Abstract A new type of lanthanum‐based high entropy perovskite oxide (HEPO) electrocatalyst for the oxygen evolution reaction is reported. The B‐site lattices in HEPO consist five consecutive first‐row transition metals, including Cr, Mn, Fe, Co, and Ni. Equimolar non‐equimolar electrocatalysts are studied their OER electrocatalytic performance. In HEPOs, concentration one metals doubled individual samples. performances all HEPOs outperform single oxides. optimized La(CrMnFeCo 2 Ni)O 3...
Layer-by-layer gold nanoparticles are used to generate photocurrent in an environmentally-friendly plasmon-sensitized solar cell towing surface plasmon resonance. The efficiency of the photoelectric conversion nanoparticle layers is increased as intensity resonance increases. We also explain experimental results by modeling phenomenon charge separation and formation, relationship between which has potential application cells plasmonic future. a can be improved depositing on cell’s surface....
Abstract Novel earth‐abundant metal sulfate‐containing high entropy sulfides, FeNiCoCrXS 2 (where X = Mn, Cu, Zn, or Al), are synthesized via a two‐step solvothermal method. It is shown that FeNiCoCrMnS exhibits superior oxygen evolution reaction (OER) activity with an exceptionally low overpotential of 199, 246, 285, and 308 mV at current densities 10, 100, 500, 1000 mA cm –2 , respectively, surpassing its unary‐, binary‐, ternary‐, quaternary‐metal counterparts. The electrocatalyst yields...

The effect of surface plasmon resonance (SPR) on the blinking emission photoluminescence from noble metal nanostructures still requires further investigation in quantum mechanics and limits their applications. We investigate one photon luminescent intermittency with differently sized sea-urchin-shaped nanoparticles, known as nano-sea-urchins (NSUs). probability "on" process NSUs increases due to strong electric field SPR. This mechanism is explained by reaction potential threshold model we...
