2.1. Synthesis of 1D MgO nanostructures
1D MgO nanostructures were prepared using DC arc plasma jet
CVD with Mg(NO3)2·6H2O as the precursor and Mo nanoparticles
ontheMo substrate surface as the catalyst. Tadpoles,nanobelts, and
nanorods were prepared after 1, 5, and 12 min, respectively. The
main deposition parameters were as follows: Arc power of 18 kW,
argon flow rate of 1.5 L min−1, hydrogen flow rate of 10 L min−1,
substrate temperature maintained at 950 ◦C, and pressure in the
reaction chamber maintained at 4.0 kPa.
