Delimiting the boron influence on the adsorptive properties of water and •OH radicals on H-terminated Boron Doped Diamond catalysts: A Density Functional Theory analysis
Raciel Jaimes, Jorge Vazquez-Arenas ⁎,1, Ignacio González, Marcelo Galván
Motivated for the success of Boron Doped Diamond (BDD) in electrocatalysis, where water and hydroxyl radical interactions play an overriding role on surface reactivity, this study presents a Density Functional Theory (DFT) analysis intended to correlate its structure and reactivity. H-terminated periodic surf...
Sensing polarization effects through the analysis of the effective C6 dispersion coefficients in NaCl solutions
Alfredo Guevara-García, Joel Ireta y Marcelo Galván
Density functional theory based ab initio molecular dynamics is used to obtain microscopic details of the interactions in sodium chloride solutions. By following the changes in the atomic C6 coefficients under the Tkatchenko-Scheffler's scheme, we were able to identify two different coordination situation...
DFT study of adsorption of the corrosion inhibitor 2-mercaptoiidazole onto Fe(100) surface.
Juan Radilla, Guillermo E. Negrón-Silva, Manuel Palomar-Pardavé, Mario Romero-Romo y Marcelo Galván
The adsorption of benzotriazole, an outstanding corrosion inhibitor, was characterized on Cu2O surfaces using density functional theory (DFT) calculations. Cu2O surfaces contain two distinct Cu sites: coordinatively saturated (CSA) and coordinatively unsaturated (CUS). The following surfaces were considered: ...
Experimental and Theoretical Analysis Accounting for Differences of Pyrite and Chalcopyrite Oxidative Behaviors for ProspectiveEnvironmental and Bioleaching Applications
René H. Lara, Jorge Vazquez-Arenas, Guadalupe Ramos-Sanchez, Marcelo Galvan, and Luis Lartundo-Rojas
The oxidative processes of pyrite (FeS2) and chalcopyrite (CuFeS2) of interest for bioleaching and/or bioremediation applications are evaluated in growing medium conditions to account for differences in their reactions mechanisms proposed with chemical and electrochemical analysis, and their electronic struct...
