Heterogeneous catalysts, which often consist of metal nanoparticles loaded on supports
such as metal oxides, can undergo several types of restructuring under reaction and …

Chemical interactions which occur at a heterogeneous interface between a gas and
substrate are critical in many technological and natural processes. Ambient pressure X-ray …

At the nanoscale, elastic strain and crystal defects largely influence the properties and
functionalities of materials. The ability to predict the structural evolution of catalytic …

Herein, atomic layer deposition (ALD)-Al 2 O 3 films were applied as a medium to modulate
the electronic states of the supported Pt. Based on the sacrificial template of ZIF-67, the …

To improve reactivity and achieve a higher material efficiency, catalysts are often used in the
form of clusters with nanometer dimensions, down to single atoms. Since the corresponding …

Pt nanoparticles supported on carbon are an important technological catalyst. A
corresponding model catalyst was prepared by physical vapor deposition (PVD) of Pt on …

Carbon monoxide participates in many copper-catalyzed reactions, which makes CO-
induced structural changes of Cu catalysts key for important industrial processes. We have …

Pt/ZrO2 model catalysts were prepared by atomic layer deposition (ALD) and examined at
mbar pressure by operando sum frequency generation (SFG) spectroscopy and near …

We studied the adsorption of CO on Pd/Pt nanoparticles (NPs) with varying compositions
using polarization-dependent Fourier transform infrared reflection absorption spectroscopy …

Abstract Infrared (IR)-visible (Vis) sum frequency generation (SFG) is a second-order
nonlinear optical process which is forbidden in centrosymmetric bulk media or isotropic …
