Calcination‐Induced Pore Evolution in TiO2 Supports Governing Ni Accessibility for Dry Methane Reforming

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
Ni/TiO2 catalysts with tunable pore structures were developed to study how support calcination temperature affects Ni accessibility and dry reforming of methane (DRM, CH4 + CO2 → syngas). Low‐temperature TiO2 forms mesopores that trap Ni, while high‐temperature calcination generates macroporous/plate‐like structures that expose Ni and enhance catalytic

Low‐Temperature Reverse Water–Gas Shift Enabled by Magnetically Induced Catalysis

open access: yesAngewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Magnetically induced catalysis using standard Cu–Al spinel‐derived catalyst functionalized with carbon‐coated iron nanoparticles enables high CO yield (up to 62%) at mild catalyst and reactor temperatures (estimated at 300°C and determined as 25–123°C, respectively).

Emerging Technologies for Biobutanol Production via Syngas Fermentation

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

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.
