Strengthening H gas-liquid mass transfer using superaerophobic cathodes for enhanced methane production from CO in H-mediated microbial electrosynthesis system.

H-mediated microbial electrosynthesis (MES) could run under a high current density, but the low solubility of H limited its performance. Reducing the H bubble size facilitates H gas-liquid mass transfer and it has been reported to be realized on superaerophobic electrodes. Therefore, we adopted a CoP nanowire-modified nickel foam (CoP-NiF) as the superaerophobic cathode in a H-mediated MES reactor to enhance the methane production from CO.

Iron carbide nanoparticles supported on an N-doped carbon porous framework as a bifunctional material for electrocatalytic oxygen reduction and supercapacitors.

Highly active and durable bifunctional materials are of pivotal importance for energy conversion and storage devices, yet a comprehensive understanding of their geometric and electronic influence on electrochemical activity is urgently needed. Fe-N-C materials with physical and chemical structural merits are considered as one of the promising candidates for efficient oxygen reduction reaction electrocatalysts and supercapacitor electrodes. Herein, FeC nanoparticles supported on a porous N-doped carbon framework (denoted as FeC/PNCF) were readily prepared by one-step chemical vapor deposition under the assistance of a NaCl salt template.

Electrochemical deposition of flower-like nanostructured silver particles with a PVA modified carbon cloth cathode.

A novel electrochemical method for preparing flower-like nanostructured silver particles using polyvinyl alcohol (PVA) modified carbon cloth as a cathode is reported. The method does not involve the use of any morphological control agents in aqueous solution. The morphology of the silver nanoparticles obtained was studied using scanning electron microscopy (SEM) and X-ray diffractometry (XRD).
