Peek-a-boo, Ni Cu: Silica-supported, bimetallic Cu–Ni nanomaterials with different ratios of Cu to Ni are prepared by incipient wetness impregnation without a separate calcination before reduction. TEM, XRD, and X-ray absorption spectroscopy are used to follow the reduction and alloy formation in situ. A strong interaction is found between Cu and Ni species, which results in improved reducibility of the Ni species compared with monometallic Ni.
