Abstract
Using collagen fiber as the carbon source, the collagen fiber was grafted with bayberry tannin (CF-BT) to adsorb Pd2+, and carbon fiber-loaded Pd nanocatalyst (Pd/C) was prepared after carbonization and hydrogen reduction. Through field emission scanning electron microscopy (FESEM) ), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), etc. The catalyst was characterized. The results showed that the prepared Pd/C catalyst retained the regular fibrous structure of collagen fibers. , Pd nanoparticles are uniform in size and highly dispersed, with an average particle size of 2.92nm. This catalyst is used in the catalytic hydrogenation reaction of propylene alcohol. Under 308.0K and 1.0MPa hydrogen pressure, the propylene alcohol conversion rate (TOF) is as high as 2460h-1 , the catalyst repeats
