Developing efficient and economical electrocatalysts for hydrogen generation at high current densities is crucial advancing energy sustainability. Herein, a self-supported evolution reaction (HER) electrocatalyst rationally designed prepared on nickel foam through simple two-step chemical etching method, which consists of Pt quantum dots (PtQDs) coupled with nickel-iron layered double hydroxide (NiFe LDH) nanosheets (named PtQDs@NiFe LDH). The characterization results indicate that the introduction PtQDs induces more oxygen vacancies, thereby optimizing electronic structure LDH. This modification enhances conductivity accelerates adsorption/desorption kinetics intermediates in LDH, ultimately resulting exceptional catalytic performance HER large densities. Specifically, LDH delivers 500 2000 mA·cm-2 remarkably low overpotentials 92 252 mV, respectively, markedly outperforming commercial Pt/C (η500 = 190 η2000 436 mV). Moreover, when employing NiFe precursor catalyst as anode cathode, an overall water electrolysis system, only 1.66 V 2.02 are required to achieve mA·cm-2, while maintaining robust stability 200 h. study introduces feasible approach developing industrial-scale

Noble-metal single-atom catalysts (SACs) have arisen as a research hotspot in heterogeneous catalysis resulting from superior noble-metal-atom utilization, well-defined catalytic centers, and tunable microenvironments. Recently, the advent rise of noble-metal SACs supported by layered double hydroxides (LDHs) injected fresh vitality vigor into this field. LDHs offer distinct advantages support SACs, such an ordered adjustable crystal structure, two-dimensional structure possessing large specific surface area, facile synthesis with cost-effectiveness, strong co-catalytic metal-support interaction between single atoms. In review, we classified comprehensively outlined current strategies LDHs, conducted in-depth analysis mechanisms underlying each strategy. Subsequently, considering critical role microenvironment affecting their catalytic-related properties, discussed regulation LDH-supported SACs. We also provide introduction to characterization techniques for singe-atom sites Furthermore, diverse applications various fields roles played atoms relevant processes. Finally, delineated challenges future directions development
