Abstract

With the renaissance of chemical electrosynthesis in the last decade, the electrochemistry of hypervalent iodine compounds has picked up the pace and achieved significant improvements. By employing traceless electrons instead of stoichiometric oxidants as the alternative clean “reagents”, many hypervalent iodine compounds were efficiently electro-synthesized via anodic oxidation methods and utilized as powerful redox mediators triggering valuable oxidative coupling reactions in a more sustainable way. This minireview gives an up-to-date overview of the recent advances during the past 3 years, encompassing enhanced electrosynthesis technologies, novel synthetic applications, and ideas for improving reaction sustainability.

Abstract

In this paper, orthorhombic phase zirconium monosilicide nanomaterials have been successfully synthesized through a lithium thermal reduction in a stainless-steel autoclave at a low temperature of 600 0C. X-ray diffraction indicates that the obtained product is orthorhombic zirconium monosilicide. Scanning electron microscopy shows that the obtained zirconium monosilicide product consists of nanoparticles and nanorods. The oxidation resistance of the obtained zirconium monosilicide product is investigated.

Abstract

Hafnium diboride (HfB2) nanoparticles have been prepared by a solid-state reaction of hafnium dioxide (HfO2), metallic magnesium (Mg) and sodium borohydride (NaBH4) at 700°C in an autoclave. The structure and morphology of the obtained product are investigated by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The transmission electron microscopy (TEM) image shows that the average size of HfB2 nanoparticles is about 30 nm. The oxidation behavior of HfB2 is studied by thermogravimetric analysis (TGA). It has good thermal stability and oxidation resistance below 380°C in air. Furthermore, the possible formation mechanism of HfB2 is also discussed.
