Article Abstract

A hydroquinone (HQ)/1,2-dihydroxybenzene-3,5-disulfonic acid (Tiron) binary catholyte system is developed for membraneless zinc hybrid flow batteries, leveraging sequential redox reactions with complementary potentials to enhance energy density and electrochemical kinetics. The HQ-Tiron system achieves an energy density of 21.4 W h L and a peak power density of 102.3 mW cm.

Mn-Co Dual-Metal Single-Atom Catalytic Sites for Boosted Redox Kinetics in Aqueous Polysulfide/Ferricyanide Flow Batteries.

Nano Lett

July 2025

Key Laboratory of Automobile Materials (Jilin University), Ministry of Education, and School of Material Science and Engineering, Jilin University, Changchun 130022, China.

The sluggish redox kinetics of NaS/NaS and the uncontrollable crossover of polysulfides often result in limited reutilization of active materials, hindering the practical scalable application of polysulfide/ferricyanide flow batteries. By leveraging the bidirectional manipulation of redox kinetics of active species, diatomic Mn and Co sites anchored on nitrogen-doped carbon encapsulated graphite carbon felt was prepared. And a progressive "optimized d-band model" was revealed, in which the tunable d-band centers of Mn and Co were, respectively, regulated to enable facile electron extraction and injection during the NaS-NaS redox; then the synergistic catalytic effect renders the matrix with bidirectional acceleration.

Cu-In metallic hybrid is a promising non-noble catalyst for selective electrochemical CO reduction (eCOR) to CO, but the lack of direct assembly with a gas diffusion electrode (GDE) limits the further development of eCOR to CO with both high Faradaic efficiency (FE) and high current density. In this study, an in situ electrochemical spontaneous precipitation (ESP) method was applied for the first time to prepare GDE-combined Cu-In electrocatalysts. The optimum Cu-In catalyst consists of a nanoscale "core-shell" structure of polycrystalline CuO covered by the amorphous In(OH) interface.

Removal of binary Cr(VI) and Cd(II) from the catholyte of MFCs and determining their fate in EAB using fluorescence probes.

Bioelectrochemistry

Department of Civil and Environmental Engineering, The Pennsylvania State University, University Park, PA 16802, United States.

Electrochemically active bacteria (EAB) on the cathodes of microbial fuel cells (MFCs) can remove metals from the catholyte, but the fate of metals in the cells has not been examined in the presence of multiple metals. To study the relative uptake and fate of Cr(VI) and Cd(II) in cells, fluorescence probes were used to determine the amount and location of these metals in four different EAB on the biocathodes of MFCs. When both metals were present, less Cr(VI) was removed but Cd(II) uptake was not appreciably affected.

Electricity production from cellulose in a microbial fuel cell using a defined binary culture.

Environ Sci Technol

Microbial fuel cells (MFCs) convert biodegradable materials into electricity, potentially contributing to an array of renewable energy production strategies tailored for specific applications. Since there are no known microorganisms that can both metabolize cellulose and transfer electrons to solid extracellular substrates, the conversion of cellulosic biomass to electricity requires a syntrophic microbial community that uses an insoluble electron donor (cellulose) and electron acceptor (anode). Electricity was generated from cellulose in an MFC using a defined coculture of the cellulolytic fermenter Clostridium cellulolyticum and the electrochemically active Geobacter sulfurreducens.
