The development of high-performance membranes to address the issue vanadium ion crossover in redox flow batteries (VRFB) is a significant area focus. Current commercial perfluorinated suffer from economic impracticality, poor selectivity, and electrolyte leakage. In this report, we present composite membrane called PANI-Si@PP, which exhibits exceptional selectivity for protons over ions due Donnan exclusion by positively charged polyaniline backbone presence well-defined proton conductive...
Rational design of active and stable bifunctional electrocatalysts for the generation hydrogen oxygen is crucial clean renewable energy. Herein, we developed a robust method preparation from RuO 2 phosphomolybdic acid (PMA)-encapsulated multi-walled carbon nanotubes (MWCNT). It involves low-temperature thermal encapsulation PMA followed by anchoring at sites ion exchange. @PMA/MWCNTs showed an exceptionally low overpotential 41 mV evolution reaction (HER) with Tafel slope 71 d −1 ec in...
An economically viable thermally annealed cation exchange membrane for polysulfide-based redox flow batteries.
Herein we report about 75% acid recovery from bentonite mine effluents by diffusion dialysis (DD) using facile one-pot synthesized PVDF- co -HFP based anion exchange membrane. The trade-off between the hydrophilicity and hydrophobicity of membrane was maintained optimizing ratio 2,4,6 tris-(dimethylaminomethyl) phenol (TDP) to achieve desirable water content, ion selectivity, diffusivity. with highest TDP/PVDF- wt. i.e., M-5 had capacity uptake 1.05 meq/g 35.4% respectively, along good...
