized using (Citrus limon) lemon peel extract. Parameters such as time, pH, concentration, temperature and change in color from yellow to yellowish brown indicates the reduction of platinum ions which confirmed the synthesized platinum nanoparticle. The green synthesized platinum nanoparticle was further characterized by UV visible spectroscopy, Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction Spectroscopy (XRD). The results of the UV spectroscopy revealed the reduction of platinum ions to platinum nanoparticle at the peak of 344 nm. The results of the Scanning Electron Microscopy confirmed the morphology of platinum nanoparticle which were smooth and spherical with a diameter of range from 71 to 90 nm at 41.0 kx magnification. The results of the Fourier Transform Infrared Spectroscopy revealed the strong broad band between 1095 to 3244.00 cm-1 which confirmed the presence of functional groups. X- ray diffraction (XRD) analysis confirmed the crystalline structure of synthesized platinum nanoparticle with the distinct peaks at 39.0°, 46.3° and 67.5°. Therefore the green synthesized platinum nanoparticle is an advantage to the environment than the chemical approaches. This technique is efficient and holds potential for various industrial applications and is sustainable.
