Growth of carbon nanofibres on molybdenum carbide nanowires and their self-decoration with noble-metal nanoparticles

X-ray powder diffraction (XRD) was performed at room temperature using Bruker AXS D4 Endeavor diffractometer with Cu-Ka radiation and Sol-X energy-dispersive detector within angular range 2Θ from 10o to 70o with a step size of 0.02o and a collection time of 2 s at a rotation of 6 rpm. EDS spectrum was obtained by high-resolution transmission electron microscope (Jeol JEM-2100F, 200 keV), allowing high contrast imaging and simultaneous EDS.
