Separating Hydrogen Evolution From Electroplating in Zn Metal Batteries Using Scanning Electrochemical Microscopy

open access: yesAdvanced Energy Materials, EarlyView.
Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

Pt Single‐Atom Catalysts on FTO for Optically Invisible pH‐Universal Hydrogen Evolution Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
Comparison of the overpotential (η) at 10 mA cm−2 in acidic electrolyte of Pt SA on FTO (this work) and other literature. ABSTRACT Transparent hydrogen‐evolution electrodes are essential for photoelectrochemical and optoelectronic energy‐conversion devices, yet typically suffer from a trade‐off between catalytic activity and optical transmission. Here,

Water‐Mediated Proton Facilitation for Stable Acidic CO2 Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Proton‐mitigating Cu─O─Ce sites accelerate *CO formation and PCET‐mediated *CO─*CHO coupling, enabling efficient multicarbon production at relatively low current density. Maintaining a retentive acidic pH suppresses parasitic hydrogen evolution and preserves in situ CO2 availability for carbon‐efficient acidic CO2 reduction.

Interfacial Electronic Modulation of Vacancy‐Stabilized Pt Sites in Mo‐NiSeO4/NiSe2 Heterostructures for Industrial Alkaline Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
A vacancy‐stabilized Pt,Mo‐NiSeO4/NiSe2@Co2P heterostructure with atomically dispersed Pt sites and Mo‐regulated electronic structure enables efficient bifunctional water splitting. Strong interfacial coupling and defect‐assisted Pt stabilization promote rapid charge transfer and optimized intermediate adsorption, delivering outstanding HER/OER ...

Programming Structural Disorder in MOFs for a Stable Bifunctional Water‐Splitting Electrocatalyst

open access: yesAdvanced Energy Materials, EarlyView.
Introducing structural disorder into a highly active metal–organic framework enhances its stability. This improvement arises from the mitigation of destructive reconstruction during activation, thereby maintaining structural integrity and enabling long‐term durability.
