Properties of Polymer Electrolyte Membranes Prepared by Blending Sulfonated Polystyrene with Lignosulfonate

Journal of Mathematical and Fundamental Sciences, 2014
A polymer electrolyte membrane widely used in PEMFCs and DMFCs is a perfluorosulfonated membrane (the Nafion membrane). This perfluorosulfonated membrane material exhibits good chemical stability and proton conductivity, but it is very expensive and ...

Constructing Enzyme‐Inspired Multisite Synergistic Catalyst for Promoting CO2 Electroreduction to Ethylene at pH Universal Condition

Carbon Energy, EarlyView.
A rational synthesis strategy was developed to construct enzyme‐inspired Cu‐AM catalysts with well‐defined multisite architectures. This catalytic system enables highly selective electrochemical CO2 reduction to C2H4 under pH‐universal conditions, delivering exceptional Faradaic efficiencies across acidic, neutral, and alkaline electrolytes.

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.

Coupling Atomic Confinement With CO2 Pressure for Selective and Stable CO2 Electroreduction

Carbon Energy, EarlyView.
The coupling of high‐pressure operation with atomic‐scale catalyst design was investigated via an electrochemical cation implantation (ECI) process to create confined reaction environments over SnOx catalyst. The synergistic interplay between structural confinement and CO2 pressure was investigated, and the reaction mechanism for CO2RR to CO was ...
