Journal ArticleDOI
Nanometre-scale spectroscopic visualization of catalytic sites during a hydrogenation reaction on a Pd/Au bimetallic catalyst
Hao Yin,Hao Yin,Li-Qing Zheng,Wei Fang,Yin-Hung Lai,Nikolaus Porenta,Guillaume Goubert,Hua Zhang,Hai-Sheng Su,Bin Ren,Jeremy O. Richardson,Jian-Feng Li,Renato Zenobi +12 more
TL;DR: In this article, the authors used tip-enhanced Raman spectroscopy (TERS) to study the catalytic hydrogenation of chloronitrobenzenethiol on a well-defined Pd(submonolayer)/Au(111) bimetallic catalyst, where the surface topography and chemical fingerprint information were simultaneously mapped with nanoscale resolution.
Journal ArticleDOI
Reversible catalysis for the reaction between methyl orange and NaBH4 by silver nanoparticles
TL;DR: Reversible catalysis for the reaction between MO and NaBH4 by Ag NPs was discovered for the first time.
Journal ArticleDOI
Nanoscale chemical imaging of reversible photoisomerization of an azobenzene-thiol self-assembled monolayer by tip-enhanced Raman spectroscopy
TL;DR: Interestingly, the cis isomers of azobenzene-thiol molecules were preferentially observed at Au grain edges, which is confirmed by density functional theory, and tip-enhanced Raman images after ultraviolet and blue light irradiation are shown with nanoscale spatial resolution, demonstrating a reversible conformational change.
Journal ArticleDOI
Solution Phase and Surface Photoisomerization of a Hydrazone Switch with a Long Thermal Half-Life.
Li-Qing Zheng,Sirun Yang,Jinggang Lan,Luzia Gyr,Guillaume Goubert,Hai Qian,Hai Qian,Ivan Aprahamian,Renato Zenobi +8 more
TL;DR: In insight into the hydrazone's switching mechanism on metal surfaces, it is found that C6 HAT switches on Au and Cu surfaces when irradiated with 415 nm, however it cannot isomerize on Ag surfaces, unless higher energy light is used.
Journal ArticleDOI
Rapid visual detection of quaternary ammonium surfactants using citrate-capped silver nanoparticles (Ag NPs) based on hydrophobic effect.
TL;DR: A rapid, sensitive and low-cost colorimetric method for detection of quaternary ammonium surfactants using citrate-capped silver nanoparticles (Ag NPs) was developed and was successfully utilized to the disinfectant residual sample.
