Optimization of UiO-66/CaCl2 composite material for thermal energy storage

Effects of porous carbon materials on heat storage performance of CaCl2 hydrate for low-grade thermal energy

“…The peaks' intensity gets reduced for both matrix and CaCl 2 in the composites as their content decreased. 32 …”

“…Touloumet et al 30,31 developed hierarchical porous AF/Al as the matrix, which showed better heat storage performance (1930 kJ kg −1 for 61 wt% of salt, adsorption at 25 °C, desorption under a heating procedure of 25–150 °C) than single microporous AF and mesoporous Al. Xu et al 32 optimized the UiO-66/CaCl 2 composite and obtain a best heat storage capacity of 1416 kJ kg −1 for around 60 wt% of salt (adsorption at 30 °C, 80% RH). Silvester et al 33 observed a considerable improvement of hydration rate and cycling stability of CaCl 2 after its incorporation into an ordered-mesoporous SBA-15, and present a stable heat storage capacity of 1713.5 ± 32.4 kJ kg −1 for 60 wt% of salt (adsorption at 25 °C, desorption under a heating procedure of 25–150 °C).…”

Synthesis and Characterization of Phase Change Microcapsules Containing Nano-Graphite

“…Given that sources of energy such as petroleum and coal are non-renewable and have environmental concerns, energy-saving, and storage materials are of great significance to sustainable development. Thermal energy storage is divided into sensible heat, latent heat, and chemical energy storage [1][2][3][4]. Among them, phase change material (PCM) attracts attention owing to the function of latent heat storage [5][6][7].…”
