“…For instance, activated carbon from hardwood displays a higher activity than carbon black (black pearls 2000) despite their similar surface areas. The same tendency was detected with structurally close carbons with the same surface area, such as carbon black and acetylene black. ,, The higher activity of carbon black is attributed in this case to the larger amount of oxygenated surface groups. Different trends were observed when analyzing the activity of several coal chars and activated carbons .…”

“…This suggests that only a part of the surface area is involved in the decomposition of methane . In other studies, carbons with comparable surface areas show very different catalytic activities, which also indicates an apparent nonrelationship between the surface area and the activity. ,, This was observed when comparing carbons of a different nature. For instance, activated carbon from hardwood displays a higher activity than carbon black (black pearls 2000) despite their similar surface areas.…”

“…The initial activity has not only been related to the threshold temperature but also to the initial methane decomposition rate at constant temperature. Despite this difference in the measure of initial activity, there is general agreement that carbons with a greater number of surface defects are catalytically more active. ,,− ,,,− …”

“…Although the defect concentration of the carbon structure seems to be the most important parameter affecting the catalytic activity, other factors, such as the specific surface area and the concentration of oxygenated groups, can also influence the catalyst performance. For instance, carbons with higher surface areas usually exhibit superior catalytic activities than poor surface area materials. ,, An approximately linear relationship in logarithmic scale has been established between the initial activity of different carbon samples and their surface areas. In other cases, despite the greater catalytic activity of carbons with larger surface areas, the relationship between both parameters is not linear. ,− Hence, the surface area cannot be the only determining factor, and the number of defects also plays a crucial role.…”

Hydrogen plays a key role in many industrial applications and is currently seen as one of the most promising energy vectors. Many efforts are being made to produce hydrogen with zero CO2 footprint via water electrolysis powered by renewable energies. Nevertheless, the use of fossil fuels is essential in the short term. The conventional coal gasification and steam methane reforming processes for hydrogen production are undesirable due to the huge CO2 emissions. A cleaner technology based on natural gas that has received special attention in recent years is methane pyrolysis. The thermal decomposition of methane gives rise to hydrogen and solid carbon, and thus, the release of greenhouse gases is prevented. Therefore, methane pyrolysis is a CO2-free technology that can serve as a bridge from fossil fuels to renewable energies.

The insatiable—and ever-growing—demand of both the developed and the developing countries for power continues to be met largely by the carbonaceous fuels comprising coal, and the hydrocarbons natural gas and liquid petroleum. We review the properties of the chemical elements, overlaid with trends in the periodic table, which can help explain the historical—and present—dominance of hydrocarbons as fuels for power generation. However, the continued use of hydrocarbons as fuel/power sources to meet our economic and social needs is now recognized as a major driver of dangerous global environmental changes, including climate change, acid deposition, urban smog and the release of many toxic materials. This has resulted in an unprecedented interest in and focus on alternative, renewable or sustainable energy sources. A major area of interest to emerge is in hydrogen energy as a sustainable vector for our future energy needs. In that vision, the issue of hydrogen storage is now a key challenge in support of hydrogen-fuelled transportation using fuel cells. The chemistry of hydrogen is itself beautifully diverse through a variety of different types of chemical interactions and bonds forming compounds with most other elements in the periodic table. In terms of their hydrogen storage and production properties, we outline various relationships among hydride compounds and materials of the chemical elements to provide some qualitative and quantitative insights. These encompass thermodynamic and polarizing strength properties to provide such background information. We provide an overview of the fundamental nature of hydrides particularly in relation to the key operating parameters of hydrogen gravimetric storage density and the desorption/operating temperature at which the requisite amount of hydrogen is released for use in the fuel cell. While we await the global transition to a completely renewable and sustainable future, it is also necessary to seek CO 2 mitigation technologies applied to the use of fossil fuels. We review recent advances in the strategy of using hydrocarbon fossil fuels themselves as compounds for the high capacity storage and production of hydrogen without any CO 2 emissions. Based on these advances, the world may end up with a hydrogen economy completely different from the one it had expected to develop; remarkably, with ‘Green hydrogen' being derived directly from the hydrogen-stripping of fossil fuels. This article is part of the theme issue ‘Mendeleev and the periodic table'.
