A facile and fast ethylene glycol combustion strategy was developed to the synthesis of three-dimension (3D) mesoporous ZnCo₂O₄ architectures. It was found that the volume of colloidal silica employed in the combustion system exerts a profound impact on the specific surface area (SSA) and pore volume of 3D porous ZnCo₂O₄. The SSA and pore volume of 3D mesoporous ZnCo₂O₄–400 could reach up to 130 m² g⁻¹ and 0.641 cm³ g⁻¹ when 400 μL of colloidal silica was used in the combustion system. When used as the LIB's anodes, the 3D mesoporous ZnCo₂O₄–400 could show high reversible capacity and superior cycling performance. The excellent performance is attributed to the high SSA and abundant mesoporous structures in the 3D mesoporous ZnCo₂O₄–400 architectures. The present work not only offers a novel synthetic route towards 3D mesoporous ZnCo₂O₄ but also demonstrates the vast prospect of 3D mesoporous ZnCo₂O₄ as the anode material for Li-ion batteries (LIBs).

开发了一种快速简便的乙二醇燃烧策略，以合成三维（3D）介孔ZnCo ₂ O ₄结构。发现在燃烧系统中使用的胶体二氧化硅的体积对3D多孔ZnCo ₂ O ₄的比表面积（SSA）和孔体积具有深远的影响。当在燃烧系统中使用400μL胶态二氧化硅时，3D介孔ZnCo ₂ O ₄ –400的SSA和孔体积可分别达到130 m ² g ^-1和0.641 cm ³  g ^-1。当用作LIB的阳极时，3D介孔ZnCo ₂ O ₄–400可显示出高可逆容量和出色的循环性能。出色的性能归因于3D介孔ZnCo ₂ O ₄ –400体系结构中的高SSA和丰富的介孔结构。目前的工作不仅为3D介孔ZnCo ₂ O ₄提供了一条新颖的合成途径，而且证明了3D介孔ZnCo ₂ O ₄作为锂离子电池（LIBs）的负极材料的广阔前景。
