AB  - We present the synthesis and photocatalytic properties of mixed-phase TiO2 nanoparticles decorated with silver nanodots obtained by environmental-friendly wet chemical method using low molecular weight chitosan as the silver reducing agent. Structural analysis of synthesized Ag nanoparticles revealed that they crystallized in a rare hexagonal modification. High-resolution transmission electron microscopy study shows that   lt 3-nm hexagonal-Ag nanoparticles are implanted on the surface of   lt 20-nm anatase grains. Compared to Ag-free TiO2 powders, implantation with Ag results in important increase in visible light absorption. The photocatalytic activity of the samples was measured by monitoring decolorization of concentrated textile dye solution (50 mg L-1 of Reactive Orange 16) under simulated solar irradiation of 280 W m(-2). The optimum photocatalytic properties are achieved with 5 wt% of silver. Based on the collected results, the operating mechanism of the degradation process is suggested, and the effects of the silver addition are explained.

AB  - Four silver-based coordination polymers, {[Ag(L1)(2)]NO3}(infinity) (1), {[Ag(L1)(2)]ClO4}(infinity) (2), {[Ag(L2)(2)]NO3 center dot H2O}(infinity) (3) and {[Ag(L2)(2)]ClO4}(infinity) (4), were synthesized using the thiomorpholine-4-carbonitrile (L1) and piperazine-1,4-dicarbonitrile (L2) ligands. Compounds 1 and 2 are two-dimensional, while 3 and 4 are three-dimensional. L1 and L2 are 1,4-bis-monodentate ligands in all compounds, while Ag(i) ions are four-coordinated in a slightly distorted tetrahedral geometry. Topological analysis in standard representations suggests that underlying nets in 1 and 2 have an sql topology, while 3 and 4 exhibit a dia topology. Thermal analysis shows that 3 loses crystalline water at room temperature, while other compounds show good thermal stability. All compounds show good photocatalytic activity for photocatalytic degradation of the mordant blue 9 dye, with reaction rates in the range 0.029 to 0.061 min(-1). The best result was obtained for compound 4, which can be correlated to its largest lattice volume.
