A fluidized-bed model for NiMgW-catalyzed CO2 methanation

, 2020
The reduction of carbon dioxide to methane by hydrogen (“CO2 methanation”) using renewable energy is a promising process for recycling CO2. Better catalysts and better reactors are both required for the practical application of CO2 methanation.

High‐Current‐Density Acidic CO2 Electroreduction to Formic Acid Enabled by Multiscale Microenvironment Regulation Over Defect‐Rich Sn/SnOx

Advanced Science, EarlyView.
Acidic CO2 electroreduction to formic acid is enabled by integrating mixed Sn/SnOx nanoclusters, K+‐regulated interfacial solvation, and Janus wettability. Coordinated control of active sites, interfacial water, and gas‐liquid transport suppresses hydrogen evolution and delivers approximately 85% HCOOH Faradaic efficiency at 400 mA cm−2.

Scalable Fabrication of MOF Glass Membranes for Gas Separation via Stepwise Phase Transition

Advanced Science, EarlyView.
Metal‐organic framework (MOF) glass membranes, with their excellent processability and permanent pore structure, have great potential for gas separation applications. However, during large‐scale fabrication, defects and obvious cracks are prone to occur due to the limitations of powder processing.

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
