摘要

Development of advanced materials with high energy density for thermochemical energy storage may contribute to the efficient utilization of solar energy and waste heat. In this work, Ce(NO₃)₃/Mg(OH)₂ as a new heat storage material for TCEs was investigated. The effect of Ce(NO₃)₃ on dehydration of Mg(OH)₂ was investigated by differential scanning calorimetry and thermogravimetry techniques. The addition of Ce(NO₃)₃ can significantly reduce the dehydration temperature and accelerate the dehydration of Mg(OH)₂. The temperature reduction depends on the Ce(NO₃)₃ content W and reaches 29 °C at W = 10 wt%, while the dehydration heat was reduced only slightly (1086 J/g). The new material exhibits an adjustable decomposition temperature, fast dehydration rate and large heat storage density, and may be considered as a promising candidate for thermochemical storage of concentrated solar energy.
