Summary: The performance of precious metal (Pt, Pd, Rh, and Ir) trimetallic single-cluster electrocatalysts (UxVyWz-NG) in oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) was investigated using density functional theory calculations. Pt, Pd, and Ir were found to have significant effects on ORR, OER, and HER, respectively. The Pt-3-NG, Pd-3-NG, and Ir-3-NG showed the lowest overpotentials among all UxVyWz-NG combinations. These findings suggest that precious trimetallic single-cluster catalysts exhibit better activity than precious metal single atom catalysts. The electronic structure analysis revealed strong hybridization between O-2p and Pt-3d orbitals in the OH adsorbed Pt-3-NG system, facilitating the electrocatalytic reactions. These results are important for the rational design of high-performance trimetallic catalysts.

Summary: High-entropy layered double hydroxides (HE-LDHs) are promising electrocatalysts for OER due to their high-entropy effect and the cocktail effect. However, their catalytic activity and stability are still unsatisfactory. In this study, we designed FeCoNiCuZn LDHs with rich cation vacancies, which exhibited low overpotentials and excellent stability. DFT calculations confirmed that the cation vacancies enhanced the intrinsic activity of HE-LDHs by optimizing the adsorption energy of OER intermediates.

In this study, we synthesized an OER electrocatalyst by loading vanadium-iron-nickel trimetallic hydroxide nanosheets on a VO(OH)(2) substrate, which exhibited excellent catalytic performance and stability compared to commercial IrO2 and other non-noble metal catalysts. Interphase ionic migration and vanadium ion migration were observed, introducing oxygen vacancies and improving electrical coordination and conductivity. DFT calculations further confirmed the role of vanadium migration in lowering the energy barrier of water-splitting.

Summary: Developing heterostructures in nano-electrocatalyst, such as the Ru@RuO2 heterostructures synthesized through pyrolysis of Ru-MOF, has shown remarkable electrocatalytic performance for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in pH-universal electrolytes. The ultrasmall size and hierarchical porous structure of the heterostructures provide abundant heterointerfaces and highly active sites, leading to ultralow overpotentials and improved reaction kinetics. Theoretical calculations suggest that charge rearrangement and electron conduction intensification at the Ru-RuO2 heterointerfaces optimize the adsorption behavior of reaction intermediates.

Summary: In the context of global energy transition and environmental concerns, electrochemical conversion of carbon dioxide (CO2) to valuable chemicals using clean renewable electricity has emerged as a promising approach for carbon capture, utilization, and storage (CCUS) technology, with potential economic benefits. However, the development of efficient and stable electrochemical CO2 reduction (ECO2R) electrolyzers to fully exploit the catalytic potential remains a challenge that has not received sufficient attention. This review summarizes the progress in ECO2R reactors, including their structural characteristics and electrochemical performance, and discusses the current challenges and limitations in CO2RR reactor design. The goal is to provide insights into the advancements in ECO2R electrolyzers for large-scale industrial applications of ECO2R.

Summary: Single-crystal-to-single-crystal (SCSC) phase transformation is essential for the controllable synthesis of advanced materials. However, understanding the atomic-scale mechanisms during SCSC transformation remains a challenge due to the lack of direct experimental probes. In this study, using in-situ transmission electron microscopy, the nucleation and growth mechanisms of a hexagonal phase in a monoclinic matrix during a heating-induced structural transformation were observed. The findings provide crucial insights into the microscopic mechanisms and kinetics of solid-state phase transitions.

Summary: Current polymer nanocomposites for energy storage suffer from low discharged energy density and efficiency at high temperature. To solve this problem, polyetherimide (PEI) nanocomposites filled with core-shell structured nanoparticles are developed, which consist of a PLZST antiferroelectric core and an Al2O3 shell. The PLZST core provides a wide temperature range of low remnant electric displacement, improving the electric displacement-electric field loops of the nanocomposites. The Al2O3 shell with similar dielectric constant to the PEI matrix and high thermal conductivity enhances breakdown strength and suppresses conduction loss, resulting in an ultrahigh discharged energy density of 10.20 J cm(-3) at 150 degrees C and a large efficiency of 83.5%.

Summary: Rechargeable Zinc battery technologies are considered promising for large-scale energy storage. However, the polarity of water molecules leads to the deterioration of both the zinc metal anode and cathode. In this study, a lean-water electrolyte was developed by replacing 90% of the water sheath with 1,3-propanediol (PDO) molecules. The results showed that this electrolyte effectively suppressed hydrogen evolution reaction and inhibited zinc dendrite growth, leading to high capacity and long lifespan in zinc-ion batteries.
