Synthesis of Palladium Nanoparticles Supported over Fused Graphene-like Material for Hydrogen Evolution Reaction

The search for a clean abundant energy source brought hydrogen gas into the limelight; however, explosive nature of brings up issues with its storage. A way to mitigate this danger is through storing in feedstock material, which contains large percentage weight as hydrogen. Sodium borohydride material that gained lot attention it readily reacts water release This study explored novel composite composed palladium nanoparticles supported on sugar-derived fused graphene-like support (PdFGLM) ability catalyze reaction sodium water. Transmission electron microscopy (TEM), scanning (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FTIR), and diffraction (XRD) were used characterize determine size shape catalyst study. XRD detected presence nanoparticles, EDS date confirmed 3% nanoparticles. TEM result shows 5.5 nm incorporated layers. contained approximately palladium. In hydrogenation reactions, was observed optimal conditions included lower pHs, increased temperatures, dosages borohydride. had greatest generation rate 0.0392 mL min−1 mgcat−1 at pH 6. tested multiple times succession discovered increase volume produced, later trials indicating becomes more activated uses. activation catalyzed by PdFGLM found be 45.1 kJ mol−1, comparable other catalysts reaction. indicates has potential sustainable
