The ZnO/ZnCo₂O₄ sample features an ordered assembly of nanocrystals with a size of 30 nm forming two dimensional (2D) nanosheets, and ZnO-ZnCo₂O₄ heterojunctions are uniformly distributed. The physicochemical properties of ZnO/ZCO heterostructures were systematically studied by combining experiments and density functional theory (DFT) calculation. The heterojunction configuration of ZnO and ZnCo₂O₄ produced an interfacial charge redistribution and strong electronic interaction, resulting in the enhanced electrocatalytic performance towardRSC advances1368-1381https://www.ebi.ac.uk/biostudies/studies/S-EPMC12768403biostudies-literature2D assembled ZnO/ZnCo<sub>2</sub>O<sub>4</sub> heterostructures as efficient electrocatalysts for electrochemical detection of ofloxacin in water: experimental and DFT study.PMC12768403Vinh Hoang TPhan MHLe ATThi Huong Mai VThanh Vinh NXuan Dinh NNguyen NHMinh Tung Lfalse2D assembled ZnO/ZnCo<sub>2</sub>O<sub>4</sub> heterostructures as efficient electrocatalysts for electrochemical detection of ofloxacin in water: experimental and DFT study.In this work, assembled ZnO/ZnCo₂O₄ heterostructure nanosheets (ZnO/ZCO) were successfully synthesized through a rapid one-step microwave-assisted hydrothermal method.
