The present disclosure provides an active zinc-based catalyst and a preparation method thereof, and use in catalyzing a rearrangement reaction of ibuprofen. The active zinc-based catalyst includes a carbon-based fiber material and nano-zinc oxide supported on a fiber surface of the carbon-based fiber material. The active zinc-based catalyst is introduced with the carbon-based fiber material, and the carbon-based fiber material is capable of increasing a specific surface area of the catalyst, thereby improving a dispersion degree of zinc oxide, increasing the number of catalytic active sites, and significantly improving a catalytic activity. Meanwhile, due to a certain mechanical strength, the carbon-based fiber material is capable of improving a mechanical strength of the catalyst, making the catalyst exist stably in ketal fluid, maintaining a stable morphology of the catalyst, and avoiding or inhibiting reduction of the catalytic active sites, thereby ensuring a catalytic stability.
