Photocatalytic activity of layered MoS in the reductive degradation of bromophenol blue.

Molybdenum disulphide (MoS) is a layered material with interesting photocatalytic properties. In this study, a layered MoS was produced using a hydrothermal method. The obtained material was characterised by XRD (X-ray diffraction), XPS (X-ray photoelectron spectroscopy), SEM (scanning electron microscopy), UV-Vis spectroscopy, DLS (dynamic light scattering), and zeta potential analysis.

Selenium-Modified Microgels as Bio-Inspired Oxidation Catalysts.

Active colloidal catalysts inspired by glutathione peroxidase (GPx) were synthesized by integration of catalytically active selenium (Se) moieties into aqueous microgels. A diselenide crosslinker (Se X-linker) was successfully synthesized and incorporated into microgels through precipitation polymerization, along with the conventional crosslinker N,N'-methylenebis(acrylamide) (BIS). Diselenide bonds within the microgels were cleaved through oxidation by H O and converted to seleninic acid whilst maintaining the intact microgel microstructure.
