Ultrathin two-dimensional (2D) metal-organic framework (MOF) nanosheets have been regarded as very promising electrocatalysts, although more efforts need to be devoted to improve their electrocatalytic activity. Here, we have developed ultrathin 2D nanosheet-assembled [Ni3(OH)2(PTA)2(H2O)4]·2H2O (Ni-MOF, PTA = p-benzenedicarboxylic acid) hierarchical flowers, which demonstrate superior electrocatalytic activity and excellent stability for the glucose oxidation reaction (GOR). The ultrathin 2D nanosheet-assembled flower-like nanostructure can provide interconnected open pores, accounting for its high electrocatalytic performance. Additionally, most of the ultrathin 2D nanosheets are in close contact with each other, making the ultrathin 2D nanosheets more stable. Furthermore, the electrocatalytic activity of the Ni-MOF flowers can be adjusted by doping Zn into the framework.
超薄二维(2D)金属有机骨架(MOF)纳米片被认为是非常有前途的电催化剂,尽管需要进一步努力来提高其电催化活性。在这里,我们开发了超薄二维纳米片组装的[Ni3(OH)2(PTA)2(H2O)4]·2H2O(Ni-MOF,PTA = 对苯二甲酸)分级花,其对葡萄糖氧化反应(GOR)表现出优异的电催化活性和稳定性。超薄二维纳米片组装的花状纳米结构可以提供相互连接的开放孔,这是其具有高电催化性能的原因。此外,大多数超薄二维纳米片彼此紧密接触,使超薄二维纳米片更加稳定。此外,通过在骨架中掺杂 Zn 可以调节 Ni-MOF 花的电催化活性。
