Value‐Added Aqueous Metal‐Redox Bicatalyst Batteries

Advanced Energy Materials, Год журнала: 2023, Номер 14(2)

Опубликована: Ноя. 27, 2023

Abstract The development and utilization of electrochemical energy conversion storage devices can maximize intermittent renewable balance environmental issues. Aqueous metal‐redox bicatalyst batteries, incorporating value‐added electro‐reduction reactions during discharge process at the cathode, are considered a particularly attractive alternative for simultaneous electricity generation valuable chemical production. In this review, first time, holistic subtle description batteries is made, focusing on recent efforts to optimize conversion/chemical production‐involved cathodic discharging reactions, including CO 2 reduction reaction (CO RR), nitrogen (NRR), nitric oxide (NORR), nitrate (NO 3 − nitrite hydrogen evolution (HER), acetylene (ARR). A macroscopic understanding design principles in terms anodes, cathodes, parameters provided. Some mechanism explorations, feasibility analyses, technoeconomic assessments, device combinations, associated comparisons involved deepen different systems evaluate their application prospects. Perspectives opportunities future research directions also outlined.

The intermediate toxic species COads produced by electrocatalytic oxidation of methanol have a high adsorption energy on the surface Pt active sites and are difficult to convert, which is main reason for poisoning deactivation electrocatalysts in direct fuel cells. In this study, series PtSn/CeO2-CNTs alloy catalysts were prepared an ethylene glycol hydrothermal reduction method using CeO2-modified carbon nanotubes (CNTs) as support. electrochemical properties PtSn measured reaction (MOR) probe reaction. results show that excellent performance mainly attributed introduction CeO2 synergistic effect among Sn intermetallic nanoparticles. An situ transient analysis platform investigated path molecules at interface Pt100-CNTs Pt42Sn58/CeO2-CNTs catalysts. It was clear converted CO path, synergistically promoted rapid conversion COads, effectively improved activity stability accelerated MOR rate. provides new idea basis rational design optimization electrocatalysts.
