摘要: An easy and efficient method (“guanidinium route”) to synthesize vanadium nitride (VN) is evaluated in this paper. Initially, ammonium m-vanadate was mixed with guanidinium carbonate, producing an important intermediate, (GmV), through a solid-state reaction. GmV decomposed as function of the temperature studied TGA, DRX, FT-Infrared, Temperature-Programmed Surface Reaction (TPSR) DFT. We show that transformed into bulk crystalline VN below 800 °C. XPS, periodic DFT calculations, elemental analyses surface not carbon-free.
