Flow‐Through Hollow Fiber Gas Diffusion Electrodes with Morphology‐Controlled In Situ Galvanic Grown Silver Catalysts for Enhanced CO Selectivity in CO2 Electroreduction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
The flow‐through hollow fiber gas diffusion electrodes can continuously deliver CO2 to catalytic sites to suppress the hydrogen evolution reaction, while the abundant 2D silver nanosheet structure enhances *COOH intermediate adsorption, promoting the electrochemical conversion of CO2 to CO.

Fischer-Tropsch Synthesis of Hydrocarbons Using Iron-Mordenite Catalysts [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1991
Fischer-tropsch catalysts with high activity and selectivity for olefins were produced using mordenite type SiO2/Al2O3= 12, 20, 28, 62 zeolite supported iron carbonyl compounds and were characterized by X-ray powder diffraction. The adsorptionof volatile

What Is the Best Use of Biomass? A Harmonized LCA‐TEA Framework Quantifying Economic and Environmental Metrics for Bioenergy Pathways

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
A harmonized LCA and TEA framework evaluates 19 bioenergy pathways, quantifying carbon intensity (CI), minimum fuel selling price (MFSP), and marginal abatement cost (MAC). CCS reduces CI to net‐negative values and lowers MAC by up to 64%, with bioelectricity achieving the lowest MAC and liquid biofuels critical for hard‐to‐abate sectors.

Fischer-Tropsch Catalyst for Aviation Fuel Production [PDF]

open access: yes
As the oil supply declines, there is a greater need for cleaner alternative fuels. There will undoubtedly be a shift from crude oil to nonpetroleum sources as a feedstock for aviation (and other transportation) fuels.

The Relationship Between Catalyst and Solvent in Hydrogenation via Condensed Phase Heterogeneous Catalysis

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
Heterogeneous catalysis has historically been developed in the gas phase, however, we have found it pertinent to highlight solvent effects that must be accounted for in liquid environments. Condensed phase catalysis, like that in biomass, petroleum and the conversion of CO2, stands to benefit from the typically overlooked discussion regarding the ...

Nickel Nanoparticles Prepared via Colloidal Synthesis as CO2 Hydrogenation Catalysts on Various Support Materials

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
Small aromatic ligands are used to synthesize Ni particles between 1 and 4.4 nm. After deposition on various supports, an alkylating agent and subsequent reduction procedure are used to remove the ligands. On SiO2, the Ni particles remained small, but on Al2O3 they sintered severely.

Considerations on coal gasification [PDF]

open access: yes
Commercial processes for the gasification of coal with oxygen are discussed. The Koppers-Totzek process for the gasification of coal dust entrained in a stream of gasifying agents is described in particular detail.

Carbon deposition in the Bosch process with ruthenium and ruthenium-iron alloy catalysts [PDF]

open access: yes
The effectiveness of ruthenium and the alloys 50Ru50Fe and 33Ru67Fe as alternatives to iron, nickel, and cobalt catalysts in recovering oxygen from metabolic carbon dioxide was investigated.

From Surfaces to Interfaces: Ambient Pressure XPS and Beyond [PDF]

open access: yes, 2018
The rapidly increasing field of surfaces under ambient conditions of temperature, and pressure in gas and liquid environments, reflects the importance of understanding surface properties in conditions closer to practical situations. This has been enabled

Material processing with hydrogen and carbon monoxide on Mars [PDF]

open access: yes
Several novel proposals are examined for propellant production from carbon dioxide and monoxide and hydrogen. Potential uses were also examined of CO as a fuel or as a reducing agent in metal oxide processing as obtained or further reduced to carbon ...
