Agni-catalyzed anode for direct borohydride fuel cells

Response to “Commentary about the number of electrons really involved in the direct oxidation of borohydride catalyzed by Ag and Ag-alloys determined by Gyenge and co-authors” by Umit. B. Demirci

“…Taking such an approach, we found that n was almost 8 for Ag, but the kinetics were slow. This is in good agreement with the findings of Chatenet et al [6] who reported a near 8e À oxidation of sodium borohydride on a Ag surface and Feng et al [7] who reported a 47e À oxidation of BH À 4 on Ag-or AgNi-catalysed anodes. Sanli et al [8], on the other hand, found from their coulometric studies that the number of electrons transferred from borohydride oxidation on an Ag surface was about 6.…”

Comparison of electrocatalytic activity of carbon-supported Au–M (M = Fe, Co, Ni, Cu and Zn) bimetallic nanoparticles for direct borohydride fuel cells

“…3(A)), indicating that introducing Fe or Zn into the FCC structure of Au, the BH 4 À oxidation reaction mechanism has scarcely been changed. The anodic oxidation of BH 4 À on AueFe/C and AueZn/C is mainly the direct electrochemical process, which is similar as that on Au/C surface [5].…”

First principles study of bimetallic Ni13−nAgn nano-clusters (n = 0–13): Structural, mixing, electronic, and magnetic properties

“…[27][28][29][30] Enhanced catalytic performance of Ni-Ag bimetallic nano-systems has also been used for the reduction of nitroarenes and construction of highly efficient direct borohydride fuel cells. [31,32] Small Ni-Ag nanoalloys have also been predicted to exhibit high spin states and could be a promising candidate for single-molecule magnetism. [33] However, to the best of our knowledge and contrary to expectation, in-depth electronic structure calculations correlating structure and property for the entire composition range of this interesting binary nano system, is lacking.…”
