Abstract:
... RhCo alloy nanotubes were synthesized via the reduction of single-phase Co₂RhO₄ nanotubes. The reduction was conducted by thermal annealing of the Co₂RhO₄ nanotubes under hydrogen gas flow. The crystallinity of the prepared RhCo alloy nanotubes depended on the reduction temperature: amorphous phase (200 °C reduction) and the crystalline phase (300 °C reduction). The hydrogen evolution reaction (HE ...
