p-type Ce0.3Fe1.5Co2.5Sb12 skutterudite with the goal of increasing its thermoelectric power factor and figure of merit. Indium is soluble in polycrystalline Ce0.33InyFe1.5Co2.5Sb12 until y = 0.08 ± 0.03. Beyond this concentration, InSb nano-inclusions (∼40–200 nm in size) form at the grain boundaries during the shaping stage. Upon indium double-filling the skutterudite, the hole concentration is reduced
composed of earth-abundant elements for oxygenevolution have gained significant attention. In this study, a FeCo alloy electrocatalyst with an amorphous and porous structure was designed and prepared. The electrochemical test results showed that the amorphousalloy product with a Co:Fe molar ratio of 2:1 showed an optimal intrinsic catalytic activity for oxygenevolution. At a current density of 10 mA cm−2
