“…[130] Zeynali et al synthesized GO membranes on alumina tubes and demonstrated that H 2 permeability, selectivity, high stability and membrane costs were lower than that of Pd membranes. [145] Finally, Liu et al simulated the gas diffusion via nanographene and showed that this material had a high H 2 selectivity to other gases, making it a promising candidate for H 2 separation. Specifically, they found that H 2 could penetrate nanographene membranes, exhibited a diffusion barrier of 0.65 eV, and that the H 2 selectivity to other gases such as N 2 , O 2 , NO, CO, H 2 O, and CO 2 was up to 1033, which was higher than that of other membranes such as based on PG and polymer membranes.…”

Hydrogen gas (H2) is a viable energy carrier that has the potential to replace the traditional fossil fuels and contribute to achieving zero net emissions, making it an attractive option for a hydrogen‐based society. However, current H2 purification technologies are often limited by high energy consumption, and as a result, there is a growing demand for alternative techniques that offer higher H2 purity and energy efficiency. Membrane separation has emerged as a promising approach for obtaining high‐purity H2 gas with low energy consumption. Nevertheless, despite years of development, commercial polymeric membranes have limited performance, prompting researchers to explore alternative materials. In this context, carbon‐based membranes, specifically graphene‐based nanomaterials, have gained significant attention as potential membrane materials due to their unique properties. In this review, we provide a comprehensive overview of carbon‐based membranes for H2 gas separation, fabrication of the membrane, and its characterization, including their advantages and limitations. We also explore the current technological challenges and suggest insights into future research directions, highlighting potential ways to improve graphene‐based membranes performance for H2 separations.

“…Meanwhile, NPG membranes are more cost-efficient than polymer membranes under the same separation conditions and purification requirements. Zeynali et al [89] prepared GO nanocomposite membranes on modified alumina tubes, indicating their good H 2 permeability, favorable H 2 /CO 2 and H 2 /N 2 selectivity, and stability, accompanied with lower costs than Pd membranes. In addition, Liu et al [90] simulated the reaction path of gas molecules through nano-graphene C216 and proved that H 2 could penetrate C216 membranes with a diffusion barrier of 0.65 eV.…”

Nowadays, we face a series of global challenges, including the growing depletion of fossil energy, environmental pollution, and global warming. The replacement of coal, petroleum, and natural gas by secondary energy resources is vital for sustainable development. Hydrogen (H2) energy is considered the ultimate energy in the 21st century because of its diverse sources, cleanliness, low carbon emission, flexibility, and high efficiency. H2 fuel cell vehicles are commonly the end-point application of H2 energy. Owing to their zero carbon emission, they are gradually replacing traditional vehicles powered by fossil fuel. As the H2 fuel cell vehicle industry rapidly develops, H2 fuel supply, especially H2 quality, attracts increasing attention. Compared with H2 for industrial use, the H2 purity requirements for fuel cells are not high. Still, the impurity content is strictly controlled since even a low amount of some impurities may irreversibly damage fuel cells’ performance and running life. This paper reviews different versions of current standards concerning H2 for fuel cell vehicles in China and abroad. Furthermore, we analyze the causes and developing trends for the changes in these standards in detail. On the other hand, according to characteristics of H2 for fuel cell vehicles, standard H2 purification technologies, such as pressure swing adsorption (PSA), membrane separation and metal hydride separation, were analyzed, and the latest research progress was reviewed.

“…As shown by the studies carried out at the Kurchatov Institute, microporous ceramic tubes made of aluminum oxide are a good substrate for the preparation of nanocomposite membranes with a nanocarbon selective layer [68][69][70]. The authors of [94] synthesized a new type of such membranes with a GO monolayer deposited from a solution. The membranes showed stability, high hydrogen permeability, and good H 2 /CO 2 selectivity (separation factor >57).…”

The review is devoted to current and promising areas of application of graphene and materials based on it for generating environmentally friendly hydrogen energy. Analysis of the results of theoretical and experimental studies of hydrogen accumulation in graphene materials confirms the possibility of creating on their basis systems for reversible hydrogen storage, which combine high capacity, stability, and the possibility of rapid hydrogen evolution under conditions acceptable for practical use. Recent advances in the development of chemically and heat-resistant graphene-based membrane materials make it possible to create new gas separation membranes that provide high permeability and selectivity and are promising for hydrogen purification in processes of its production from natural gas. The characteristics of polymer membranes that are currently used in industry for the most part can be significantly improved with small additions of graphene materials. The use of graphene-like materials as a support of nanoparticles or as functional additives in the composition of the electrocatalytic layer in polymer electrolyte membrane fuel cells makes it possible to improve their characteristics and to increase the activity and stability of the electrocatalyst in the reaction of oxygen evolution.
