Microfibrous structured Au/Co₃O₄/Al-fiber catalyst to be used for the combustion of ethylene (C₂H₄) traces was developed by hydrothermal growth of Co(OH)₂ nanoarrays onto thin-sheets of Al-fiber followed by solvent-assisted incipient wetness impregnation of Au NPs. Such catalyst supported on the Co(OH)₂/Al-fiber nanoarrays with different morphology exhibits different C₂H₄ conversion under the same combustion reaction conditions. Notably, the Au/Co₃O₄/Al-100 of low Au content provides unique combination of high low-temperature activity and high throughput. It was found that the strong Au-Co₃O₄ interactions over the Au/Co₃O₄/Al-100 catalyst prepared at 100 °C under hydrothermal conditions facilitate oxygen adsorption and activation, thereby enhancing the low-temperature catalytic activity for ethylene combustion.

通过将Co（OH）₂纳米阵列水热生长到Al-纤维薄板上，开发了用于燃烧痕量乙烯（C ₂ H ₄）的微纤维结构Au / Co ₃ O ₄ / Al-纤维催化剂。 Au NPs的溶剂辅助初期湿润浸渍。负载在具有不同形态的Co（OH）₂ / Al-纤维纳米阵列上的这种催化剂在相同的燃烧反应条件下表现出不同的C ₂ H ₄转化率。值得注意的是，Au / Co ₃ O ₄低Au含量的/ Al-100提供了高低温活性和高通量的独特组合。发现在水热条件下于100°C制备的Au / Co ₃ O ₄ / Al-100催化剂上的强Au-Co ₃ O ₄相互作用促进了氧的吸附和活化，从而增强了乙烯的低温催化活性。燃烧。
