AI Article Synopsis
- * The material achieves a power conversion efficiency of 8.42% in quasi-solid-state dye-sensitized solar cells and can efficiently split water, with a solar-to-hydrogen conversion efficiency of 5.58%.
- * Quaternary Fe Ni Co Se outperforms ternary nickel cobalt selenide in conductivity, electrocatalytic performance, and photovoltaic efficiency due to a beneficial synergistic effect.
Article Abstract
Iron nickel cobalt selenides are synthesized through a one-step hydrothermal method. Quaternary Fe Ni Co Se demonstrates multifunctionality and shows high electrocatalytic activity for quasi-solid-state dye-sensitized solar cells with a power conversion efficiency of 8.42 %, the hydrogen evolution reaction, the oxygen evolution reaction, and water splitting. The electric power output from tandem quasi-solid-state dye-sensitized solar cells under one-sun illumination is sufficient to split water and exhibits a solar-to-hydrogen conversion efficiency of 5.58 % with Fe Ni Co Se as the electrocatalyst in this integrated system. Owing to a remarkable synergistic effect, quaternary Fe Ni Co Se is proven to be superior to ternary nickel cobalt selenide in terms of conductivity, electrocatalytic activity, and photovoltaic performance.

Corrinoids are cobalt-containing tetrapyrroles. They include adenosylcobalamin (vitamin B) and cobamides that function as cofactors and coenzymes for methyl transfer, radical-dependent and redox reactions. Though cobamides are the most complex cofactors in nature, they are essential in the acetyl-CoA pathway, thought to be the most ancient CO-fixation pathway, where they perform a pterin-to-cobalt-to-nickel methyl transfer reaction catalyzed by the corrinoid iron-sulphur protein (CoFeS).

This study analyzed surface water from the River Swat, Pakistan, using inductively coupled plasma mass spectrometry, multivariate statistical techniques, and US-EPA risk assessment models to evaluate the concentrations, distribution, pathways, and potential risks of arsenic (As) and heavy metals, including chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), mercury (Hg), and lead (Pb). The results revealed significant correlations (p ≤ 0.01) among metals that indicated common pollution sources, likely influenced by anthropogenic point and non-point activities.
