Improved oxidation stability of carbon-coated Ni nanoparticles synthesized by one-step electrical wire explosion

Jun-Hyeok Lee et al.

Summary: This study demonstrates a rapid one-step route to prepare high-purity carbon-coated Ni nanoparticles and investigates their oxidation stability. The thermal oxidation of Ni@C nanoparticles is closely related to the burn-off of protective carbon shells, which effectively prevents the active core Ni nanoparticles from high temperature oxidation in air.

Tunable metal-organic framework nanoarrays on carbon cloth constructed by a rational self-sacrificing template for efficient and robust oxygen evolution reactions

Chong Lin et al.

Summary: Metal-organic frameworks (MOFs) are promising materials for oxygen evolution reactions (OER) due to their unique properties, but challenges such as low conductivity and organic-ligand-shielded metal centers can be addressed by designing MOF nanoarrays (MOF NAs) on self-supporting and conductive substrates. Modulating the morphology and electronic properties of MOF NAs through strategies like using self-sacrificing templates and adjusting ligand dosage can enhance their catalytic activity and stability, unlocking their potential for OER applications.
