Abstract

The chemical synthesis of aniline based palladium materials was achieved by the use of the chemical oxidants, PdCl4 2- and PdCl62-. Complex formation was favored by using aniline and polymer formation was favored by the use of n-phenyl-1,4-phenylenediamine (NPPD). All materials were prepared with or without acid. Also, Characterization techniques such as FTIR spectroscopy, UV-Vis spectroscopy, Scanning Electron Microscopy, Thermogravimetric Analysis and X-ray Photoelectron Spectroscopy were used; Hydrogen sorption studies were carried out using a GC/Hydrogen Generator. The aniline complexes had sorption properties up to 1.5% and the NPPD composites showed sorption up to 0.7%. It was found that the materials produced with PdCl42- had higher sorption properties compared to the materials produced with PdCl62-; A separate study was performed using Sodium Borohydride to reduce palladium ions to metallic Pd in order to increase the rate and capacity of hydrogen sorption. Preliminary data showed the OM HCIO4 Pd2+ complex to have 1.8% sorption compared to 1.5% before reduction.
