Summary: In this study, a series of M-doped Co3O4 materials were grown on a Ni foam substrate, and it was found that doping with Ce significantly enhanced the water and urea oxidation performance, while doping with Ni and Fe reduced the performance. The experimental results suggest that the improved activity of the Ce-doped electrode can be attributed to faster electron transport capacity, higher exposure to active sites, and improved conductivity. This work provides a new approach to enhance the electrocatalytic activity of catalysts through doping strategy.

Summary: Reasonable and efficient electrocatalysts are vital for large-scale water splitting applications. In this study, NiMoO4 nanospheres doped with Cr and P were prepared and demonstrated to be effective electrocatalysts for water splitting. The doping of Cr and P modulated the electronic structure, resulting in an increase in active sites and intrinsic activity. The Cr/P-NiMoO4@NF showed excellent performance in urea oxidation reaction (UOR) and oxygen evolution reaction (OER) due to the doping effect. The improved electrochemical performance was attributed to accelerated electron transfer rate, increased exposure of reaction sites, and improved metal properties. The research provides a novel idea for the development of low-cost and robust electrocatalysts for UOR and OER.

Summary: In this work, a double design host and guest strategy is proposed to enhance the electrochemical properties of sulfur electrodes in sodium ion storage. The V2O3 adsorbent immobilizes sulfur species, while the selenium dopant improves the electronic conductivity and redox conversion of sulfur cathodes. The synergistic effect between the V2O3 adsorbent and selenium dopant inhibits the shuttle effect and improves the redox kinetics, resulting in greatly enhanced Na-ion storage properties of sulfur cathodes. The as-designed sulfur cathode exhibits excellent rate capability of 663 mA h g(-1) at 2.0 A g(-1) and exceptional cyclability of 405 mA h g(-1) over 700 cycles at 1.0 A g(-1).

Summary: High thermal stability and sluggish absorption/desorption kinetics are limitations for using MgH2 as a hydrogen storage medium. Introducing a suitable catalyst, such as the novel nanoparticulate ZrNi, can significantly improve the hydrogen storage properties. The catalytic reaction of nano-ZrNi during the first de-/hydrogenation cycle forms active species that enhance the breaking and rebonding of H-H bonds and provide multiple hydrogen diffusion channels, leading to remarkably improved hydrogen absorption and desorption capabilities.
