In this work, we demonstrate a facile and scalable method to turn low-cost quartz sand into a direct solar-absorbing HTF and TES material by coating a thin silica shell containing black spinel nanoparticles (Cu 0.5 Cr 1.1 Mn 1.4 O 4 and CuCr 2 O 4). The black coating increases the solar absorptances of the sand from ∼0.43 to ∼0.89.
