    Hydrogen sorption using a manganese oxide anchored to PEEK (Poly(ether-ether-keton)) matrix wasstudied. The functionalization process and the obtained results on hydrogen storage capability of thesynthesized polymer are reported. The functionalised polymer was characterised by Scanning ElectronMicroscopy, Transmission Electron Microscopy, X-ray diffraction and Volumetric Hydrogen sorptionmeasurements. Different synthesis conditions in terms of precursor concentration and reaction timewere used and the direct correlation between manganese oxide percentage and hydrogen storagecapability was confirmed. In this way different powders were synthesised. It is assumed that the samplewith 78 wt% (SPMnO6) forms a combination of mixed manganese oxides since different reticular planeswere observed. On this sample, promising results regarding to hydrogen capability at 110 C and 60 barwere obtained, in particular 1.1 wt% hydrogen sorption was recorded. Moreover, this value, after about30 h, remains quite constant. These preliminary results demonstrate the capability of such compound toabsorb hydrogen, for this reason further morphological and structural studies are in progress with theaim to better understand the mechanism involving the storage.
