Rational construction of efficient and stable transition-metal (TM)-based electrocatalysts for oxygen evolution reaction (OER) is extraordinarily favored crucial to water/seawater splitting. Interface heteroatom engineering are powerful strategies improving the performance OER. Herein, we report a unique hydroxide/oxide heterostructure catalyst with P doping (Ni(OH)2/NiFe2O4–P) by an in situ growth strategy, following low-temperature phosphorylation boosting water oxidation. The...
Spinel-type oxides exhibit great potential for the electrocatalytic oxygen evolution reaction (OER) due to their variable surficial composition and electronic structure. Herein, taking MgCo2O4 as a prototype, we put forward surface engineering procedure tailor valence state of cobalt ions enhancing OER performance. We discovered that calcination temperature can finely ratio Co/Mg Co3+/Co2+ on MgCo2O4. with maximum gives current density 10 mA cm–2 at small overpotential 283 mV. Such an is...
Spinel oxides exhibit considerable potential as electrocatalysts for the oxygen evolution reaction (OER) owing to their diverse surficial composition and electronic structure. Engineering spin state of metal ions has been acknowledged an effective approach improving OER activity. However, comprehensively understanding intricate connection between structure activity still poses challenges. In this study, we present a temperature-induced lattice distortion strategy manipulate spinel ZnCo2O4,...
Chemical pressure generated through ion doping into crystal lattices has been proven to be conducive exploration of new matter, development novel functionalities, and realization unprecedented performances. However, studies are focusing on one-time doping, there is a lack both advanced investigations for multiple sophisticated strategies precisely quantitatively track the gradual functionality evolution along with progressive chemical implementation. Herein, high-valent Y3+ equal-valent Mg2+...
Doping chemistry has become one of the most effective means tuning materials' properties for diverse applications. In particular scheelite-type CaWO4, high-oxidation-state doping is extremely important, since may expand scheelite family and further create prospective candidates novel applications and/or useful spectral signatures nuclear forensics. However, associated with high-valence in CaWO4 far from understanding. this work, a series scheelite-based materials (Ca1-x-y-zEuxKy□z)WO4 (□...
Solid-state sodium batteries (SSSBs) display great potential in scale energy storage for their safety, cost and sustainability. However, it is a challenge to achieve high ionic conductivity temperature adaptability most sodium-ion solid electrolytes. Here, we demonstrate that Sc 3+ -doped Na 3 Zr 2 Si PO 12 (NASICON) promising electrolyte wide range utilizing SSSBs from 0 50 °C. Optimal 3.4 1.6 0.4 shows superior Na-ion conductivity, up 1.77×10 -3 S cm -1 at room temperature, excellent metal...
Lithium battery, equipped with SiO x as anode, can deliver high discharge capacity, compared to conventional graphite anode. The application of in the lithium however, is challenging due its low conductivity and large volume expansion. In this study, a new sol-gel copolymerization route free toxic solvent designed synthesize interconnected amorphous C y (x~1.5, 1.1≤y≤3.1) nanospheres. Both carbon silica are chemically intertwined via Si-C Si-O-C bonds, showing homogeneous distribution...
