Supported ruthenium nanoparticles for supercritical water gasification - synthesis, activity and stability

Christopher Marc Hunston

Supercritical water gasification (SCWG) is a promising and versatile technology for the conversion of a variety of wet biomass streams into renewable natural gas. In this work, the focus was set on methane production with the help of an active and stable m ...

Temporary pause in the growth of atmospheric ethane and propane in 2015–2018

Hélène Paule Angot, Ilann Ernest Valentin Bourgeois

Atmospheric non-methane hydrocarbons (NMHCs) play an important role in the formation of secondary organic aerosols and ozone. After a multidecadal global decline in atmospheric mole fractions of ethane and propane – the most abundant atmospheric NMHCs – pr ...

Cu/Metal Oxide Hybrid Nanocrystals as Electrocatalysts for the CO2 Reduction Reaction

Seyedehbehnaz Varandili

The electrochemical CO2 reduction reaction (CO2RR) is envisioned to play a significant role in achieving carbon neutrality while contributing to storing renewable energies. Cu-based materials are among the most promising electrocatalysts. However, 16 diffe ...

Dissociative Sticking Probability of Methane on Pt(110)-(2×1)

Rainer Beck, Ana Gutiérrez González

In this work, we revisit the dissociative sticking of methane on Pt(110)-(2×1) using quasi-classical trajectory (QCT) calculations and supersonic molecular beam (SMB) experiments. Experimentally, we apply the King and Wells method and the reflection absorp ...

Copper-Catalyzed Cyanoalkylative Aziridination of N-Sulfonyl Allylamines

Jieping Zhu, Qian Wang, Minh Tu Ha, Weisi Guo

Reaction of N-arylsulfonyl allylamines with alkyl nitriles in the presence of di-tert-butyl peroxide (DTBP) and a catalytic amount of copper salt afforded homologated aziridines in 43-86% yield. A sequence involving addition of the in situ generated cyanom ...

Direct conversion of plastic materials into methane and liquid fuels

Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden, Wei-Tse Lee

The invention relates to a method for direct conversion of plastic materials into methane and/or liquid fuel and use of ruthenium-modified zeolite to catalyse this conversion. ...

Microbial-induced carbonate precipitation applicability with the methane hydrate-bearing layer microbe

Alexandra Clarà Saracho

Production of methane gas from the methane-hydrate-bearing layer below the deep-ocean floor is expected to be crucial in the future of energy resources worldwide. During the methane gas-production phase from the methane hydrate with the depressurisation me ...

State-to-state methane-surface scattering as a probe of catalytic activity

Rainer Beck, Maarten Eduard van Reijzen, Jörn Werdecker, Bo-Jung Chen

Quantum state-resolved scattering experiments for methane molecules colliding with a catalytically active nickel surface are compared to scattering from a nickel surface passivated by a single layer of graphene. The vibrational state distribution of the sc ...

Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability

Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, Alexandre Bagnoud

Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date. Here, we measured the kinetics of MOX in stream sediments of 14 sites to res ...

Platinum Nanoparticles on Sintered Metal Fibers Are Efficient Structured Catalysts in Partial Methane Oxidation into Synthesis Gas

Lioubov Kiwi

Efficient structured catalysts of partial methane oxidation into synthesis gas were obtained by electrochemical modification of the surface of sintered FeCrAl alloy fibers in an ionic liquid BMIM-NTf, with further introduction of platinum nanoparticles. It ...

Life cycle assessment integration into energy system models: An application for Power-to-Methane in the EU

François Maréchal, Victor Codina Gironès

As the EU energy system transitions to low carbon, the technology choices should consider a broader set of criteria. The use of Life Cycle Assessment (LCA) prevents burden shift across life cycle stages or impact categories, while the use of Energy System ...
