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.

Doped-up cobalt: Cobalt nanoparticles are supported on the nitrogen-doped ordered mesoporous carbon (OMC), and its autoreduction behavior on carbon substrates is greatly improved owing to the formation of uniform cobalt particles. The autoreduced catalysts demonstrate an increasing catalytic activity in the Fischer–Tropsch synthesis.

Architecture on the nanoscale: Self-assembled MFI zeolite nanocrystals are synthesized by a simple hydrothermal pathway combining mesopores and micropores in the framework. Hierarchical porosity of this catalyst results in improved catalytic performance for the synthesis of disulfides.

Supporting role: TiO2-SBA composites were used as supports for CoMo-based catalysts, which combine the adequate textural properties of SBA-15 and the dispersive effect of TiO2 on the active phase. An optimum conversion of thiophene hydrodesulfurization (HDS) is obtained for the catalyst with 20 wt % TiO2, which outperforms its TiO2- and SBA-15-supported homologues.

In the lactone zone: A new catalytic system for the dehydrogenative lactonization of diols in aqueous media is developed. By using a water-soluble dicationic iridium catalyst bearing 6,6′-dihydroxy-2,2′-bipyridine as a functional ligand, highly atom economical and environmentally benign synthesis of various lactones is achieved. The recovery and reuse of the catalyst by a simple procedure is also accomplished.
