“…The term 'nanocomposite' is used to describe a multiphase solid material in which one of the phases has one, two or three dimensions of less than 100 nm. 1 Nanocomposites frequently exhibit properties (or a combination of properties) not available through any of the components in the composite individually. The fabrication of nanocomposite materials therefore promises access to previously unachievable properties of technological importance in applications 2 including LEDs, lasers, non-linear optical devices 3 and bio-labelling.…”

Recent studies have shown that SnO2-based nanocomposites offer excellent electrical, optical, and electrochemical properties. In this article, we present the facile and cost-effective fabrication, characterization and testing of a new SnO2-PbS nanocomposite photocatalyst designed to overcome low photocatalytic efficiency brought about by electron-hole recombination and narrow photoresponse range. The structure is fully elucidated by X-ray diffraction (XRD)/Reitveld refinement, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area analysis, and transmission electron microscopy (TEM). Energy-dispersive X-ray spectroscopy (EDX) spectrum imaging analysis demonstrates the intermixing of SnO2 and PbS to form nanocomposites. A charge separation mechanism is presented that explains how the two semiconductors in junction function synergistically. The efficacy of this new nanocomposite material in the photocatalytic degradation of the toxic dye Rhodamine B under simulated solar irradiation is demonstrated. An apparent quantum yield of 0.217 mol min(-1) W(-1) is calculated with data revealing good catalyst recyclability and that charge separation in SnO2-PbS leads to significantly enhanced photocatalytic activity in comparison to either SnO2 or PbS.

“…Schiff-bases of the amino acid and the ketone were separated in case of metal acetates where the pH (5) is suitable for condensation while in case of metal chlorides the lower pH (2)(3)(4) blocks NH 2 as NH þ 3 , the amino acid and the ketone coordinate separately to the metal ion to form mixed ligand complexes. The majority of work has been carried out on salicylaldehyde and its derivatives [28,29]. No work has been carried out on the metal complexes derived from glycine and 2-acetylpyridine.…”

Metal complexes with HATU of so far unknown structure include the nitrosyl complexes with Co, Fe and Ru (Roy & Saha, 1980); the complexes with Co and Hg (Poddar & Ray, 1952); and those with Cu, Ag and Zn (Roy & Saha, 1980). HATU has also been used as a component of resins chelating such ions as Ag + (Trochimczuk & Kolarz, 2000).…”

Two oxidation products of 1-(diaminomethylene)thiourea (HATU) are reported, obtained from reactions with hydrogen peroxide at two different concentrations; these are 3,5-diamino-1,2,4-thiadiazole, C(2)H(4)N(4)S, (I), related to HATU by intramolecular N-S bond formation, and 1-(diaminomethylene)uronium hydrogen sulfate, C(2)H(7)N(4)O(+).HSO(4)(-), (II). In (I), molecular hydrogen-bonded chains could be distinguished, further organized in a herring-bone-like pattern. The structure of (II) is stabilized by an extensive network of N-H...O and O-H...O hydrogen bonds, where hydrogen-bonded anion chains and characteristic cation-anion motifs are present. The compounds are of importance not only with respect to crystal engineering, but also in the design of new synthetic routes to HATU transition metal complexes.
