Exploring active and durable Ni-based materials with optimized electronic architectural engineering to promote the urea oxidation reaction (UOR) is pivotal for urea-related technologies. Herein a 3D self-supported hierarchical-architectured nanoarray electrode (CC/MnNi@NC) proposed in which 1D N-doped carbon nanotubes (N-CNTs) 0D MnNi nanoparticles (NPs) encapsulation are intertwined into 2D nanosheet aligned on cloth prominently boosted sustained UOR electrocatalysis. From combined experimental theoretical investigations, Mn-alloying can regulate Ni state downshift of d-band center, facilitating Ni3+ species generation prompting rate-determining step (*COO intermediate desorption). Meanwhile, micro/nano-hierarchical configuration N-CNTs encapsulating NPs not only endow strong operational durability against metal corrosion/agglomeration enrich density sites, but also accelerate electron transfer, more intriguingly, mass transfer as result desirable superhydrophilic quasi-superaerophobic characteristics. Therefore, such elegant integration 0D, motifs architecture, resulting CC/MnNi@NC deliver admirable performance, favorably comparable best-performing electrocatalysts reported thus far. This work opens fresh prospect developing advanced via manipulation coupled various energy conversion
