Abstract: In this article modeling of  of hydrogen on Pd (1 1 1) surface by ultra-accelerated quantum chemical  (UA-QCMD) was reported for the better understanding of the role of hydrogen vacancy for the dissociative adsorption of hydrogen. Here we have demonstrated and examined the isolated steps of hydrogen dissociative adsorption on Pd (1 1 1) surface. The direct observations of dissociative adsorption of hydrogen on Pd (1 1 1) surface (different vacancy models) were successfully simulated. From the analysis of the change of electronic structures and the dynamics of dissociative , we can conclude that divacancy sites are inactive for dissociative adsorption of hydrogen on Pd (1 1 1) surface. Our findings suggest that H2 dissociation on Pd (1 1 1) requires an ensemble of at least three hydrogen vacancies.

Abstract:

 plays an important role in catalysis, due to its ability to store and release oxygen depending on the condition present in the catalyst environment. To analyze the role of ceria in , it is necessary to know the details of the interaction of ceria surface with environmentally sensitive molecules. This study was conducted using ultra accelerated quantum chemical . Its purpose was to investigate the reduction process of the (1 1 1) and (1 1 0) surfaces of ceria with atomic hydrogen as well as water desorption mechanisms from the surfaces. This simulation demonstrated that when a high-energy colliding  are adsorbed on the ceria, it pulls up an O atom from the ceria surfaces and results in the formation of a H2O molecule. This is the first dynamics simulation related to such reduction processes based on .

Abstract:
Ultra accelerated quantum chemical  (UA-QCMD) was used to study the dynamics of the hydrogen spillover process on Pt/CeO2  for the first time. The direct observation of  of hydrogen on Pt/CeO2 catalyst surface as well as the diffusion of dissociative hydrogen from the Pt/CeO2 catalyst surface was simulated. The diffusion of the  in the gas phase explains the high reactivity observed in the hydrogen spillover process. , change of adsorption states and structural changes were investigated. It was observed that parallel adsorption of hydrogen facilitates the dissociative adsorption leading to hydrogen desorption. Impact with perpendicular adsorption of hydrogen causes the  on the surface, which decelerates the hydrogen spillover. The present study also indicates that the CeO2 support has strong interaction with Pt catalyst, which may cause an increase in Pt activity as well as enhancement of the  dispersions and hence increasing the rate of hydrogen spillover reaction.
