A plasmonic photocatalyst Ag-AgI supported on mesoporous alumina (Ag-AgI/Al(2)O(3)) was prepared by deposition-precipitation and photoreduction methods. The catalyst showed high and stable photocatalytic activity for the degradation and mineralization of toxic persistent organic pollutants, as demonstrated with 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), and trichlorophenol (TCP) under...

This paper reports three dimensional atom probe (3DAP) results of solute clusters and precipitates in early aging stages of Al-Cu(-Li) alloys containing small amounts of Ag and Mg atoms. In an as-quenched Al-1.9Cu-0.3Mg-0.2Ag (at.%) alloy, solute atoms are uniformly dissolved. On aging for 5 s at 180°C, Ag and Mg atoms form co-clusters. These co-clusters do not have well defined shape, but they...

Either metal/metal or metal/non-metal co-doping is one of the most effective methods to modulate visible emission ZnO. In this paper, ZnO, aluminum-doped ZnO (Al-ZnO), aluminum and silver co-doped (Al/Ag-ZnO), nitrogen (Al/N-ZnO) are deposited. Combining substitution zinc ions using Al and/or Ag doping oxygen N expected introduce more interstitial vacancy defects related light in films. The res...

In analogy to our successful "PX2+" insertion reactions, an "AsX2+" insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepared: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from AsI3, PI3 and Ag[Al(OR)4](R=C(CF3)3). The first cation is formally a product of an "AsBr2+" insertion into the Br2 molecule and the latter clear...

A series of Ag-Cu binary mixtures with different Ag/Cu ratios were supported on mordenite with different Si/Al ratios and were subsequently reduced under hydrogen in the temperature range 323K – 473K. Ag and Cu K-edge X-ray Absorption Spectroscopy (XAS) was conducted on these systems in-situ to monitor the reduction species formed and the kinetics of their reduction. In-situ XANES clearly demon...
