Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

Advanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.

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

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

Advanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

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 ...

Properties of lignite and key factors determining the methane adsorption capacity of lignite: New insights into the effects of interlayer spacing on adsorption capacity

Fuel Processing Technology, 2019
Abstract The lignite reservoir and related parameters that determine the adsorption capacity remain largely unexplored and not understood. The coal composition, pore characteristics, mineral matter, coal rank, and molecular structure of lignite were systematically studied, and the influence of various factors on the adsorption capacity was analyzed ...
