Performance of supported Au–Co alloy as the anode catalyst of direct borohydride-hydrogen peroxide fuel cell

Carbon-supported Pt–Co nanoparticles as anode catalyst for direct borohydride-hydrogen peroxide fuel cell: Electrocatalysis and fuel cell performance

“…The single fuel cell test was performed using a battery testing system (BTS-51800, Neware Technology Co. Ltd., China) at 25 C which was reported in our previous work [5,6,32]. The schematic of DBHFC was shown in Fig.…”

“…To the author's knowledge, there is little information available in literature about carbon-supported PteCo nanoparticles as anode catalyst for DBFC. In our previous studies, AueCo/C as anode electrocatalyst for DBHFC have been well studied [32]. It has been found that the AueCo/C catalysts exhibit much higher catalytic activity and stability for the direct electrooxidation of BH À 4 than Au/C catalyst.…”

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

“…In our previous works, we have successfully prepared AueCo, AueNi and AueZn bimetallic catalysts with different ratios, and found that the catalysts gave the excellent electrochemical performance for DBFC [9,35e37]. Based on our previous works [35,36], in this study we will prepare AueM/C (M ¼ Fe, Co, Ni, Cu and Zn) electrocatalysts with the original input atomic ratio of 1:1, compare systemically their electrocatalytic activity and reactivity kinetics for BH 4 À oxidation.…”

Nanoporous gold anode catalyst for direct borohydride fuel cell

“…NPG can be formed by a chemical etching process called dealloying which involves selective metal dissolution. Forty has shown that depletion gilding of a lessnoble metal from Au alloys results in an open, continuous nanoporous structure composed of Au [16]. As the Ag atoms in an Ag x Au y alloy are dissolved in acid, remaining Au atoms gather together in clusters that create a rough surface causing Au to evolve into a porous material.…”
