Fe/FeC particles encapsulated in hollow carbon nanoboxes for high performance zinc-air batteries.

Zinc-air batteries are recognized for their environmental friendliness and high energy density; however, the slow kinetics of the oxygen reduction reaction (ORR) at the air electrode hinder their commercial viability. The research focuses on synthesizing cubic hollow carbon structures derived from Metal-Organic Frameworks (MOFs), which enhance catalytic performance through improved conductivity and mass transfer. The resulting Fe/FeC/HCNB catalyst demonstrates a half-wave potential of 0.

Density Functional Theory Study of Optical and Electronic Properties of (TiO) Clusters for Application in Solar Cells.

A range of solution-processed organic and hybrid organic-inorganic solar cells, such as dye-sensitized and bulk heterojunction organic solar cells have been intensely developed recently. TiO is widely employed as electron transporting material in nanostructured TiO perovskite-sensitized solar cells and semiconductor in dye-sensitized solar cells. Understanding the optical and electronic mechanisms that govern charge separation, transport and recombination in these devices will enhance their current conversion efficiencies under illumination to sunlight.
