Surface Restructuring of Nickel Sulfide Generates Optimally Coordinated Active Sites for Oxygen Reduction Catalysis
Crystalline Ni3S2 oxygen reduction reaction (ORR) catalysts undergo oxidative surface reconstruction under catalytic conditions to generate an approximately 2 nm amorphous surface layer with NiS stoichiometry. DFT calculations establish a simple local coordination number based descriptor for ORR catalysis and suggest that Ni atoms surrounded by three S nearest neighbors display optimal activity...

Growth Surface Model with Non Active Sites
In this work we studied the effects of non active sites on the substrate of a growing surface. In our model a particle only sticks at the surface if the site where it falls is an active site. However, we allow the deposited particle to diffuse along the surface in accordance with some previously defined mechanism. Using Monte Carlo simulations, and some analytical results, we have investigated ...
متن کاملSurface Chemistry and Catalysis
Nowadays, heterogeneous catalysis plays a prominent role. The majority of industrial chemical processes, involving the manufacturing of commodity chemicals, pharmaceuticals, clean fuels, etc., as well as pollution abatement technologies, have a common catalytic origin. As catalysis proceeds at the surface, it is of paramount importance to gain insight into the fundamental understanding of local...
متن کاملSurface science and catalysis.
During the last 20 years, surface scientists have developed a variety of techniques that make it possible to study, on the molecular level, the structure, composition, and chemical bonding in the surface monolayer. Both single-crystal model catalysts and real catalyst systems that are active in important chemical processes have been investigated by a combination of ultrahigh-vacuum surface scie...
