“…Another ring-closure method that involves a radical mechanism is flash vacuum pyrolysis (FVP), which is normally conducted under high temperatures [88,89]. FVP is extremely useful in preparing bowl-shaped (geodesic) PAHs and fullerenes.…”

Polycyclic aromatic hydrocarbons in the graphene era

Polycyclic aromatic hydrocarbons (PAHs) have been the subject of interdisciplinary research in the fields of chemistry, physics, materials science, and biology. Notably, PAHs have drawn increasing attention since the discovery of graphene, which has been regarded as the "wonder" material in the 21st century. Different from semimetallic graphene, nanoscale graphenes, such as graphene nanoribbons and graphene quantum dots, exhibit finite band gaps owing to the quantum confinement, making them attractive semiconductors for next-generation electronic applications. Researches based on PAHs and graphenes have expanded rapidly over the past decade, thereby posing a challenge in conducting a comprehensive review. This study aims to interconnect the fields of PAHs and graphenes, which have mainly been discussed separately. In particular, by selecting representative examples, we explain how these two domains can stimulate each other. We hope that this integrated approach can offer new opportunities and further promote synergistic developments in these fields.

“…Finally, in vacuum pyrolysis reactors the feedstock is pyrolyzed under vacuum conditions (3.5-10 kPa) and do not require a carrier gas. The heating rate and the residence time are slow; therefore, the solid yield is high [500,501]. Figure 17.…”

Green Synthetic Fuels: Renewable Routes for the Conversion of Non-Fossil Feedstocks into Gaseous Fuels and Their End Uses

et al. 2020

Innovative renewable routes are potentially able to sustain the transition to a decarbonized energy economy. Green synthetic fuels, including hydrogen and natural gas, are considered viable alternatives to fossil fuels. Indeed, they play a fundamental role in those sectors that are difficult to electrify (e.g., road mobility or high-heat industrial processes), are capable of mitigating problems related to flexibility and instantaneous balance of the electric grid, are suitable for large-size and long-term storage and can be transported through the gas network. This article is an overview of the overall supply chain, including production, transport, storage and end uses. Available fuel conversion technologies use renewable energy for the catalytic conversion of non-fossil feedstocks into hydrogen and syngas. We will show how relevant technologies involve thermochemical, electrochemical and photochemical processes. The syngas quality can be improved by catalytic CO and CO2 methanation reactions for the generation of synthetic natural gas. Finally, the produced gaseous fuels could follow several pathways for transport and lead to different final uses. Therefore, storage alternatives and gas interchangeability requirements for the safe injection of green fuels in the natural gas network and fuel cells are outlined. Nevertheless, the effects of gas quality on combustion emissions and safety are considered.

“…In my research group in Brisbane we have used the analogous benzene-and pyridine-diazo oxides in syntheses of (aza)fulven-6-ones (Scheme 3). [32] We have investigated numerous aryl-and heteroaryldiazo compounds and the rearrangements of the carbenes formed from them [28,33] by flash vacuum pyrolysis (FVP) [34] or photolysis. [28,35] Thus, FVP of the sodium salts of benzaldehyde and tropone tosylhydrazones produced heptafulvalene arising from the dimerization of cycloheptatetraene (CHT) (Scheme 4).…”

This essay details the author’s work with high-energy molecules based on sulfur or nitrogen, or both, which started with amateur rocket propellants like zinc dust and sulfur followed by experiments with the highly sensitive compounds nitrogen trichloride and fulminating gold. Research on the inorganic and organic fulminates and the isomeric cyanates led to detailed investigations of reactive intermediates generated by flash vacuum pyrolysis or photolysis, in particular nitrenes and carbenes derived from azides, diazo compounds, triazoles, and tetrazoles and characterized in low temperature matrices.
