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+.

Total aqueous Fe concentrations were determined in 0.22- µm nylon filtrates (all time points) and 0.025-µm cellulose filtrates (at 0, 3, and 7 days) using ICP-OES. 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
