A composite cluster composed of Dexter–Silverton structure polyoxometalates (POMs) and porous fluoro-graphdiyne (FGDY) was synthesized and applied for the electrochemical oxygen evolution reaction (OER). Compared with the original POMs and FGDY, the composite cluster Co5.7Ni2.3W12O42(OH)4@FGDY demonstrates superior performance and stability for the electrochemical OER. The composite cluster exhibited high performance for the OER with low potentials and a small Tafel slope. High catalytic activity could be obtained at a high current density. Co5.7Ni2.3W12O42(OH)4@FGDY exhibits excellent catalytic performance and long stability due to its strong electron-transfer ability in the system, higher conductivity, and structural advantage of pores in FGDY. This would open access and guide us to synthesize novel composite clusters based on polyoxometalates and graphdiyne.

复合团簇：Co5.7Ni2.3W12O42(OH)4@fluoro-graphdiyne 作为稳定电极在高电流条件下持续电化学析氧
合成了由 Dexter-Silverton 结构多金属氧酸盐 (POM) 和多孔氟石墨二炔 (FGDY) 组成的复合簇，并将其应用于电化学析氧反应 (OER)。与原始 POM 和 FGDY 相比，复合团簇 Co 5.7 Ni 2.3 W 12 O 42 (OH) 4 @FGDY 表现出优异的电化学 OER 性能和稳定性。复合簇对低电位和小塔菲尔斜率的 OER 表现出高性能。在高电流密度下可以获得高催化活性。Co 5.7 Ni 2.3 W 12 O 42 (OH) 4@FGDY由于其在体系中具有较强的电子转移能力、较高的电导率以及FGDY中孔隙的结构优势，表现出优异的催化性能和长期稳定性。这将开放访问并指导我们合成基于多金属氧酸盐和石墨二炔的新型复合簇。
