abstract
This paper reports on the "in-situ" preparation deposition and reduction of Ni-Cu nanoparticles (NPs) on gamma-Al2O3 as support, using a green and elegant one pot synthesis approach. Pristine and supported Ni-Cu NPs were evaluated as (de)hydrogenation catalysts for the Guerbet reaction of 1-octanol and compared with a classic impregnated and "ex-situ" reduced NiCu on gamma-Al2O3 catalyst. XRD reavealed that the degree of Ni-Cu nano alloying was insignificant in the one pot preparation method, resulting in Ni-Cu nanocomposites, while the degree of nano alloying was resp. low and very high in the pristine nanoparticles (NPs) and the classic impregnated catalyst. The degree of reduction was very similar for both the in situ and ex situ reduction treatments of the supported catalysts as demonstrated by H-2 chemisorption. The "in-situ" prepared supported NiCu NPs showed an enhanced kinetics when compared to the unsupported pristine Ni-Cu NPs, showing a beneficial effect of the metal support interaction, however the classic impregnated catalyst showed overall the best kinetics, selectivity and stability for the Guerbet reaction of 1-octanol.
