A series of bismuth oxyiodide (BiOxIy)-grafted graphene oxide (GO) sheets with different GO contents were synthesized through a simple hydrothermal method. This is the first report where four composites of BiOI/GO, Bi4O5I2/GO, Bi7O9I3/GO, and Bi5O7I/GO have been characterized using X-ray diffraction, transmission electron microscopy, scanning electron microscopy energy-dispersive spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and diffuse reflectance spectroscopy. The assembled BiOxIy/GO composites exhibited excellent photocatalytic activities in the degradation of crystal violet (CV) under visible light irradiation. The order of rate constants was as follows: Bi7O9I3/GO > Bi4O5I2/GO > Bi4O5I2 > Bi7O9I3 > Bi5O7I/GO > BiOI/GO > BiOI > Bi5O7I > GO. The photocatalytic activity of the Bi7O9I3/GO (or Bi4O5I2/GO) composite reached a maximum rate constant of 0.351 (or 0.322) h-1, which was 1.8 (or 1.7) times higher than that of Bi7O9I3 (or Bi4O5I2), 6-7 times higher than that of BiOI/GO, and 119-130 times higher than that of BiOI. The quenching effects of different scavengers and electron paramagnetic resonance demonstrated that the superoxide radical (O2-) played a major role and holes (h+) and hydroxyl radicals (OH) played a minor role as active species in the degradation of crystal violet (CV) and salicylic acid (SA). Possible photodegradation mechanisms are proposed and discussed in this research.

The first synthesis of a triphenylmethine (TM) library of compounds and screening of their Surface Enhanced Raman Scattering (SERS) capability was carried out to identify novel Raman reporters with high sensitivity. We identified three novel SERS reporters (B2, B7, and C7) with higher signal intensity than that of commonly used crystal violet (CV). These reporters may find potential applications in developing sensitive SERS based biosensors.

Photo-Fenton degradation of malachite green catalyzed by aromatic compounds under visible light irradiation

, p. 336 - 341 (2007/10/03)
The photo-Fenton degradation of malachite green (MG) catalyzed by aromatic derivatives under visible light irradiation was examined. Aromatic derivatives exhibit significant catalytic action in the photo-Fenton reaction. The degradation rates of MG with various kinds of aromatic derivatives obey the following order: hydroquinone > salicylic acid > quinone > carboxylic aromatic derivatives > amido aromatic derivatives. GC-MS detection of the products formed in the MG Fenton degradation in the presence of aromatic derivatives shows that the addition of the latter does not change the MG degradation pathways, although it greatly alters the reaction rate. The MG degradation mainly involves two different pathways: cleavage with a [MG-OH]· transition intermediate and N-demethylation.
