Platinum (Pt) nanoparticles have been synthesized from a precursor solution of potassium tetrachloroplatinate (K2PtCl4) using\na matrix of bacterial cellulose (BC). The formation of Pt nanoparticles occurs at the surface and the inside of the BC membrane\nby reducing the precursor solution with a hydrogen gas reductant.The Pt nanoparticles obtained from the variations of precursor\nconcentration, between 3mMand 30 mM, and the formation of Pt nanoparticles have been studied using X-ray diffraction (XRD),\nscanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), and thermogravimetry analysis (TGA). Based on\nX-ray diffraction patterns, Pt particles have sizes between 6.3nm and 9.3 nm, and the Pt particle size increases with an increase in\nprecursor concentration. The morphology of the Pt nanoparticles was observed by SEM-EDS and the content of Pt particles inside\nthe membrane is higher than that on the surface of BC membranes. This analysis corresponds to the TGA analysis, but the TGA\nanalysis is more representative in how it describes the content of Pt particles in the BC membrane.
