Summary: A composite supercapacitor electrode material, MnO2 decorated cobalt-iron Prussian blue analogue (CoPBA), has been successfully designed and fabricated through a facile precipitation method. The encapsulation of MnO2 onto CoPBA surface improves electrochemical performances by increasing electrical conductivity and specific capacitance. The maximum specific capacitance of CoPBA@MnO2 reaches 945F g(-1) at 1 A/g, which is 3.2-fold and 6.7-fold higher than that of pure CoPBA and MnO2, respectively. This study provides a valuable reference for the design of high performance electrode materials with simplicity and low cost.

Summary: Potassium-ion batteries (PIBs) have recently emerged as an alternative to lithium-ion batteries for large-scale grid energy storage, thanks to their cost-effectiveness and high theoretical energy density. However, the scarcity of appropriate high-capacity cathode materials is a critical challenge for PIBs. Prussian blue analogs (PBAs) have gained attention due to their simple synthesis and stable framework that allows for the insertion/extraction of large-size K+. This review provides an overview of current research progress on PBAs as cathode materials in nonaqueous PIBs, including crystal structure, electrochemical reaction mechanisms, optimization strategies, and the transition to commercial production.

Summary: Among energy storage systems, symmetric aqueous batteries (SABs) are gaining attention due to their low cost, convenience, and safety. However, there is a limited selection of bipolar materials for SABs and practical applications are rare. This study utilizes Prussian blue analogues (PBAs) with bipolarity to construct SABs, resulting in improved structural stability and enhanced cyclability. Various application scenarios, such as fibrous SABs, low-temperature SABs, and seawater SABs, have been explored with different electrolytes. The study presents a universal strategy for constructing practical SABs using PBAs materials.

Summary: We report on the fabrication of three-dimensional hierarchical core-satellite SiO2@monomicelle spherical superstructures through a previously unexplored monomicelle interfacial super-assembly route. The ultrathin single layer of monomicelle subunits with hexagon-like regular discontinuous distribution on solid spherical interfaces can be achieved, and the number of monomicelles on colloidal SiO2 interfaces can be quantitatively controlled. This strategy provides a controllable way for building multiscale hierarchical regular micro- and/or macroscale materials and devices.

Summary: This research utilizes oligopeptides as structure-directing ligands to modulate the self-assembly of POM superstructures via metal-coordination and hydrogen bonded interactions. It is found that changing the N-terminal amino acid on the peptide chain can readily switch the helicity of the nanowheel. Additionally, a delicate balance between Mo-coordination and hydrogen bonds within the internal cavity of the inorganic nanowheels leads to the sequence mediated formation of two unprecedented asymmetrical nanowheel frameworks: {Mo122Ce5} and {Mo126Ce4}.

Summary: Facile and efficient production of ultra-stable metal nanocatalysts based on strong metal-support interactions (SMSI) was achieved through ultrasonication in water at ambient conditions, which generated abundant active intermediates, Ti3+ ions, and oxygen vacancies to induce SMSI overlayer formation. The degree of encapsulation could be controlled by the reducibility of solvents and ultrasonication parameters. This approach can be extended to other metal oxide supports and noble metal nanoparticles, leading to enhanced performance in hydrogenation reactions and CO2 conversion.

Summary: We report polydopamine-derived carbons with tailorable sub-5 angstrom micropore orifices and larger microvoids for olefin/paraffin separation. The sub-5 angstrom micropores allow the entry of olefins while excluding paraffins, achieving precise discrimination. The larger microvoids enable high ethylene and propylene capacities under ambient conditions. This study opens an avenue to exploit the sub-5 angstrom micropores in carbon for desirable size-exclusion effect.

Summary: High-capacity cathodes (LiNi0.8Mn0.1Co0.1O2, NMC811) have the potential for vehicle electrification due to their high gravimetric energy density, but their electrochemical performance depends on the stability of the cathode electrolyte interphase (CEI). A conformal LiF layer formed on the NMC811 electrode surface through an in situ ion-exchange metathesis process improves the electrochemical performance by stabilizing the CEI. This finding could pave the way for enhancing the electrochemical performances and cycling stability of high-capacity cathodes by reengineering the CEI.

Summary: Developing a powerful bifunctional catalyst is crucial for achieving future carbon neutrality by reducing energy consumption in the chemical industry. This study synthesizes mesoporous zeolite-encapsulated palladium nanoparticles (Pd@meso-ZSM-5) using emulsification-demulsification and dry-gel transformation methods, which exhibit remarkable catalytic performance in the one-pot multiple tandem reaction of cyclic ketones to bicyclic alkanes. Unlike traditional two-step synthesis routes, Pd@meso-ZSM-5 efficiently produces bicyclic alkanes instead of monocyclic alkanes, due to the sufficient space for large molecular intermediates provided by mesoporosity and the promoting effect of the acid-Pd interface on intermediate conversion.

Summary: The methylation of imidazolium-based room temperature ionic liquids (RTILs) paired with [Tf2N](-) anion results in an unexpected increase in viscosity, while the viscosity decreases when the methylated imidazolium is paired with [B(CN)(4)](-) anion. The compensated Arrhenius formalism (CAF) is used to study the viscosity observations, focusing on the activation energy and entropy of activation. The results show that the activation energy increases with methylation for [Tf2N](-), but decreases for [B(CN)(4)](-).

Summary: The electrochemical deposition of rare earth metals at room temperature has gained increasing attention for its energy efficiency advantage over traditional processes. However, the formation of a passivating fluoride layer during electrolyte decomposition is often overlooked, leading to the rapid decay of deposition current and hindering practical application. To address this issue, a fluorine-free electrolyte utilizing borohydride anion was demonstrated, enabling efficient electrodeposition of rare earth metals without passivation effect. Synergetic effects between rare earth borohydride and lithium borohydride were observed, promoting dissociation and improving ionic conductivity and electrochemical performance.
