Summary: In this study, multishelled hollow structures (HoMSs) with different shell numbers, thicknesses, pore sizes, surface areas, and void sizes were successfully synthesized using carbon microspheres as a hard template and two different strategies: two-step strategy (TsS) and one-step strategy (OsS). The ZnO@TiO2 HoMSSs synthesized by OsS (triple shelled) exhibited excellent potassium storage capacity, rate capability, reversibility, and cyclic life in aqueous alkaline batteries, thanks to the thinner shell, larger pore size, high surface area, and bigger voids that provided a distinctive buffering zone for charge-discharge and improved the structural stability and cycling stability during the OH- intercalation/de-intercalation process.

Summary: In this study, Ni3S2 materials were in-situ grown on nickel foam using the one-step reflux method, and a PPy conductive film was coated on the surface of Ni3S2 materials by electrodeposition to prepare self-supporting Ni3S2@PPy composites on nickel foam. The content of PPy on the surface of the Ni3S2 materials was controlled by adjusting the number of cyclic voltammetry cycles during the electro-deposition process. The Ni3S2@PPy composites exhibited excellent lithium storage performance when one cycle of cyclic voltammetry was applied. Coating with PPy significantly improved the decline of Ni3S2 electrode capacity after 50 cycles and enhanced the stability during later cycles.

Summary: A surface modification strategy is developed to sequentially deposit ultrathin CoOx overlayer and Ni single atoms on Ti-doped alpha-Fe2O3 nanorods. The collaboration of CoOx overlayer and Ni single atoms improves the photo-electrochemical performance for water splitting, with a photocurrent density over three times that of Ti:Fe2O3. The passivation effect of CoOx overlayer reduces surface carrier recombination, while the catalysis effect of Ni single atoms accelerates water oxidation kinetics.

Summary: Strain engineering is used to regulate the binding of intermediates and modify catalytic behavior on nanocatalysts. In this study, Pd-based nanooctahedrons coated with two Ir overlayers were constructed and subject to different treatments to achieve different surface strains. It is shown that the catalytic performances of these nanocatalysts display a volcano-shaped curve against strains toward the hydrogen evolution reaction. Specifically, o-Pd/Ir-1.7% NPs exhibit superior catalytic performance, making it one of the most active electrocatalysts reported to date.

Summary: Designing robust and highly efficient electrocatalysts for seawater splitting is crucial for hydrogen production. In this study, Ru nanospecies were implanted into a Ni/Fe-oxalate solid solution with high-indexed facets, resulting in an effective and novel-structured catalyst (Ru-(Ni/Fe)C2O4). Experimental and theoretical analyses showed that Ru-(Ni/Fe)C2O4 exhibited extraordinary activities for HER, OER, and HzOR due to the synergistic effect between Ru nanospecies and high-index facets. The electrolyzer assembled with this catalyst achieved a cell voltage reduction to 0.01 V at 10 mA cm-2 for HER-HzOR coupling seawater splitting and remained stable under 500 mA cm-2 at 80 degrees C for 50 hours, approaching the requirements for quasi-industrial electrolysis. This work provides a guideline for preparing multifunctional electrocatalysts and offers an effective strategy for developing seawater electrolysis for a hydrogen economy society.
