The microstructures and chemical compositions of Sn/SiOx core-shell NPs were characterized. In situ heating XRD provides dynamic crystalline information about the Sn/SiOx core-shell NPs during cyclic heating processes. The latent heat of ?29 J g-1 for Sn/SiOx core-shell NPs was measured, and 30% enhanced heat capacity was achieved from 1.57 to 2.03 J g-1 K-1 for the HITEC solar salt without and with, respectively, a mixture of 5% Sn/SiOx core-shell NPs. In addition, an endurance cycle test was performed to prove a stable operation in practical applications. The approach provides a method to enhance energy storage in solar-thermal power plants. ? 2014 the Partner Organisations.journal article10.1039/c3nr06810b2-s2.0-84898648417https://www.scopus.com/inward/record.uri?eid=2-s2.0-84898648417&doi=10.1039%2fc3nr06810b&partnerID=40&md5=acc8153b0cf16820b18c4e53a885a108
