Radiation-Induced Asymmetric Grafting of Different Monomers into Base Films to Prepare Novel Bipolar Membranes

open access: yesMolecules, 2021
We prepared novel bipolar membranes (BPMs) consisting of cation and anion exchange layers (CEL and AEL) using radiation-induced asymmetric graft polymerization (RIAGP).

Current–Voltage Characteristics and Solvent Dissociation of Bipolar Membranes in Organic Solvents

open access: yesMembranes, 2022
In this work, the chronopotentiometric responses, pH changes, and current–voltage (I–V) characteristics of bipolar membrane (BPM)/LiCl–organic solvent systems were measured and compared with those of the BPM/LiCl–water system.

Improving the Stability, Selectivity, and Cell Voltage of a Bipolar Membrane Zero‐Gap Electrolyzer for Low‐Loss CO2 Reduction

open access: yesAdvanced Materials Interfaces, 2023
Electrolyzers for CO2 reduction containing bipolar membranes (BPM) are promising due to low loss of CO2 as carbonates and low product crossover, but improvements in product selectivity, stability, and cell voltage are required.

Asymmetric acidic/alkaline N2 electrofixation accelerated by high‐entropy metal–organic framework derivatives

open access: yesCarbon Energy, 2023
High‐entropy materials are composed of five or more metal elements with equimolar or near‐equimolar concentrations within one crystal structure, which offer remarkable structural properties for many applications.

Electro-catalytic membrane reactors and the development of bipolar membrane technology [PDF]

open access: yes, 2004
Membrane reactors are currently under extensive research and development. Hardly any concept, however, is realized yet in practice. Frequently, forgotten as membrane reactors are electro-catalytic membrane reactors where electrodes perform chemical ...
