The nanogold particles are first dispersed in cellulose solution, then a hollow fiber nanogold catalyst membrane is prepared using electrospinning technology. The physicochemical properties and CO low-temperature selective oxidation reaction activity of the catalyst membrane are measured and evaluated.After the experiment, we will obtain a hollow fiber nanogold-based catalyst membrane with high surface area, good stability and activity, which can be used in low-temperature selective oxidation of CO. By adjusting the reaction conditions and gas phase composition, considering the formation and reduction process of catalyst surface oxide species, we will optimize the catalytic system to obtain better reaction performance.Key words: hollow fiber; nanogold; catalyst membrane; selective oxidation reaction; hydrogen-rich atmosphere.
