Synergistic modulation of Ru oxidation state and oxygen vacancies in HfxRu1−xO2 for efficient acidic water electrolysis

Nano Research
Proton exchange membrane water electrolysis (PEMWE) is a key technology for sustainable hydrogen production; however, its efficiency is limited by the sluggish kinetics and high overpotential of the anodic oxygen evolution reaction (OER).

Tailoring Se‐Mediated Co‐Co Dual‐Atom Sites for Oxygen and Iodide Electrocatalysis Toward High‐Efficiency and Ultradurable Zinc‐Air/Iodide Hybrid Batteries

Carbon Energy, EarlyView.
A Se‐mediated Co dual‐atom catalyst replaces sluggish oxygen evolution with efficient iodide oxidation in zinc‐air/iodide hybrid batteries. Se‐induced d‐p orbital hybridization optimizes adsorption, enabling a low 0.365 V voltage gap and superior durability, fundamentally overcoming conventional kinetic bottlenecks.

A multiple-band perfect absorber for SEIRA applications

Sensors and Actuators B: Chemical, 2018
Abstract Recently perfect absorbers (PAs) have received significant interest due to their characteristics of complex electric permittivity (e) and magnetic permeability (μ). By rationally designing these artificial structures, the impedance of the perfect absorber can be matched to free space with an independent adjustment in the electric and ...

Pressure‐Enhanced CO2‐to‐CO Electroreduction on Ag‐Based Catalysts: Industrially Relevant Rates and Mechanistic Insights

Carbon Energy, EarlyView.
Ag‐based catalysts operated under elevated CO2 pressures exhibit markedly enhanced intrinsic activity for CO formation, with OD‐Ag achieving −200 mA cm–2 and 90% FECO at −1.3 VRHE. Mechanistic analysis shows that high pressure strengthens a *COOH‐mediated pathway by increasing intermediate coverage and suppressing hydrogen evolution, establishing CO2 ...
