Carbon Coking‐Tolerant Perovskite Catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 for Efficient Methane Dry Reforming

Carbon and Hydrogen, EarlyView.
A new perovskite‐type catalyst Nd0.9Mg0.1Fe0.4Ni0.6O3 was developed for methane dry reforming, which exhibited 93.1% CH4 and 94.7% CO2 conversion with 100 h stability run and excellent anti‐coking capability, benefited from in situ exsolved Fe‐Ni alloy nanoparticles. ABSTRACT Perovskite with high temperature stability and tunability is a very promising

Small‐Crystal SAPO‐34 Preparation by Regulating Precursor Mixing Temperature for Methanol‐to‐Olefins Conversion

Carbon and Hydrogen, EarlyView.
By tuning the initial mixing temperature from 0°C to 80°C, the crystal size of SAPO‐34 can be adjusted from micro to nanoscale, reflecting a shift from classical single‐crystal growth at low temperatures to non‐classical polycrystalline aggregation at high temperatures.

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

Carbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis

Carbon Energy, EarlyView.
Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

Carbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Mechanistic Insights Into Sustainable Catalytic Pyrolysis of Biomass‐Derived Ferulic Acid: The Role of Alumina Regeneration

Chemistry – A European Journal, EarlyView.
Surface‐bound ferulate phenolate complexes undergo styrene‐like polymerization on alumina, yielding a polymeric carbonaceous layer that progressively transforms into polyaromatic carbon domains with concomitant release of aromatic products, while parallel surface‐assisted decarboxylation produces 4‐vinylguaiacol. ABSTRACT A fundamental understanding of

Using Displacement‐Assisted Desorption to Identify Reactive Intermediates: Ring‐Fused Porphyrins on Cu(111)

Chemistry – A European Journal, EarlyView.
We propose a novel displacement‐assisted approach for temperature‐programmed desorption (TPD), allowing for the detection of reactive intermediates of on‐surface reactions. We demonstrate the approach by investigating the temperature‐dependent ring fusion reactions (cyclodehydrogenations) of tetraphenylporphyrin on Cu(111), revealing the quantitative ...

Impact of Trace Water on the Macroscopic Activity of Commercial Ammonia Cracking Catalysts Under Process‐Relevant Conditions

Chemie Ingenieur Technik, EarlyView.
This study evaluates how small water impurities—typical in ammonia cracking feedstock—affect catalyst performance at elevated pressures and temperatures. By decoupling permanent degradation from reversible inhibition, the findings highlight trace water as a significant factor for reliable catalyst screening and industrial ammonia cracking scale‐up ...
