Abstract Storing energy as heat at temperatures above 200 °C is necessary for both efficient industrial processes and continuous solar energy generation. In this study composite shape-stabilized phase change materials were obtained using mesoporous silica as matrix and the NaNO3 – KNO3 eutectic mixture as the active heat storage component. Five types of mesoporous matrices, including hexagonal MCM-41 and SBA-15, cubic FDU-12 and two mesocellular foam silica were investigated. With the exception…
