“…Outstanding surface areas nearly reaching 5000 m 2 g − 1 and high pore volumes confer considerable potential to MOFs as prospective materials for hydrogen storage. 16,17 A wide range of varying topologies and pore sizes from combinations of organic ligands and metal connectors has been explored. For example, highly porous cubic frameworks comprised of Zn 4 O(CO 2 ) 6 units coordinated by an octahedral array of 1,4-benzenedicarboxylate and benzene tribenzoate groups adsorbed 1 wt% hydrogen at room temperature (2 MPa) and 4.5-7.5 wt% at 78 K (0.08 MPa).…”

Safe and efficient hydrogen-carrying and -storing materials are in high demand for future hydrogen-based energy systems. Series of hydrogen carriers have been studied and examined, such as organic hydrides, metal hydrides and metal-organic frameworks; however, these carriers often suffer from safety issues and usually fix and store hydrogen at energy-consuming high pressures and/or temperatures. Here, we review organic polymers and their molecular design for hydrogen storage. Porous organic polymers, hypercrosslinked polymers and polymers with intrinsic microporosity reversibly stored and released hydrogen through hydrogen physisorption on their highly porous structures. Ketone and N-heterocycle polymers fixed and stored hydrogen at atmospheric pressure through the formation of chemical bonds to form the corresponding alcohol and hydrogenated N-heterocycle polymers, respectively. Electrochemical hydrogenation using water as a hydrogen source was also effective, in which the polymer worked as a scaffold for hydrogenation. The hydrogenated polymers released hydrogen in the presence of catalysts at mild conditions. The potential of using organic polymers in the quest for finding new types of hydrogen-carrying and -storing materials that are very safe and portable is suggested.

“…Furthermore it is a nontoxic liquid at room temperature with a density of 1.22 g/cm 3 , and can produce a gravimetric and volumetric H 2 capacities of 4.4 wt.% and 52 g/dm 3 , respectively. 30 Some noble metal-based catalysts (Ag, Pt and Pd) are the most selective towards H 2 production instead of CO and water formation (the undesired possible reaction). [31][32][33] Among them, Pd is one of the metals with the lowest activation energy and most promising TOF values.…”

Evolution of the PVP–Pd Surface Interaction in Nanoparticles through the Case Study of Formic Acid Decomposition

et al. 2016

Palladium nanoparticles (Pd NPs) were synthesised by the reduction-by-solvent method using polyvinylpirrolidone (PVP) as capping agent. The non-static interaction between PVP and the metallic surface may change the properties of the NPs due to the different possible interactions, either through the O or N atoms of the PVP. In order to analyse these effects and their repercussion in their catalytic performance, Pd NPs with various PVP/Pd molar ratios (1, 10 and 20) were prepared, deposited on silica and tested in the formic acid decomposition reaction. The catalytic tests were conducted using catalysts prepared by loading NPs with three different time lapses between their purification and their deposition on the silica support (1 day, 1 month, and 6 months). CO adsorption, FTIR spectroscopy, XPS and TEM characterisation were used to determine the accessibility of the Pd NPs surface sites, electronic state of Pd and the average NPs size, respectively. The H 2 production from the formic acid decomposition reaction has a strong dependence with the Pd surface features, which in turn are related to the NPs aging time due to the progressive removal of the PVP.
