Electrodeposition of palladium on carbon nanotubes modified nickel foam as an efficient electrocatalyst towards hydrogen peroxide reduction

Rational Design of Novel Efficient Palladium Electrode Embellished 3D Hierarchical Graphene/Polyimide Foam for Hydrogen Peroxide Electroreduction

“…Obviously, it could be found that no redox peaks can be observed from 3D RPF substrate curve, indicating that the 3D RPF substrate is steady in harsh acid solution. Compared with the 3D RPF CV curves, PRP electrode exhibited a representative feature of polycrystalline Pd, which was consistent with the previous report on the basis of a Pd electrode in harsh acid medium . After electrodeposition, it was evident that a reduction peak occurred on the curve of PRP at around 0.46 V. It could correspond to the effective reduction of surface oxide of deposited Pd on the PRP electrode, revealing that the metal Pd is indeed electrodeposited on the 3D RPF substrate.…”

It could correspond to the effective reduction of surface oxide of deposited Pd on the PRP electrode, revealing that the metal Pd is indeed electrodeposited on the 3D RPF substrate. Besides, the current of PRP electrode obviously increased due to the hydrogen adsorption and desorption process near −0.1 V as well as the redox reaction of Pd on the PRP electrode.…”

An Efficient Electrocatalyst by Electroless Cobalt–Nickel–Phosphorus Alloy Plating on Three-Dimensional Graphene for Hydrogen Evolution Reaction

“…34 The rGO existed as many layered structures, which provided a larger surface area for the highly dispersed catalysts. 35 Figure 4C shows an SEM image of the Co-Ni-P/rGO/NF catalyst, which demonstrates that the deposited Co-Ni-P particles were uniformly coated on the surface of rGO/NF. Ni-P and Co-P were similarly deposited on rGO/NF, as shown in Figures 4D and 4E.…”

A modified ‘skeleton/skin’ strategy for designing CoNiP nanosheets arrayed on graphene foam for on/off switching of NaBH4 hydrolysis

“…Ni/GF was synthesized by solution casting using the Ni foam scaffold as the template, 27 which provided a large specic surface area for a high active material loading. 33 The morphologies of NiF and Ni/GF were analyzed by SEM, as shown in † shows a 3D porous structure and rough surface, with a characteristic wrinkle morphology originating from graphene oxide. The reduced graphene oxide nanosheets were assembled on the Ni foam template, forming a 'skeleton/skin' structure analogous to that found in the human body, with NiF as the skeleton, and the reduce grapheme oxide coating as the skin.…”
