%X The binder jetting printing technique enables in situ impregnation of alumina using a Ni(NOl<sub>3</sub>)l<sub>2</sub>-containing ink (NI), facilitating omission of impregnation. NI was compared to wet impregnation (WI). Full characterization by quasi-in situ XPS, XAS and TPR revealed the presence of Ni as NiAll<sub>2</sub>Ol<sub>4</sub> spinel. TPR analysis identified surface NiO and NiAl<sub>2</sub>Ol<sub>4</sub> species with facilitated reduction by NI, in addition to the respective species in bulk form. Post-processing affects active site accessibility by coverage. 3D printing limited the Ni loading, but XPS revealed higher metal dispersion by NI. COl<sub>2</sub> hydrogenation confirmed active Ni/All<sub>2</sub>Ol<sub>3</sub> catalysts with enhanced activity by NI.
