| Outline of Final Research Achievements |
A possibility of heat storage materials based on water vapor adsorption on CeO2 nanoparticles has been examined in this study. The CeO2 nanoparticles were prepared by UV-laser irradiation technique. The primary and secondary particle size of CeO2 prepared were estimated to be 3.55 and 8.97 nm, respectively. The amount of water-vapor adsorbed on the CeO2 nanoparticles were 50 cm3/g under p/p0 = 0.4 at 25 degC. Based on this value, their heat storage capacity was calculated to be 165 J/g (0.17 MJ/kg). This capacity can be further improved by using light-weight oxide nanoparticles. The performance as a heat storage device was evaluated by measuring temperature change along with introduction water vapor; the increase in temperature by 0.5 degC was confirmed for approximately 1 h.
