Abstract: PtCox bimetallic nanoparticles(NPs) supported on tannin-grafted collagen fiber(CF-BT) have been prepared via a novel synthetic strategy, and applied for catalytic hydrogenation of cinnamaldehyde(CAL), a typic unsaturated aldehyde. The catalysts were systematically and specifically characterized by means of XRD, XPS, TEM-EDX and SEM to clarify the structure-property correlation. It was found that the PtCox/CF-BT catalysts exhibited significantly enhanced catalytic activity and desirable stability in catalytic hydrogenation of CAL, which is ascribed to the synergistic interaction between bimetallic components, the effective dispersion, the anchoring role of CF-BT matrix on bimetallic NPs, as well as the lower mass transfer resistance of the matrix.
