Over-coupled resonator for broadband surface enhanced infrared absorption (SEIRA)

open access: yesNature Communications, 2023
Detection of molecules is a key issue for many applications. Surface enhanced infrared absorption (SEIRA) uses arrays of resonant nanoantennas with good quality factors which can be used to locally enhance the illumination of molecules. The technique has

Bifurcation of *COOH Pathway Determines HCOOH Formation in CO2 Electroreduction on Bismuth

open access: yesAngewandte Chemie, EarlyView.
Driven by the mechanistic debate of Bi‐catalyzed CO2‐to‐HCOOH conversion, ambiguity remains regarding true reaction pathways. To resolve this, we combined constant‐potential AIMD simulations with spectroscopic evidence to analyze the competitive pathways.

Trace Sulfur‐Doping Boosts NiCo Heterostructured Catalyst for Selective Glycerol‐to‐Formic Acid Electroreforming

open access: yesAdvanced Functional Materials, EarlyView.
A sulfur‐doped Ni–Co heterostructured catalyst is rationally designed to regulate interfacial electronic and adsorption properties for selective glycerol electrooxidation. The synergistic Ni–Co active sites promote hydroxide activation and glycerol adsorption, enabling efficient formic acid production and durable hydrogen generation under continuous ...

Positive Electrochemical Potentials Induce Enhanced Chemoselectivity and Activity in the Thermocatalytic Hydrogenation of 3‐Nitrostyrene

open access: yesAngewandte Chemie, EarlyView.
Induced by positive electrochemical potentials, thermocatalytic hydrogenation (TCH) of 3‐nitrostyrene with H2 delivers one single product with six‐fold enhanced yield. The enhanced selectivity and activity originate from changes in the adsorption geometry of 3‐nitrostyrene and in the surface concentration of 3‐nitrostyrene and hydrogen via a concurrent
