摘要

This paper studies the preparation of Pt-based bimetallic (PtFe, PtSn, PtIn and PtGa) catalysts supported on carbon nanotubes for the citral hydrogenation by deposition-reduction in liquid phase and their comparison with the conventional impregnation method (CI). When conventionally impregnated, the selectivity to unsaturated alcohols (UA) highly increased from the monometallic to the bimetallic samples, whereas for liquid phase reduced ones, the selectivity to UA was rather similar for both Pt and bimetallic samples except for PtFe ones and for the PtSn catalyst treated treated with N-2. The results were explained taken into account the intimate interaction achieved between the metals according to the preparation method and the formation of Pt-promotor complexes in the impregnating solution.
