Novel self-supported reduced graphene oxide foam-based CoAu electrode: An original anode catalyst for electrooxidation of borohydride in borohydride fuel cell

Control of hydrogen release during borohydride electrooxidation with porous carbon materials

“…During the capture, electrooxidation of entrapped hydrogen occurs, which improved the use of sodium borohydride. 118 4.1.5 Heteroatom-doped carbons. Conductive polymers (electroactive conjugated polymers) are gaining attention due to the possibility of using them as catalytic supports in fuel cell electrodes.…”

“… 114 Several other advanced graphene-based nanomaterials such as Pd/rGO-Fe 3 O 4 , 115 AuNCage/G, 116 PdM (M = Fe, Ag, Au)/rGO 117 were also investigated to solve the challenges of DBFC. In a recent work, Li et al 118 created a new self-supporting CoAu electrode based on a reduced graphene oxide (rGO). The authors used the chronoamperometry technique to evaluate the electrocatalytic activity of their materials ( Fig.…”

A new catalyst for urea oxidation: NiCo2S4 nanowires modified 3D carbon sponge

“…For comparison, electrodes with different concentration ratios of Ni and Co (Ni:Co = 0:3, 1:2, 2:1, 3:0) in the hydrothermal process were also prepared. The preparation method of the cathode catalyst (Pd/Ti plate electrode) used in the fuel cell can be founded in our previous work [32] .…”

“…H 2 O 2 is employed as an efficient and superior oxidant in the DUHPFC [63 , 64] . Fuel cell structure adopted in this work is the same as our previously reported work [32] . Nafion 117 membrane is used as a cation exchange membrane.…”
