Abstract The electrochemical conversion of nitrate to ammonia is a way eliminate pollutant in water. Cu-Co synergistic effect was found produce excellent performance generation. However, few studies have focused on this high-entropy oxides. Here, we report the spin-related nitrate-to-ammonia using oxide Mg 0.2 Co Ni Cu Zn O. In contrast, Li-incorporated MgCoNiCuZnO exhibits inferior performance. By correlating electronic structure, that spin states are crucial for pair with high O can...

Highly reversible Mg battery chemistry demands a suitable electrolyte formulation highly compatible with currently available electrodes. In general, conventional electrolytes form passivation layer on the anode, requiring use of MgCl2 additives that lead to severe corrosion cell components and low anodic stability.

Recently, our group reported an LSB cathode made using sulfur spheres that has been spherically templated by MXene nanosheets decorated with CoSe2 nanoparticles, forming a "loose-templating" configuration. It was postulated the minimal restacking of outer nanoparticle-decorated layer helps enable facile ionic transport. However, as do not adhere conformally internal sphere's surface, such...
Metallic magnesium is a promising high-capacity anode material for energy storage technologies beyond lithium-ion batteries.
