Photocatalytic CO2 Reduction Over BiOX on Needle Coke–Derived Graphene Composites

Carbon and Hydrogen, EarlyView.
By in situ growing BiOX on needle coke–derived graphene to construct a composite photocatalyst, interfacial charge transfer is effectively enhanced. The optimized BiOBr‐25%NCG achieves a CO production rate of 46.32 μmol·g−1·h−1 from photocatalytic CO2 reduction without sacrificial agents.

Advances in Systems Engineering of Carbon Dioxide Electroreduction

Carbon and Hydrogen, EarlyView.
Industrializing CO2 electroreduction hinges on holistic systemic synergy and optimization of all process segments rather than isolated catalytic breakthroughs; Process simulation is a core enabler to build a complete capture–conversion–product industrial chain, positioning CO2RR as a key technology for carbon neutrality.

Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

Carbon and Hydrogen, EarlyView.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Ruthenium‐Based Catalysts Supported on Lanthanum and Carbon‐Modified Alumina for Low‐Pressure Ammonia Synthesis

Carbon and Hydrogen, EarlyView.
We proposed a new “hydrogen transfer–desorption” synergistic regulation strategy and developed a Ru/Al2O3‐La‐C catalyst with dual functions. La‐O sites were constructed and carbon components were introduced into the catalyst to regulate the two key steps of hydrogen transfer and desorption on the catalyst surface, respectively, solving the problem of ...

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

Carbon and Hydrogen, EarlyView.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...
