However, the non–uniform deposition/stripping behavior of Mg metal hinders the practical application of RMBs. This study demonstrates that the designed interfacial electric field effect, driven by a copper phthalocyanine (CuPc) conductive interlayer, enhances the kinetics and stability of the Mg anode. In situ electrochemical impedance spectroscopy coupled with distribution of relaxation times analysis reveals that the highly delocalized electron cloud network of CuPc establishes a low-energy-barrier electron transport pathway, significantly reducing charge transfer resistance.

Furthermore, finite element simulations substantiate that the interfacial electric field imparts uniform interfacial charge distribution and homogeneous Mg deposition during plating/stripping processes. Consequently, the symmetric cell with CuPc@Mg achieves an ultra-long lifetime (1,400 h at 5 mA cm<sup>−2</sup>) and a high Coulombic efficiency (99.3%).

The incorporation of SACs typically depends on robust metal-support interactions, which stabilize the single atoms on the support through various unsaturated chemical sites or spatial confinement. A critical challenge lies in precisely modulating the electronic structure and coordination environment of metal atoms. However, current research primarily focuses on single-atom metals, often neglecting the significant role of support materials in SACs. Two-dimensional (2D) atomically thin materials (ATMs) possess unique physicochemical properties and tunable reaction environments, which can modulate catalytic performance via metal-support interactions, positioning them as promising platforms for SAC loading. This paper reviews the recent advancements and the current status of SACs supported on 2D ATMs (SACs@ATMs). The structural design theory and synthesis strategies of SACs@ATMs are systematically discussed. The significance of advanced characterization techniques in elucidating the coordination environment and metal-support interactions is highlighted. Additionally, the reaction mechanisms and applications of SACs in electrocatalytic water splitting are summarized. Finally, the future challenges and opportunities for SACs@ATMs are outlined.
