“…Several researchers have published experimental work on H 2 storage by spillover mechanism. [299][300][301][302] Divya and Ramaprabhu [295] synthesized hydrogen-exfoliated graphene sheets decorated with the Pt nanoparticles (Pt-HEG) resulting in higher H 2 uptake of 1.4 wt% at 298 K/ 3 MPa than pristine HEG (0.5 wt%). This significant enhancement in H 2 storage capacity was attributed to the presence of Pt NPs which governed hydrogen spillover mechanism.…”

Moreover, burning fossil fuels intensifies the emission of greenhouse gases causing catastrophic climatic change. [1] Therefore, an alternative renewable energy with no greenhouse gases emission is highly needed. In this framework, hydrogen (H 2 ) is considered as a promising candidate for carbon-free energy production. [2] Additionally, H 2 is inexhaustibly abundant in nature and endowed with the intriguing features such as the lightest weight in the periodic table and generates high chemical energy of 142 MJ kg −1 per unit mass; about three times greater than the energy produced (47 MJ kg −1 ) by burning hydrocarbons. [3,4] Therefore, continuous efforts are being devoted to replace the conventional liquid hydrocarbon-driven socioeconomic system to hydrogen economy, which embraces the generation of H 2 , its storage, and ultimately energy transfer. [5] However, finding the efficient and economical means of H 2 storage is still a major challenge to be addressed before the practical implication of hydrogen economy. Generally, H 2 can be stored by different strategies including liquefaction method, [6] compression in gas cylinders, [7] adsorption on solid-state materials, [8] solid form as chemical hydrides, [9] and using metastable alloys which can absorb/desorb H 2 with faster kinetics at low temperature. [10] For the onboard applications, H 2 storage capacities should fulfill the goals set by the

“…57 It is improper to define the step adsorption as H chemisorption on Pt only, since the dispersion D of H chemisorption from step adsorption to total catalyst amount (M T ) ratios will be >100% when spillover occurs. Thus, we previously proposed the concept of pseudodispersion (μ  H/M T , step adsorption to total Pt ratio) and spillover efficiency (η  μ/D, the ratio between pseudodispersion to real Pt dispersion from the real Pt NP size from FE-TEM and also the ratio of spiltover H to atoms adsorbed on the Pt surface) 18,21 to estimate the hydrogen uptake improvement by spillover. If hydrogen spillover does not initiate, H chemisorption to total Pt (μ) should be ≤100, while the dispersion (μ) should be equal to dispersion (D) from FE-TEM.…”

“…To enhance hydrogen storage at ambient temperature, hydrogen spillover, a catalytic phenomenon of H 2 chemisorption and dissociation by catalyst nanoparticles (NPs) like the platinum group metal (PGM) followed by H surface diffusion to the supports, has been proposed . It has been reported to improve room-temperature hydrogen adsorption capacity in carbonaceous materials, MOFs, − and others. However, discrepancies in the literature draw disputes in hydrogen spillover .…”

In order to improve room-temperature hydrogen storage, platinum (Pt) nanoparticles (NPs) are doped onto the Zrterephthalate metal−organic framework (MOF) UiO-66 and its derivatives for H 2 adsorption via spillover effect under a highpressure environment. Different MOF synthetic modulators are applied for MOF nanoparticle size manipulation, and surface functionality is designed to improve Pt dispersion. Powder X-ray diffraction shows retained MOF integrity after Pt decoration, and the broad Pt peak indicates well-dispersed Pt NPs. The MOF high specific surface areas are slightly reduced after Pt doping with the retained micropore size in the nanometer scale. The hydrogen storage capacity can be improved from 0.08 to 0.71 wt % at 300 K and 30 bar. It is suggested by X-ray photoelectron spectroscopy that the hydrogen capacity enhancement is due to H 2 spillover in which spiltover hydrogen radicals hydrogenate carboxylates in MOF supports. Although Pt aggregation reduces H 2 capacity in cycles, it is found that MOF and Pt nanoparticle sizes are critical for H 2 spillover for subsequent room-temperature hydrogen storage.

The energetic and climate crises should pose a challenge for scientists in finding solutions in the field of renewable, green energy sources. Throughout more than two decades, the search for new opportunities in the energy industry made it possible to observe the potential use of hydrogen as an energy source. One of the greatest challenges faced by scientists for the sake of its use as an energy source is designing safe, usable, reliable, and effective forms of hydrogen storage. Moreover, the manner in which hydrogen is to be stored is closely dependent on the potential use of this source of green energy. In stationary use, the aim is to achieve high volumetric density of the container. However, from the point of view of mobile applications, an extremely important aspect is the storage of hydrogen, using lightweight tanks of relatively high density. That is why, a focus of scientists has been put on the use of carbon-based materials and graphene as a perspective solution in the field of H2 storage. This review focuses on the comparison of different methods for hydrogen storage, mainly based on the carbon-based materials and focuses on efficiently using graphene and its different forms to serve a purpose in the future H2-based economy.
