Mixed‐Potential‐Driven Catalysis: An Electrochemical Mechanism for Room‐Temperature CO Oxidation on Gold Catalysts

open access: yesAdvanced Science, EarlyView.
Gold catalyzes low‐temperature CO oxidation, yet its mechanism is debated. A model system is designed to verify that it proceeds via a mixed‐potential‐driven reaction mechanism involving coupled electrochemical CO oxidation half‐reaction and O2 reduction half‐reaction.

A Tunable Strategy for Continuous Production of Electrolyte‐Free Formic Acid and Sodium Formate in a Solid‐State‐Electrolyte Based Electrocatalytic CO2 Reduction System

open access: yesAdvanced Science, EarlyView.
A tunable strategy based on Membrane electrode assembly‐SSE (MEA‐SSE) cells to continuously generate electrolyte‐free formic acid/sodium formate solution, holds high potential for industrial applications. Abstract Electrocatalytic CO2 reduction reaction (CO2RR) based on solid‐state‐electrolyte (SSE) reactors can efficiently convert CO2 to electrolyte ...

Ion‐Pair Interactions in Polyphenylene‐Based Quaternized Membranes Designed for Phosphoric Acid‐Doped Proton Exchange Membranes for High‐Temperature Fuel Cells

open access: yesAdvanced Science, EarlyView.
Quaternized polyphenylene‐based membranes with tailored hydrophobic groups (C7‐QAF and BAF‐QAF) exhibit high phosphoric acid uptake, acid retention, proton conductivity, and stability. Their well‐developed microphase‐separated structures and robust ion‐pair interactions enable superior fuel cell performance at 140 and 160 °C without humidification ...

Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.
