Summary: In this study, a hierarchical nanostructured electrocatalyst with enriched amorphous/crystalline interfaces was reported for high-efficiency alkaline hydrogen evolution reaction (HER). The electrocatalyst consisted of amorphous/crystalline (Co, Ni)(11)(HPO3)(8)(OH)(6) homogeneous hierarchical structure with an ultra-low doped Pt. Due to the structural flexibility of the amorphous component, extremely low Pt was stably doped on it via a simple two-phase hydrothermal method. The obtained catalyst exhibited an exceptionally high mass activity (39.1 mA mu g(Pt)(-1)) at 70 mV.

Summary: A 1D/3D hierarchical heterostructure electrocatalyst, consisting of NiMoO4 nanorod arrays inserted with Ni(OH)(2) nanoflowers, was synthesized via hydrothermal-calcination and rapid electrodeposition method. In an alkaline solution, the obtained Ni(OH)(2)-NiMoO4/NF electrocatalyst exhibited outstanding HER activity, with a low overpotential of 90 mV at 10 mA cm(-2), a low Tafel slope of 86.9 mV dec(-1), and high stability. The unique structure increased the specific surface area and facilitated the release of air bubbles and the penetration of electrolytes. The simple synthesis process and excellent electrocatalytic performance demonstrated the great potential of Ni(OH)(2)-NiMoO4/NF as a replacement for noble metal-based catalysts in HER.

Summary: Adding reactive dopant metals to selective host metals is a common strategy to enhance catalytic reactivity without sacrificing selectivity. This study focuses on indium, an exotic metal highly selective in CO2 hydrogenation to methanol, and describes the synthesis and properties of Pd-In alloys with different aggregation states of Pd. These alloys show unique catalytic behaviors, with Pd promoting both reaction rate and methanol selectivity, especially when present in small clusters. The study suggests that conventional synthesis methods for dilute-limit and single-atom alloy catalysts can be extended to non-coinage metal hosts, although the role of ensemble size may vary significantly.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
