Monolithic 1D nickel-based catalytic electrode with 2D graphene oxide for efficient hydrogen production by reconstruction of interfacial mass and charge transfer. |
| 초록 |
The study aims to develop monolithic, self-supporting catalyst electrode for efficient hydrogen production by water splitting. Monolithic nano-structure of catalyst electrode fulfills the facile mass and charge transfer which are pivotal for efficient hydrogen production by water splitting. Nickel-nanowires are prepared in the presence of the magnetic-field. Nickel-metals have ferromagnetic property, so these are arranged in a line by the magnetic-field. The mechanical and electrochemical properties are controlled by adjusting the strength of magnetic field and/or the amount of reductant. Graphene Oxide (GO) is homogeneously mixed with nickel nanowire to fabricate the freestanding Ni-GO monolithic electrode. It is observed that GO nanosheets are enveloped by 1D nickel matrix to promote the interfacial mass/charge transfer, leading to improvement in hydrogen evolution reaction (HER) activity. The role of GO can be further identified by the reduction of GO to reduced graphene oxide (rGO) |
