The adsorption and desorption kinetics of molecules is of significant fundamental and applied interest. In this paper, we present a new method to quantify the energy barriers for the adsorption and desorption of gas molecules on few-atom clusters, by exploiting reaction induced changes of the doping level of a graphene substrate. The method is illu...
Pt/CeO2 has gained much attention for their high activity in low-temperature (LT) water-gas shift (WGS) reaction. However, the inclusion of H2 in the feed as in the practical reaction condition significantly degrades the LT-WGS activity of the Pt/CeO2 catalysts. In this contribution, the activity of Pt/CeO2 catalyst under the feed gas containing ex...
Electrocatalysis is important to the conversion and storage of renewable energy resources, including fuel cells, water electrolysers, and batteries. Engineering metal-based nano-architectures and their atomic-scale surfaces is a promising approach for designing electrocatalysts. Single metal atom interactions with substrates and reaction environmen...
CeO2-based nanostructures have recently aroused interest for various applications because of their higher OSC and redox properties, allowing them to facilely switch between the oxidation states of Ce4+ and Ce3+. There are many studies that have been focused on the morphology-dependent catalysis and identification of the true active sites during cat...

The recently discovered carbon allotrope GDY possesses rich acetylenic bonds and unique pore structures, prompting GDY as an ideal candidate, tuning its electronic structure by introducing heteroatoms, broadening its usage in catalysis, energy storage and other fields. In this paper, we review different approaches to introduce heteroatoms into GDYs...

The local activation overpotential describes the electrostatic potential shift away from equilibrium at an electrode/electrolyte interface. This electrostatic potential is not entirely satisfactory for describing the reaction kinetics of a mixed ionic–electronic conducting (MIEC) solid-oxide cell (SOC) electrode where charge transfer occurs at the ...
Heterogeneous enantioselective catalysis is considered a promising strategy for the large-scale production of enantiopure chemicals. In this work, polymer-capped Pt nanocatalysts having a uniform size were synthesized using poly(vinyl pyrrolidone) (PVP) and poly(vinyl alcohol) and supported on gamma-Al2O3. After a facile heat treatment process, the...
