Polymeric filtration membranes could be a cost-effective alternative to cation exchange (CEMs) in electrolysis with contained anolyte and saltwater catholyte because they size selectively hinder salt ion transport between compartments while facilitating proton hydroxide transport. Optimizing membrane performance requires better understanding of properties that impact electrical resistances rete...

Electrochemical CO2 reduction poses a promising pathway to produce hydrocarbon chemicals and fuels without relying on fossil fuels. Gas diffusion electrodes allow high selectivity for desired carbon products at current density by ensuring sufficient mass transfer rate the catalyst layer. In addition transfer, product also strongly depends local pH surface. this work, we directly visualize first...

The use of renewable energy sources for electricity generation is increasing, and effective storage solutions are needed to manage the mismatch between production demand. Redox Flow Batteries (RFBs), particularly Membrane-Free based on Aqueous Biphasic Systems (ABSs), a promising technology stationary storage. However, prevent crossover species, redox-active compounds used in catholyte anolyte ...

A novel microbial fuel cell-assisted electro-permanganate process (MFC-PM) was proposed for enhanced diclofenac degradation compared to that of the permanganate oxidation process. By utilizing eco-friendly bio-electricity in situ, MFC-PM could activate simultaneous anodic biological metabolism urea and cathodic Density functional analysis experimental evidence revealed reactive manganese specie...

BACKGROUND This work develops a simplified mathematical model to predict the performance of bioelectrochemical system (BES), first working as microbial fuel cell (MFC) and then electrolysis (MEC), for recovery dissolved metals (Fe, Cu, Sn, Ni) from simulated industrial wastewater. Experimental data previous were used starting points modelling. Wastewater was catholyte contained Cu2+ Fe3+ (500 m...

BACKGROUND Volatile fatty acids (VFA) are building blocks for the chemical industry. Sustainable, biological production is constrained by production and recovery costs, including the need for intensive pH correction. Membrane electrolysis has been developed as an in situ extraction technology tailored to the direct recovery of VFA from fermentation while stabilizing acidogenesis without caustic...

Here we reported the investigation of enhanced performance for the removal of hexavalent chromium (Cr (VI)) by a new microbial fuel cell (MFC) with natural pyrrhotite-coated cathode. By comparisons of the graphite-cathode, the MFCs equipped with a pyrrhotite-coated cathode generated the maximum power density of 45.4 mW·m−2 that was 1.3 times higher than that of with bare graphite cathode (35.5 ...

Energy storage is a vital aspect for the successful implementation of renewable energy resources on global scale. Herein, we investigated redox cycle nickel dithiocarbamates potential use as catholytes in non-aqueous flow batteries. The unique (Ni(dtc)2) offers ability to better understand these reactions by displaying 2e- chemistry upon oxidation from Ni(II) → Ni(IV) but 1e- reduction Ni(III) ...
