Gold nanorods etching as a powerful signaling process for Fe 3+ could catalyze the oxidation of AuNRs by H 2 O 2. First, Cl and Br ions in HCl and CTAB form complexes with Au 0, resulting in reducing the redox potential of Au + /Au. Then, the Fe 3+ decomposes H 2 O 2 to generate HO 2 and Fe 2+ simultaneously. Then Fe 2+ decomposes H 2 O 2 to produce HO and regenerates Fe 3+.

Surface Structure and Catalytic Performance of Ni-Fe Mar 24, 2014 · Abstract. Catalysts 16Ni Fe/Al 2 O 3 (is 0, 1, 2, 4, 6, 8) were prepared by incipient wetness impregnation method and the catalytic performance for the production of synthetic natural gas (SNG) from CO hydrogenation in slurry-bed reactor were studied. The catalysts were characterized by BET, XRD, UV-Vis DRS, H 2-TPR, CO-TPD, and XPS, and the results showed that the introduction of
Jun 22, 2007 · The basic structural motif of the model, which is closely related to the Baker-Figgis -Keggin cluster (), consists of 13 iron atoms and 40 oxygens ().The central tetrahedrally coordinated Fe is connected by 4-oxo bridges to 12 peripheral octahedrally coordinated Fe atoms arranged in edge-sharing groups of three.The 2- to 6-nm ferrihydrite nanoparticles can then be described as a three mp-169:C (trigonal, R-3m, 166) - The Materials ProjectC is rhombohedral graphite structured and crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three C sheets oriented in the (0, 0, 1) direction. C is bonded in a trigonal planar geometry to three equivalent C atoms. All CC bond lengths are 1.43 Å.
Ni3S2 is Hazelwoodite structured and crystallizes in the trigonal R32 space group. The structure is three-dimensional. Ni+1.33+ is bonded to four equivalent S2- atoms to form a mixture of distorted edge and corner-sharing NiS4 tetrahedra. There are two shorter (2.25 Å) and two longer (2.28 Å) NiS bond lengths.
