Abstract
A low-temperature solvothermal reduction process to nanocrystalline CoAs is reported here. All the precursors are easily accessible. The formation and crystalline temperature of CoAs could be as low as 140 degrees C. Powder X -ray diffraction (XRD) shows a single phase of CoAs. The average particle s ize observed from transmission electron micrography (TEM) is about 18 nm. E lemental analysis and X-ray photoelectron spectroscopy (XPS) were utilized to determine the chemical composition of the product, (C) 1999 Elsevier Sci ence Ltd.
