The evaluation of the flexibility in zeolitic imidazolate frameworks (ZIFs) has been very useful to understand their performance gas adsorption and separation applications. Here, we have evaluated properties a nanoporous mixed-linker ZIF-62 using combination measurements, grand canonical Monte Carlo simulations, synchrotron X-ray powder diffraction under operando conditions. While studies at 77...

The electroreduction of CO2, driven by renewable electricity, can be used to sustainably generate synthetic fuels. So far, only copper-based materials have been catalyse the formation multicarbon products, albeit limited C2 or C3 molecules. Herein, we disclose that inorganic nickel oxygenate-derived electrocatalysts linear and branched C6 hydrocarbons with sustained Faradaic efficiencies up 6.5...

The 8# coal seam in the Benxi Formation of southeastern margin Ordos Basin is a deep with abundant coalbed methane resources. Calcite veins are commonly developed within seam, and their formation processes mechanisms have significant implications for enrichment methane. Genesis calcite was analyzed to reveal impact on accumulation, an integrated application petrographic study by thin section, c...

In an investigation of gas hydrates in deep ocean sediments, gas samples from Deep Sea Drilling Project Site 533 on the Blake Outer Ridge in the northwest Atlantic were obtained for molecular and isotopic analyses. Gas samples were collected from the first successful deployment of a pressure core barrel (PCB) in a hydrate region. The pressure decline curves from two of the four PCB retrievals a...

The silver-catalyzed, oxidative coupling of methane to C2 hydrocarbons (OCM) is shown to be an extremely structure-sensitive reaction. Reaction-induced changes in the silver morphology lead to changes in the nature and extent of formation of various bulk and surface -terminating crystal structures. This, in-turn, impacts the adsorption properties and diffusivity of oxygen in silver which is nec...

Controlling the stoichiometry of supported bimetallic nanoparticles is essential in many catalytic reactions, notably selective CO2 hydrogenation. Thus, a new strategy to ensure preferred (1:1) PdZn presented, involving deposition heterobimetallic precursor, [PdZn(μ-OOCMe)4]2 on CeZrOx support. After calcination and reduction, material contained mainly alloy, as revealed by powder XRD XAFS, fur...

In the present work, decomposition of benzene as a tar model compound was studied in gas mixture (CO2, H2, CO, and CH4) using dielectric barrier discharge (DBD) non-thermal plasma reactor. The combined effect temperature power to investigate performance DBD increased from 49.9 96% with increasing specific input energy (SIE) 2.05 16.4 kWh/m3. major products were lower hydrocarbons (C2–C5) solid ...
