The effect of titanium nanoparticles on Na-water vapor reaction at 105 °C

We investigated the suppressing effect of Sodium-based Titanium Nanofluid (NaTiNF) on the Sodium-water Vapor Reaction (SVR). The increases in temperature during the reaction of pure sodium (Na) and NaTiNF with water vapor were measured, and surface reaction phenomena were recorded using a high-speed camera. The temperature increase in the reaction of NaTiNF with water vapor was slower than that of Na. From the visualization view, the surface of NaTiNF remained stable whereas the surface of Na reacted vigorously during the reaction. This difference in behavior demonstrates that titanium nanoparticles (Ti NPs) of NaTiNF impede the contact between Na and water, and thereby suppress the chemical reactivity of the SVR.
