- Abstract
- Suppression of chemical reactivity in reaction between sodium (Na) and water by Na-based titanium nanofluid (NaTiNF) was verified bymeasuring the difference between theH2 generation rates ofNaTiNF-water reaction and sodium-water reaction (SWR). H2 generation at the beginning of the reaction was slower in NaTiNF-water reaction than in SWR. To determine the effect of temperature on the reaction rate, NaTiNF-water reactions were conducted at 104 degrees C, 120 degrees C and 150 degrees C. At 104 degrees C, the reaction rate of SWR was twice as fast as NaTiNF-water reaction. This result demonstrates that the chemical reactivity of liquid Na is suppressed by the presence of Ti nanoparticles in liquid Na. The reaction rate of NaTiNF-water reaction increased with reaction temperature. The activation energy of NaTiNF-water reaction was obtained using the Arrhenius equation.
