Cobalt Oxide Nanomaterials and Rare-Earth Hydrogen Storage Alloys

This research community focuses on the synthesis and electrochemical application of cobalt oxide nanoparticles and layered double hydroxides, alongside the development of rare-earth-based metal hydride alloys for hydrogen storage and battery systems.

The work centers on the green synthesis of cobalt oxide (Co3O4) and nickel hydroxide nanoparticles, often using plant extracts, for use in photocatalytic degradation of pollutants, antibacterial applications, and electrochemical sensing. A parallel strand involves the structural engineering of layered double hydroxides and rare-earth magnesium-nickel alloys to optimize hydrogen absorption and release for metal-hydride batteries and supercapacitors. Recurring methods include microwave-assisted synthesis, X-ray photoelectron spectroscopy, and electrochemical characterization, with a strong emphasis on tuning material morphology and phase composition to enhance catalytic activity and energy storage capacity.

The community is most heavily concentrated in research tracked for Nickel, representing 1.0% of all Nickel research, and Cobalt, also at 1.0% of all Cobalt research. It also includes a significant portion of Hydrogen research, accounting for 0.3% of that element's tracked papers.

The community comprises 6,846 papers, published primarily in the International Journal of Hydrogen Energy, Journal of Alloys and Compounds, and Journal of Power Sources.

Recent work continues to explore the electrochemical properties of Ni-doped Co3O4 for supercapacitors and the mechanisms of capacity decay in rare-earth magnesium-nickel hydrogen storage alloys.
