Summary: Zirconium phosphate materials are promising adsorbents for removing metal ions from harsh conditions. However, their layered structure often collapses under strong acidic conditions, reducing their industrial efficiency. In this study, we propose two methods to improve the acid tolerance of zirconium phosphate materials by intercalating aza-18 crown 6 ethers. These methods help retain the layered structure and enhance the stability of the materials, making them effective in selectively capturing metal ions.

Summary: A durable carbon anode for high-energy-density potassium-ion full cells was constructed using a preferential pyrolysis strategy. By utilizing volatilization of S and N from a pi-pi stacked supermolecule, the anode introduced low-potential active sites of sp(2) hybridized carbon and carbon vacancies, resulting in a low-potential vacancy-adsorption/intercalation mechanism. The as-prepared carbon anode exhibited a high capacity of 384.2 mAh g(-1) (with 90% capacity below 1 V vs. K/K+) and a high energy density of 163 Wh kg(-1) in the potassium-ion full battery. Moreover, the abundant vacancies of carbon improved cycling stability over 14,000 cycles (8,400 hours). This work provides a new synthesis approach for durable carbon anodes with high energy densities in potassium-ion full cells.

Summary: Modulating the electronic asymmetricity of catalysts is a new approach to improve electrocatalytic performance, but controlling the degree of asymmetry in heterostructured catalysts at the atomic level is still challenging. In this study, Ru nanoclusters were anchored on carbon materials doped with controllable N functional groups to optimize the electronic asymmetricity for efficient hydrogen evolution reaction (HER). By tailoring the type of N dopants, particularly pyrrolic-N, the electronic interaction between Ru and N species was manipulated, resulting in Ru-based heterostructures with excellent HER activity in basic media. Spectroscopy experiments and simulations confirmed that the asymmetric distribution of surface electrons in Ru-based heterostructures enhanced H2O adsorption and dissociation at positively charged interfacial Ru sites, and promoted hydrogen adsorption at negatively charged surface Ru sites, optimizing the elementary steps in the basic HER process. These findings provide crucial insights for the design and fabrication of advanced catalysts.

Summary: To produce hydrogen through seawater splitting at higher current densities, active and robust catalysts are necessary to overcome challenges such as chloride corrosion, chlorine evolution, and catalyst poisoning. A core-shell heterostructure, composed of amorphous NiFe hydroxide layer-capped Ni3S2 nanopyramids grown directly on a nickel foam skeleton, was prepared to enhance oxygen evolution reaction (OER) performance. The catalyst exhibited an anodic current density of 1000 mA cm(-2) at an overpotential of 341 mV in 1.0 m KOH seawater, with improved chemical stability and corrosion resistance. Additionally, a nanopyramid-coated Ni3S2 with FeNi2P (NiS@FeNiP/NF) also showed enhanced hydrogen evolution reaction (HER) activity in the same seawater condition. The combination of NiS@FeNiP/NF and NiS@LDH/NF demonstrated potential for efficient hydrogen production from seawater.
