Up for a promotion: By combining high-angle annular dark-field scanning transmission electron microscopy analysis and DFT calculations, the effect of a Ni promoter on the 1D morphology of the NiWS phase supported on amorphous silica-alumina (ASA) is revealed and rationalized. The addition of the Ni promoter induces the observed morphology effect in a catalytically active system relevant for industrial application. TOF=Turnover frequency.
