Enhanced Hydrogen Evolution Activity of MoS2 Through Solid Solution Modification of Its Edge Sites With Ruthenium

Angewandte Chemie, EarlyView.
Modulating the edge sites of molybdenum disulfide significantly boosts hydrogen production. By depositing Ru to form an edge‐coordinated solid solution, we accelerate water dissociation and shift the hydrogen evolution reaction pathway to Volmer–Tafel.

Surface-Enhanced Raman Spectroscopy Based on a Silver-Film Semi-Coated Nanosphere Array

Sensors, 2019
In this paper, we present a convenient and economical method to fabricate a silver (Ag)-film semi-coated polystyrene (PS) nanosphere array substrate for surface-enhanced Raman spectroscopy (SERS). The SERS substrate was fabricated using the modified self-

WGM Single‐Molecule Validation of pH‐Dependent Molecular Energetics at Gold Nanointerfaces: Influence of Buffer Molecules on Glyphosate Ligand Binding

Advanced Science, EarlyView.
Single‐molecule optical sensing reveals how pH and buffer molecules regulate glyphosate interactions with gold nanorods. Combined experiments and theoretical calculations show that changes in molecular charge and competition from buffer species determine whether glyphosate binds transiently or persistently.

Insights into the Degradation Mechanism of Aqueous LiMn2O4–Cathode Interfaces by Computational Vibrational Spectroscopy

Angewandte Chemie, EarlyView.
LiMn2O4${\rm LiMn}_2{\rm O}_4$ is of high interest for sustainable energy storage and conversion. Its mixed‐valence Mn3+${\rm Mn}^{3+}$/Mn4+${\text{Mn}}^{4+}$ structure drives site‐specific behavior at aqueous interfaces, featuring proton‐generating Mn4+${\text{Mn}}^{4+}$ centers and electron‐rich Mn3+${\rm Mn}^{3+}$ sites that render the surrounding ...

Surface Enhanced Raman Spectroscopy(SERS) of TMPyP on Ag Nanoparticles.

Journal of University of Anbar for Pure Science, 2015
This work was aimed to study the role of interaction between silver nanoparticles, TMPyP and Graphen Oxide(GO) on surface enhanced Raman scattering (SERS) signals. Silver nanoparticles(AgNPs) prepared by chemical reduction of AgNO3. SERS substrates show remarkable difference in spectral features due to the different enhancement contributions from the ...

Coordinating Mesopore Geometry and Interfacial Water Dynamics for Iron‐Site Evolution in Nitrate Electroreduction

Angewandte Chemie, EarlyView.
Mesopore geometry programs the working‐state interface of Fe single sites during nitrate electroreduction. Hexagonal channels reorganize interfacial water and accompany the reversible evolution of isolated Fe─O4‐like sites toward Fe─O─Fe‐like motifs, promoting successive hydrogenation toward NH3 with a Faradaic efficiency of 99.1%.
