Preparation of layered inorganic/organic nanocomposites by nanosecond pulsed laser ablation of Ag in liquids.

A novel layered AgBr-based nanocomposite (designated as AgBr-NC) was prepared using nanosecond pulsed laser ablation in liquids (PLAL) in the presence of cetyltrimethylammonium bromide (CTAB). The obtained layered AgBr-NC possesses well-defined 2D shape. X-ray diffraction (XRD) pattern was composed of a series of peaks that could be indexed to (001) reflections of a layered structure, and the basal spacing of 20.

Mesoporous zinc ferrite: synthesis, characterization, and photocatalytic activity with H2O2/visible light.

Mesoporous ZnFe(2)O(4) (meso-ZnFe(2)O(4)) was synthesized by a hydrothermal process in which cetyltrimethylammonium bromide (CTAB) participates in the reaction to produce nanocrystals. Synthesized ZnFe(2)O(4) was characterized by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area, scanning electronic microscopy (SEM), transmission electron microscopy (TEM), and diffuse reflectance spectra (DRS). The meso-ZnFe(2)O(4) was resulted from the agglomeration of nanoparticles with size of 5-10nm.

A novel wet-scrubbing process using Fe(VI) for simultaneous removal of SO2 and NO.

The objective of this work was to develop a novel wet-scrubbing process using Fe(VI) for the simultaneous removal of gaseous NO and SO(2). The oxidation of SO(2) and NO with Fe(VI) was studied in aqueous solution at alkaline pH (9.0-11.
