Synthesis of CrSi2 / Cr2O3 Nanocomposite using CaSi2 and CrCl2∙6H2O
Abstract
Chromium-based nanostructures were synthesized from CaSi2 and CrCl2·6H2O powders through controlled thermal annealing under various atmospheres. The selective formation of CrSi2 and Cr2O3 was achieved by tuning the reaction temperature and ambient conditions. CrSi2 appeared as nanorods densely covering the surfaces of gently curved, stacked nanosheets, with rods typically ~100 nm in diameter at the base and elongated along the [0001] axis. The nanosheets were primarily composed of silicon layers, which acted as scaffolds for nanorod growth. In contrast, Cr2O3 formed an entangled wire network with variable diameters, creating a porous morphology that was distinct from the ordered CrSi2 structures.
