Summary: In this study, a NiFe-based heterostructure catalyst composed of NiFe-based LDH nanosheets and amorphous NiFe-tungstate nanoparticles on a graphene substrate was proposed. The catalyst exhibited superb electrocatalytic activity for oxygen evolution reaction (OER) in an alkaline electrolyte, surpassing the benchmark IrO2 catalyst in terms of overpotential and Tafel slope. Moreover, it showed superior stability and durability compared to IrO2. The hetero-assembly of NiFe-LDH and NiFeWO4 generated more efficient active sites for OER, leading to improved performance.

Summary: In this study, the addition of highly active catalytic precursor TTONC greatly improved the hydrogen storage properties of MgH2. The TTONC-catalyzed MgH2 could absorb hydrogen at room temperature, and its onset dehydrogenation temperature was significantly lower than that of pristine MgH2. It also exhibited good cyclic stability with a high capacity retention rate after multiple hydrogen absorption-desorption cycles. The catalytic mechanism involved the in situ formation of TiH2, which acted as a hydrogen pump to enhance hydrogen diffusion, and the formation of stable CN layers on the surface of MgH2, which inhibited particle fragmentation and agglomeration.

Summary: Sodium tartrate is used as a dual-functional electrolyte additive to improve the reversibility of aqueous zinc-ion batteries. The additive preferentially adsorbs on the zinc surface, coordinates with zinc ions, and promotes uniform zinc deposition on the (002) plane, inhibiting side reactions and dendrite growth. This leads to long-term cycling stability and improved performance of zinc||MnO2 full cells.

Summary: We designed and synthesized a porous organic polymer (POP) with a conjugated and hierarchical structure, which exhibited excellent electrochemical properties as an anode material for sodium-ion batteries (SIBs). Through combined experiments and theoretical computation, we revealed the Na-storage mechanism and dynamic evolution processes of the POP, including a 12-electron reaction process with Na and stable composition and structure evolution during repeating sodiation/de-sodiation processes. This quantitative design for ultrafast and highly durable sodium storage in the POP could benefit the rational design of organic electrode materials with ideal electrochemical properties.

Summary: To stabilize the zinc anode in zinc metal batteries, researchers have developed a controlled electrolytic method using a high dipole moment solvent dimethyl methylphosphonate (DMMP) to create a monolithic solid electrolyte interphase (SEI). This DMMP-based electrolyte generates a homogeneous and robust phosphate SEI (Zn-3(PO4)(2) and ZnP2O6). With the protection provided by this in situ monolithic SEI, the zinc electrode exhibits long-term cycling performance and high Coulombic efficiency in both zinc|zinc and zinc|copper cells. The use of a DMMP-H2O hybrid electrolyte in a full V2O5|zinc battery also results in high capacity retention following a large number of cycles.

Summary: Hierarchical coral spheres of CeO2/ZnO were prepared using a template-free hydrothermal method followed by annealing treatment. The resulting coral spheres exhibited superior acetone sensing, cycling stability, and long-term stability compared to CeO2 or ZnO. By controlling the Ce/Zn ratio, the coral spheres showed the highest response towards 100 ppm acetone at the optimum working temperature of 245°C, reaching up to 145, which was approximately 5.5 times higher than that of ZnO coral spheres. The enhanced gas sensing performance could be attributed to the well-dispersed and assembled CeO2 nanoparticles on the surface of ZnO coral spheres and the heterojunctions between CeO2 and ZnO, which generated abundant oxygen vacancies in the CeO2/ZnO coral spheres.

Summary: Electrocatalytic water splitting is a promising method for green hydrogen production, but the high energy barrier and sluggish kinetics of the anodic oxygen evolution reaction (OER) hinder its large-scale industrial application. Hybrid water electrolysis using two-dimensional (2D) electrocatalysts is considered an effective approach to reduce the cost of electrocatalytic green hydrogen production. This review comprehensively analyzes the advantages, current status, future directions, and feasibilities of hybrid water electrocatalysis by 2D electrocatalysts. It emphasizes the importance of developing matched alternative reactions and stable reactors/devices for efficient hybrid water electrolysis.
