Extraction of hydrogen from hydrocarbons is a logical intermediate-term solution for the escalating worldwide demand for hydrogen. This work explores the possibility of using a single membrane to accomplish both the catalytic dehydrogenation and physical separation of hydrogen gas as a possible way to improve the efficiency of hydrogen production from hydrocarbon sources. The present analysis shows that regions of pressure/temperature space exist for which the overall process is thermodynamically spontaneous (ΔG < 0). Each step in the process is based on known physics. The rate of hydrogen production is likely to be controlled by the barrier to hydrogen abstraction, with the density of H-binding sites also playing a role. A critical materials issue will be the strength of the oxide/metal interface.

“…Development of efficient and low cost hydrogen production technologies is an urgent task due to the increased demand of clean energy generation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. At present more than 50 million tons of hydrogen are produced annually worldwide and much of this hydrogen is used in the chemical and refinery industries [15].…”

“…At present more than 50 million tons of hydrogen are produced annually worldwide and much of this hydrogen is used in the chemical and refinery industries [15]. In the future, it is expected that H 2 could be widely used for power generation and in transport by fueling gas turbines, fuel cells and combustion engines [1][2][3][4][5][6][7][8][9][10][11]. The H 2 consumption rate steadily growths in the world and the 30% increase of global H 2 production is predicted in the next 5 years [15].…”

“…There are different technologies of hydrogen production using nonrenewable (natural gas reforming, coal gasification) as well as renewable (biomass processes, biological production etc.) resources, nuclear energy (high-temperature water splitting) and electricity (electrolysis of water) [3][4][5][6][7][8][9]. Although the "green" or carbon-neutral path from current fossil-based to future hydrogen economy is preferable and provides sustainable development [1][2][3][4], to date H 2 is usually produced from fossil fuels without CO 2 capture and storage [16,10,13].…”

Natural gas remains main feedstock for hydrogen production [8,13,14,16,17]. The typical technologies for production of hydrogen from natural gas are steam methane reforming (SMR), partial oxidation (POX) and autothermal reforming (ATR).…”

POSS (polyhedral oligomeric silsesquioxanes) nanotechnology was applied for preparation of efficient Ni catalysts for hydrogen production through autothermal reforming of methane (ATR of CH 4 ). The novel metal-POSS precursor [Nickel (II) -HeptaisobutylPOSS (C 4 H 9 ) 7 Si 7 O 9 (OH)O 2 Ni] of Ni nanoparticles was introduced into Ce 0.5 Zr 0.5 O 2 support with following calcination and reduction stages of activation. The peculiarity of the genesis of Ni/SiO 2 /Ce 0.5 Zr 0.5 O 2 nanomaterials and their characteristics versus deposition mode were studied by X-ray fluorescence spectroscopy, thermal analysis, N 2 adsorption, X-ray diffraction, high-resolution transmission electron microscopy and H 2 temperature-programmed reduction. The two kinds of supported Ni-containing particles were observed: highly dispersed Ni forms (1-2 nm) and large Ni-containing particles (up to 50-100 nm in size). It was demonstrated that the textural, structural, red-ox and, consequently, catalytic properties of ex-Ni-POSS catalysts depend on the deposition mode. The increase of a portion of difficultly reduced Ni 2+ species is found upon application of intermediate calcination during Ni-POSS deposition that has detrimental effect on the activity of catalyst in ATR of CH 4 . The Ni/SiO 2 /Ce 0.5 Zr 0.5 O 2 catalyst prepared by one-step Ni-POSS deposition exhibits the highest H 2 yield -80% at T = 800 °C.

Sustainable and cost-effective energy generation has become crucial for fulfilling present energy requirements. For this purpose, development of cheap, scalable, efficient, and reliable catalysts is essential. Carbon based heteroatom doped, three dimensional and mesoporous electrodes are very promising as catalysts for electrochemical energy conversion and storage. Various carbon allotropes doped with variety of heteroatoms can be utilized for cost-effective mass production of electrode materials. 3D porous carbon electrodes provide multiple advantages, such as, large surface area, maximized exposure to active sites, 3D conductive pathways for efficient electron transport, and porous channels to facilitate electrolyte diffusion. However, it is challenging to synthesize and functionalize isotropic 3D carbon WILEY-VCH This article is protected by copyright. All rights reserved. 2 structures. Here, various synthesis processes of 3D porous carbon materials are summarized to understand how their physical and chemical properties together with heteroatom doping dictate the electrochemical catalytic performance. Prospects of attractive 3D carbon structural materials for energy conversion, and efficient integrated energy systems are also discussed.This article is protected by copyright.

Other major printing techniques, such as inkjet printing, screen printing, and transfer printing, have also been commonly used for depositing nanostructured carbons onto substrates of varying size, surface energy, and flexibility for energy applications, though 3D printing is an emerging technology. [134][135][136][137][138][139][140][141][142][143][144] 3D printing can offer porous carbon structures of 10 m thick or thicker with very quick drying time (few sec). [133][134][135][136][137] Carbon allotropic nanomaterials combined with various polymers have been used as highly viscous inks for fabricating 3D printed carbon structures for Li-ion batteries, supercapacitors, water splitting electrolyzers, fuel cells, and environmental protection applications. [136][137][138][139][140] Figure 4 illustrates various electrodes fabricated by different 3D printing methods.
