Operando X‐Ray Micro‐Imaging Reveals Spatiotemporal Evolution of the Oxidation State of Nickel During Dry Methane Reforming

Angewandte Chemie, EarlyView.
Operando X‐ray micro‐imaging enables quantitative determination of spatially resolved nickel redox rates during the process of dry reforming of methane and its subsequent regeneration. The support composition governs the local nickel redox dynamics, thereby exhibiting different local nickel reduction and oxidation rates. The spatiotemporal Ni oxidation

Lattice Nitrogen Couples Cuδ+ Stabilization With Pathway Control for CO2‐to‐Methanol Electroreduction

Angewandte Chemie, EarlyView.
Lattice‐incorporated nitrogen regulates amorphous CuO by forming a resilient Cu─N/O coordination environment that suppresses excessive Cu reduction and preserves Cuδ+ sites under reducing conditions. The resulting catalyst enables selective CO2‐to‐methanol conversion, achieving a methanol Faradaic efficiency of 48% in an H‐type cell and a methanol ...

Modeling of High-Pressure Methane Adsorption on Wet Shales

, 2019
Water is present in most shale reservoirs and has a negative effect on methane adsorption. A modified Langmuir model was developed to model methane adsorption on wet shales. This model was validated against published adsorption data on wet shales.

Thermally Regulated Methanol Selectivity in Photo‐Thermo Methane Oxidation Through Interfacial Methyl Transfer

Advanced Science, EarlyView.
Photo‐thermo cascade catalysis enables highly selective methane‐to‐methanol conversion over Au‐ZnO, achieving a CH3OH production rate of ∼800 µmol h−1 with 86% selectivity. Thermal activation gates the transfer of methane‐derived methyl intermediates from ZnO to Au, thereby redirecting the reaction pathway toward methanol formation. ABSTRACT The direct
