However, urea electrolysis is predominantly bottlenecked by sluggish reaction kinetics and poor long-term stability, which severely limit its overall efficiency. To address these challenges, a self-supported NiCoMo-based multiphase heterostructure catalyst (NiCo@Ni-CoMoO₄/CWC) was in situ constructed on carbonized wood cellulose (CWC). The built-in electric field and interfacial lattice strain induced by heterointerfaces between NiCo, NiMoO₄, and CoMoO₄ enhance intrinsic activity by regulating the electronic structure and optimizing the adsorption-desorption energies of reaction intermediates. Simultaneously, CWC substrate’s three-dimensional porous structure, superior hydrophilicity, and conductivity provide abundant accessible active sites, facilitate rapid mass/electron transport, and improve structural stability, further boosting catalytic performance. Benefiting from these synergistic advantages, NiCo@Ni-CoMoO₄/CWC exhibits remarkable electrocatalytic performance (<i>E</i> = 1.28 V@100 mA cm^–2 and <i>E</i> = −0.046 V@–10 mA cm^–2). When assembled for urea electrolysis, it achieves an ultra-low cell voltage of 1.44 V at 500 mA cm^–2 with 200 h of exceptional stability. This work not only develops an efficient and sustainable wood cellulose-based electrocatalyst but also provides a feasible strategy for the design of advanced heterostructure catalysts. 2026-09-14T00:00:00Z Dataset Media 10.1021/acs.iecr.6c02603.s003 https://figshare.com/articles/media/Carbonized_Wood_Cellulose-Supported_NiCoMo_Heterostructures_for_Stable_and_Efficient_Urea_Electrolysis/33746039 CC BY-NC 4.0
