摘要: Abstract The development of light weight and compact hydrogen storage materials is still prerequisite to fuel-cell technology be fully competitive. present experimental study reports the capability sulfonated poly-ether-ether-ketone (SPEEK)-hexagonal boron nitride (h-BN) (SPEEK-h-BN) nanocomposite membranes. membranes are prepared by considering various amount h-BN (0, 1, 3 5 wt. %) phase inversion technique. degree sulfonation PEEK (SPEEK) found 65% Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy. Hydrogen adsorption studies have been carried out using a Seiverts-like hydrogenation setup. characterized X-ray Diffractometer (XRD), Micro-Raman spectroscopy, Fourier Transform Infrared (FTIR) Scanning Electron Microscopy (SEM), Atomic Force (AFM), CHN-elemental analysis Thermo Gravimetric Analysis (TGA). It observed that SPEEK-5% membrane performs better than pure SPEEK membrane, has maximum capacity 2.98 wt. % at 150 °C adsorbed an average binding energy 0.38 eV. TGA shows dehydrogenation behavior hydrogenated SPEEK-h-BN it in temperature range 214–218 °C for membrane.
