Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

A Self‐Sustained System for Producing Green Hydrogen via Moisture Power

Carbon Energy, EarlyView.
A multifunctional PAM‐PSSA‐MgCl2 gel enables a self‐powered Moisture‐Electricity‐Water‐Hydrogen system that harvests atmospheric water, generates electricity via moisture‐driven processes, and directly electrolyzes the collected water for hydrogen production. The material delivers 1.87 V, 450 μA cm−2 (MEG), and 1.318 g g−1 (AWH) water uptake, achieving

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Central sp3‐C Substitution Directs Supramolecular Assembly and Molecular Properties of Tris‐HBC Nanographenes

Chemistry – A European Journal, EarlyView.
Central sp3‐C substitution (─H, ─OH, ─CH3, ─OCH3, and ─OC2H5) directs supramolecular packing in tris‐HBC (hexa‐peri‐hexabenzocoronene) nanographenes, yielding diverse layered and porous architectures via modulation of intermolecular interactions. Comprehensive Raman, NMR, photophysical, and electrochemical analyses, supported by DFT/TD‐DFT calculations,

Internal Carbon Cycles in the Steel Industry: Pathways for CO2 Management and Carbon Capture Utilization

Chemie Ingenieur Technik, EarlyView.
The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.
