A nanoflower-like nickel foam supported Co₃O₄ (Co-NF) monolithic catalyst was synthesized via a green and facile electro-deposition strategy. The optimized Co-NF presents much higher catalytic activity per Co₃O₄ loading, ca. 6.7 × 10⁻⁴ mol/(g_Co3O4·s) at 220 °C and exhibits a lower activation energy of 46 kJ/mol compared with powder Co₃O₄. It also exhibited good stability (e.g. >80% propane conversion) for 40 h at 350 °C and a GHSV of 30,000 mL/(g_cat·h) without any notable decrease. The 3D hierarchical microstructures with interconnected pore channels, the high Co²⁺ content and the weak CoO bond strength of Co-NF-300 s were considered key factors responsible for the good activity and stability in the propane catalytic total oxidation.

纳米花状镍泡沫负载的Co ₃ O ₄（Co-NF）整体催化剂是通过绿色且简便的电沉积策略合成的。最佳的Co-NF在每添加Co ₃ O _4时表现出高得多的催化活性。在220°C下为6.7×10 ^-4  mol /（g _Co3O4 ·s），与粉末Co ₃ O ₄相比，其活化能更低，为46 kJ / mol 。它还在350°C下显示40个小时的良好稳定性（例如，丙烷转化率> 80％），并且GHSV为30,000 mL /（g _cat ·h），并且没有明显降低。具有相互连通的孔道，高Co ²⁺的3D分层微观结构Co-NF-300 s的含量和弱的Co O键强度被认为是丙烷催化总氧化反应的良好活性和稳定性的关键因素。
